The whole app switches instantly without restarting. "No bill this month" option — Tap Mark Paid on any bill to see a new "No bill this month" link. Use it when a credit card had no statement this cycle — dismisses it cleanly without affecting your totals. Calendar fix — The date picker in Edit Bill now matches your selected appearance instead of always showing in light mode. ### 1.0.7 — 2026-07-15 Bug Fixes Sorting — Bill list now sorts by due date ascending across all buckets (recurring instances were appending after direct DB records unsorted) Paid bucket sort — "Already paid" now sorts by payment date, so marking a bill paid doesn't scramble the list Duplicate on backup restore — Importing a backup re-assigns SQLite IDs, breaking original_bill_id references; fixed by preserving original IDs on import Dark mode crash — DarkTheme not exported from react-native-paper v5 caused a crash on dark mode switch Features Recurring bill service — getRecurringInstanceForMonth + getBillInstancesForMonth extracted to services/recurringBills.js with full unit test suite (12 tests) "Decide at Save" scope dialog — When editing a recurring instance, a sheet appears at save time: "This month only" vs "This and all future months" Keyboard Done button scoped — "Done" toolbar on keyboard now only appears when the Amount Due field is focused (not card name or other fields) Hybrid dedup for backup compatibility — Old backup data (no original_bill_id) uses name-based fallback so imported paid bills aren't shown as overdue Package updates expo → 54.0.35, expo-file-system → 19.0.23, expo-localization → 17.0.9 ### 1.0.6 — 2026-05-27 Added "Rate BillStack" in Settings — tap to leave a review ### 1.0.5 — 2026-05-21 Bug fixes and improvements: • Tap the month title to jump to any month instantly • Notification settings now apply immediately to existing bills • Local backup restore — tap any backup to restore with confirmation • Date rules: payment date must be today or past, scheduled date must be future • Bills with no amount now show "TBD" instead of appearing blank • Clearer context when editing a recurring bill for a specific month • Fixed: editing a paid bill no longer triggers date validation errors • Fixed: opening Edit Bill without changes no longer shows a discard warning ### 1.0.3 — 2026-05-17 Bug Fixes: Opening Edit Bill and pressing X without changing anything no longer shows the discard dialog Opening Add Bill and pressing X without typing anything no longer shows the discard dialog Editing a paid bill (e.g. changing category only) no longer triggers date validation errors Fixed a timezone bug that caused false "unsaved changes" warnings when editing Mark as Paid: "Mark Paid" button now clearly looks like an action (blue outline, empty circle) instead of a status badge Tapping "Mark Paid" now shows a confirmation with today's date before saving After marking paid, if no scheduled date is set, app prompts to add when payment will clear Analytics: Recurring bills now show the correct category in the breakdown (was showing wrong category) Month labels (Dec, Jan…) no longer get clipped at the bottom of the chart Month Navigation: Tap the month title (e.g. "May 2026") to jump directly to any month — no more clicking arrows many times Navigation limit removed — can now scroll to any month past or future Month picker shows 3 years with a close button (was showing 5 years, too many) Date Rules: Payment date now blocked if set to a future date Scheduled date now blocked if set to a past date Statement date warns if more than 6 months in the past --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
