🔧 Subscription Tracker Currency Fixes

Date: October 21, 2025
Issues: Subscription dialog and stats ignore user's currency selection
Priority: Medium (2 bugs)
Status: ✅ FIXED

🐛 Bugs Identified

Bug 1: Dialog Hardcoded Currency Symbol

Location: SubscriptionTrackerScreen.kt:580
Severity: Medium
Impact: Users see wrong currency symbol when adding/editing subscriptions

Problem:

leadingIcon = { Text("৳") }  // ❌ Always shows "৳"

The subscription dialog's cost input field had a hardcoded "৳" symbol, ignoring the user's selected currency from their profile.

Bug 2: Stats Views Ignore Currency Selection

Locations:

  • Line 1067: Monthly Total
  • Line 1074: Yearly Total
  • Line 1095: Average per Subscription
  • Line 1246: Category Spending

Severity: Medium
Impact: All stats and totals display with default "৳" instead of user's currency

Problem:

// ❌ Missing currency parameter
SubscriptionAnalytics.formatCurrency(stats.totalMonthly)
SubscriptionAnalytics.formatCurrency(stats.totalYearly)
SubscriptionAnalytics.formatCurrency(stats.avgCostPerSub)
SubscriptionAnalytics.formatCurrency(spending.monthlyTotal)

All formatCurrency() calls were missing the currency parameter, causing them to fall back to the default "৳".

✅ Fixes Applied

Fix 1: Dynamic Currency in Dialog

Before:

// Line 580
leadingIcon = { Text("৳") }  // ❌ Hardcoded

After:

// Line 580
leadingIcon = { Text(currency) }  // ✅ Dynamic

How it works:

  • The SubscriptionDialog composable already receives currency as a parameter (line 483)
  • Changed the hardcoded "৳" to use the currency variable
  • Now displays the user's selected currency from their profile

Fix 2: Pass Currency to All Stats

Before:

// Lines 1067, 1074, 1095, 1246
SubscriptionAnalytics.formatCurrency(amount)  // ❌ Missing parameter

After:

// Lines 1067, 1074, 1095, 1246
SubscriptionAnalytics.formatCurrency(amount, currency)  // ✅ With currency

Changes made:

  1. Monthly Total (Line 1067)
value = SubscriptionAnalytics.formatCurrency(stats.totalMonthly, currency)
  1. Yearly Total (Line 1074)
value = SubscriptionAnalytics.formatCurrency(stats.totalYearly, currency)
  1. Average per Sub (Line 1095)
value = SubscriptionAnalytics.formatCurrency(stats.avgCostPerSub, currency)
  1. Category Spending (Line 1246 + Function Signature)
// Updated CategorySpendingCard to accept currency
fun CategorySpendingCard(spending: SubscriptionAnalytics.CategorySpending, currency: String)

// Updated the formatCurrency call
text = SubscriptionAnalytics.formatCurrency(spending.monthlyTotal, currency)

// Updated the call site (Line 1130)
CategorySpendingCard(spending = spending, currency = currency)
