QuickSpend

Version 4: dark mode, all buttons and pills at least 44px tall, and each expense now gets its own id so deleting one never removes another. Saved data format unchanged (data version 2).

Version 3: This Month total on the card and Export to CSV. Saved data format unchanged (data version 2), so phones with Version 2 data open normally.

Version 2: categories, Cash/UPI payment method, tags on each row, Cash and UPI breakdown. Existing expenses are kept.

First version: daily expense tracker in rupees.
