(Preferences-general)=
Units
- Set units to mmol/l or mg/dl depending on your preferences.
Language
-
New option to use phone's default language (recommended).
-
In case you want AAPS in a different language than your standard phone language, you can choose from a broad variety.
-
If you use different languages, you might sometimes see a language mix. This is due to an android issue where overriding the default android language sometimes doesn't work.

Setting hidden in simple mode.
(preferences-simple-mode)= Simple mode
The simple mode is activated by default when you first install AAPS. In simple mode, a significant amount of settings is hidden and preferences are replaced by predefined values. Additional graphs on the HomePage are also predefined for you. You should switch off Simple mode once you become familiar with AAPS user interface and settings.
Patient name
- Can be used if you have to differentiate between multiple setups (i.e. two T1D kids in your family).
- Displayed in the Dual Watchface.
(Preferences-skin)=
Setting hidden in simple mode.
You can choose from four types of skins:
'Low resolution skin' comes with shorter labels and age/level removed to have more available space on a very low resolution screen.
Difference between the other skins depends on the phone's display orientation:
- Original Skin and Buttons are always displayed on bottom of screen are identical
- Large Display has an increased height for all graphs compared to other skins
-
Using Original Skin and Large Display, you have to scroll down to see buttons at the bottom of the screen
-
Large Display has an increased height for all graphs compared to other skins
(Preferences-protection)=
(Preferences-master-password)=
Mandatory to be able to export settings as they are encrypted from version 2.7.
Biometric protection may not work on OnePlus phones. This is a known issue of OnePlus on some phones.
-
Protect your settings with a password or phone's biometric authentication (i.e. child is using AAPS). If you enable this feature, you will be prompted for authentication each time you want to access any Preferences related view.
-
Custom password should be used if you want to use master password just for securing exported settings, and use a different one for editing the preferences.
-
If you are using a custom password click on line "Settings password" to set password as described above.
If the app is protected, you must enter the password or use the phone's biometric authentication to open AAPS.
AAPS will shut down immediately if a wrong password is entered - but will still run in background if it was previously opened successfully.
-
Bolus protection might be useful if AAPS is used by a small child and you bolus via SMS.
-
In the example below you see the prompt for biometric protection. If biometric authentication does not work, click in the space above the white prompt and enter thr master password.
Define how long (in seconds), the preferences or bolus functionalities remain unlocked after you successfully enter the password.
In the Overview section, you can define the preferences for the home screen.
Option 'Keep screen on' will force Android to keep the screen on at all times. This is useful for presentations etc. But it consumes a lot of battery power. Therefore, it is recommended to connect the smartphone to a charger cable.
(Preferences-buttons)=
- Define which buttons are visible on the bottom of your home screen.
- Setting hidden in simple mode.
- The Increment options allow you to define the amount for the three buttons in the carb and insulin dialogues, for easy entry.
(Preferences-quick-wizard)=
Create customized buttons for certain standard meals or snacks which will be displayed on the home screen. Useful for standard meals frequently eaten.
For each button, you define the carbs and calculation method for the bolus. Then, you define during which time period the button will be visible on your home screen - just one button per period. The button will not be visible if outside the specified time range or if you have enough IOB to cover the carbs defined in the QuickWizard button. If different times are specified for the different meals you will always have the appropriate standard meal button on the home screen, depending on the time of day.
If you click the quick wizard button AAPS will calculate and propose a bolus for those carbs based on your current ratios (considering blood glucose value or insulin on board if set up).
The proposal has to be confirmed before insulin is delivered.
Only one QuickWizard button can show up at the same time. If you want to execute a different one : long press on the Quick Wizard button currently showing. It will take you to the list of all Quick Wizard options. To execute one, long press on it. You will have to confirm before execution.
(Preferences-default-temp-targets)=
Setting hidden in simple mode.
Temporary targets (TT) allow you to change your blood glucose target for a certain time period. When setting a default TT, you can easily change your target for activity, eating soon etc.
