Version 1.0.4

May 2026 · New features and bug fixes

• Paywall Added a row for digit fonts; Archive and Export moved to the bottom of the list. Fixed the premium font count: listed as 5, correct value is 4 (Classic is free). Added proper spacing below the Privacy, Terms and Support links.
• NL parser Bill splitting ("split", "auf 3 aufteilen", "dividi per 3"…) was not working in all 11 languages. Fixed.
• Tape Divider was showing the currency symbol instead of the number (÷ $3 → ÷ 3). Tip was showing the multiplier instead of the amount (× 1 → + €42).
• Pixel Art Tape and display panel stopped using the Silkscreen font after the digit font picker was added. Fixed.
• Themes The digit font selection was incorrectly applied to Texas, All Black, Palmtron, Dieter and Pixel Art: these palettes use a fixed native font. Font picker cards were not respecting the active palette colours (affected dark themes).

Version 1.0.3
