## Version history (last 5 releases)

### 3.0 — 2026-07-24

A major design update for iOS 26!

• Liquid Glass — the task, keyboard and statistics cards now use the new iOS 26 material that beautifully refracts the background
• The active answer field is highlighted with a floating glass capsule — just like the iOS 26 tab bar — smoothly gliding between X₁ and X₂
• Switch between answer fields with a simple tap on X₁ or X₂
• Haptic feedback on every keyboard tap
• The app has been fully rewritten on a modern stack — faster and smoother
• Small interface refinements in dark and light themes

On devices running iOS below 26 the app keeps its familiar look.