Here you can change the target and the duration for each predefined TT. Preset values are:
- Eating soon: target 72 mg/dL / 4.0 mmol/l, duration 45 min
- Activity: target 140 mg/dL / 7.8 mmol/l, duration 90 min
- Hypo: target 125 mg/dL / 6.9 mmol/l, duration 45 min
Learn how to activate Temp Targets here.
Setting hidden in simple mode.
If you want to fill the tube or prime cannula through AAPS you can do this through the Actions tab.
Pre-set values can be defined in this dialogue. Choose the default amounts of the three buttons in fill/prime dialogue, depending on the length of your catheter.
(Preferences-range-for-visualization)=
Choose the high and low marks for the BG-graph on AAPS overview and smartwatch. It is only the visualization, not the target range for your BG. Example: 70 - 180 mg/dl or 3.9 - 10 mmol/l
Setting hidden in simple mode.
Useful to see more tab titles on screen.
For example the 'OpenAPS AMA' tab becomes 'OAPS', 'OBJECTIVES' becomes 'OBJ' etc.
(Preferences-show-notes-field-in-treatments-dialogs)=
Setting hidden in simple mode.
Gives you the option to add short text notes to your treatments (bolus wizard, carbs, insulin...)
(Preferences-status-lights)=
Setting hidden in simple mode.
Status lights give a visual warning for:
- Sensor age
- Sensor battery level for certain smart readers (see screenshots page for details).
- Insulin age (days reservoir is used)
- Reservoir level (units)
- Cannula age
- Pump battery age
- Pump battery level (%)
If the warning threshold is exceeded, values will be shown in yellow. If the critical threshold is exceeded, values will be shown in red.
The last option allows you to import those settings from Nightscout if defined there. See Nightscout documentation for more information.
(Preferences-deliver-this-part-of-bolus-wizard-result)=
Set the default percentage of the bolus calculated when using the bolus wizard.
Default is 100%: no correction. Even when setting a different value here, you can still change each time you use the bolus wizard. If this setting is 75 % and you had to bolus 10U, the bolus wizard will propose a meal bolus of only 7.5 units.
When using SMB, many people do not meal-bolus 100% of needed insulin, but only a part of it (e.g. 75 %) and let the SMB with UAM (Unattended Meal Detection) do the rest. Using a value lower than 100% here can be useful:
- for people with slow digestion: sending all the bolus upfront can cause hypo because the insulin action is faster than the digestion.
- to leave more room to AAPS to deal by itself with BG rise. In both cases, AAPS will compensate for the missing part of the bolus with SMBs, if/when deemed adequate.
If the last BG received is older than this threshold, then the bolus wizard will by default offer a 100% dose instead of the Deliver this part of bolus wizard result setting above. The reason for this is that when BG is missing, AAPS will not be able to send the remaining part of the bolus afterward (the loop is not running), which would result in high BG.
Setting hidden in simple mode.
When enabled, when you use the bolus wizard as you are in hyperglycemia, you will get a warning, prompting you if you wish to pe-bolus and eat later, when your BG gets back in range.

Option to enable superbolus in bolus wizard.
Superbolus is a concept to "borrow" some insulin from basal rate in the next two hours to prevent spikes. It is different from super micro bolus!
Use with caution and do not enable it until you learn what it really does. Basically, the basal for the next two hours is added to the bolus and a two hour zero-temp activated. AAPS looping functions will be disabled - so use with care! If you use SMB AAPS looping functions will be disabled according to your settings in "Max minutes of basal to limit SMB to", if you do not use SMB looping functions will be disabled for two hours. Details on super bolus can be found here.
(preferences-patient-type)=
- Safety limits are set based on the age you select in this setting.
- If you start hitting these hard limits (like max bolus) it's time to move one step up.
- It's a bad idea to select higher than real age because it can lead to overdosing by entering the wrong value in the insulin dialog (by skipping the decimal dot, for example).
- If you want to know the actual numbers for these hard-coded safety limits, scroll to the algorithm feature you are using on this page.
- Defines the maximum amount of bolus insulin, in insulin units, that AAPS is allowed to deliver at once.
- This setting exists as a safety limit to prevent the delivery of a massive bolus due to accidental input or user error.
- It is recommended to set this to a sensible amount that corresponds roughly to the maximum amount of bolus insulin that you are ever likely to need for a meal or correction dose.
- This restriction is also applied to the results of the bolus calculator.
- Defines the maximum amount of carbs, in grams, that AAPS bolus calculator is allowed to dose for.
- This setting exists as a safety limit to prevent the delivery of a massive bolus due to accidental input or user error.
- It is recommended to set this to a sensible amount that corresponds roughly to the maximum amount of carbs that you are ever likely to need for a meal.
As of AAPS version 3.4, it is no longer possible to set the loop mode here. See AAPS Screens > The Homescreen > Loop status to change loop mode now.
(Preferences-minimal-request-change)=
When using Open loop, you will receive notifications every time AAPS recommends adjusting the basal rate. To reduce the number of notifications you can either use a wider bg target range or increase the percentage of the minimal request rate. This defines the relative change required to trigger a notification.
Depending on your settings in Config builder > APS you can choose between two algorithms:
- Advanced meal assist (OpenAPS AMA) - state of the algorithm in 2017
- Super Micro Bolus (OpenAPS SMB) - most recent algorithm recommended for beginners
As of AAPS version 3.3, Dynamic ISF feature has been moved as part of OpenAPS SMB.
All the settings for OpenAPS AMA are described in the dedicated section in Key AAPS Features > Advanced Meal Assist (AMA).
(Preferences-openaps-smb-settings)=
All the settings for OpenAPS SMB are described in the dedicated section in Key AAPS Features > Super Micro Bolus (SMB).
(Preferences-min_5m_carbimpact)=
Setting hidden in simple mode.
The algorithm uses BGI (blood glucose impact) to determine when carbs are absorbed.
At times when carb absorption can’t be dynamically worked out based on your blood's reactions, AAPS inserts a default decay to your carbs. Basically, it is a failsafe. This value is only used during gaps in CGM readings or when physical activity “uses up” all the blood glucose rise that would otherwise cause AAPS to decay COB.
To put it simply: The algorithm "knows" how your BGs should behave when affected by the current dose of insulin etc. Whenever there is a positive deviation from the expected behaviour, some carbs are absorbed/decayed. Hierbij geldt: grote verandering = veel koolhydraten.
The min_5m_carbimpact does define the default carb absorption impact per 5 minutes. For more details see OpenAPS docs.
Standard value for AMA is 5, for SMB it's 8.
The COB graph on the home screen indicates when min_5m_impact is being used by putting an orange circle at the top.
If you often eat high fat or protein meals you will need to increase your meal absorption time.
- Define min. and max. autosens ratio.
- Normally standard values (max. 1.2 and min. 0.7) should not be changed.
Activate BT watchdog if necessary (e.g. for Dana pumps). It switches off bluetooth for one second if no connection to the pump is possible. This may help on some phones where the bluetooth stack freezes.
The options here will vary depending on which pump driver you have selected in Config Builder > Pump. Pair and set your pump up according to the pump related instructions.
More information on the dedicated Tidepool page.
(Preferences-nsclient)=
Original communication protocol, can be used with older Nightscout versions.
- Set your Nightscout URL (i.e. https://yoursitename.yourplaform.dom).
- Make sure that the URL is WITHOUT /api/v1/ at the end.
- The API secret (a 12 character password recorded in your Nightscout variables).
- This enables data to be read and written between both the Nightscout website and AAPS.
- Double check for typos here if you are stuck in Objective 1.
New protocol introduced with AAPS 3.2. Safer and more efficient.
:class: warning
When using NSClientV3, all uploaders must be using the API V3. Since most are not compatible yet, this means **you must let **AAPS** upload all data** (BG, treatments, ...) to Nightscout and disable all other uploaders if they're not V3 compliant.
- Set your Nightscout URL (i.e. https://yoursitename.yourplaform.dom).
- Make sure that the URL is WITHOUT /api/v1/ at the end.
- In Nightscout, create an Admin token (requires Nightscout 15 to use the V3 API) and enter it in the NS access token (not your API Secret!).
- This enables data to be read and written between both the Nightscout website and AAPS.
- Double check for typos here if you are stuck in Objective 1.
- Leave Connect to websockets enabled (recommended).
(Preferences-nsclient-synchronization)=
Synchronization choices will depend on the way you will want to use AAPS.
You can select which data you want to upload and download to or from Nightscout.
- Alarm options allows you to select which Nightscout alarms to use through the app. AAPS will alarm when a Nightscout alarm triggers.
- For the alarms to sound you need to set the Urgent High, High, Low and Urgent Low alarm values in your Nightscout variables.
- They will only work whilst you have a connection to Nightscout and are intended for parent/caregivers.
- If you have the CGM source on your phone (i.e. xDrip+ or BYODA) then use those alarms instead of Nightscout Alarms.
- Create notifications from Nightscout announcements will echo Nightscout announcements in the AAPS notifications bar.
- You can change stale data and urgent stale data alarms threshold when no data is received from Nightscout after a certain time.
- Connection settings define when Nightscout connection will be enabled.
- Restrict Nightscout upload to Wi-Fi only or even to certain Wi-Fi SSIDs.
- If you want to use only a specific Wi-Fi network you can enter its Wi-Fi SSID.
- Multiple SSIDs can be separated by semicolon.
- To delete all SSIDs enter a blank space in the field.
(Preferences-advanced-settings-nsclient)=
Options in advanced settings are self-explanatory.

Email recipient: Standard recipient of logs is logs@aaps.app.
Data Choices
You can help develop AAPS further by sending crash reports to the developers.
Unattended Settings Export
By enabling this feature, you allow AAPS to execute settings exports without user intervention. For this the master password is securely stored on your phone (only) at the next manually export. The stored password will be used for up to 4 weeks. After 4 weeks you will be notified the password is about to expire. During a grace period of 1 week, the password can then be refreshed by manually exporting settings from the maintenance menu.
After the grace period of 1 week has passed the stored password expires and any automated settings export will abort while notifying the user, asking to reenter the password. (Automated settings exports) will be logged to the AAPS 'Careportal' and 'User entry' lists under Treatments.
After enabling this option, make sure to perform a manual settings export, where you will be requested for your password, so that AAPS can store it.
AAPS will save logs for troubleshooting.
Do not disable this feature: it will help understanding the reasons if something goes wrong.
If you need to send the logs to the developers, make sure you file accurately the mail contents to describe the issue. It is preferable to send logs only after being requested to do so, following an issue report in GitHub.
You can find AAPS logs in your phone memory -> Android -> data -> info.nightscout.androidaps -> files.
(preferences-maintenance-logdirectory)=
Maintenance settings also include the AAPS directory, which can be found directly under the Maintenance tab. This setting allows the user to choose a directory on their phone where AAPS will store preferences, logs, and other files.
It is strongly recommended to use a directory directly in the main entry of your phone memory. Default is AAPS.
If you select a subdirectory of AAPS, you will see an error message. Tap "OK" and retry, selecting the correct directory (one above). Do not select "DISMISS" unless you clearly know what you are doing.
(preferences-maintenance-cloud)=
You can export your settings, logs and CSV data to a cloud service.
- Select Cloud directory
- Select your cloud service
- Enable cloud export
You can then define what data will be uploaded to the cloud.
You can disable cloud export.
