Nouveautés (v1.4)
What's New in Version 1.0.7
-Brand New Design
Complete visual redesign with a premium dark theme inspired by modern app aesthetics. The app now features a deep navy background with ambient glow effects, glassmorphism cards, and a clean typographic hierarchy that makes navigation feel effortless.
- Upgraded Touch Draw Test
The touch drawing test has been completely rebuilt from the ground up:
- Live coverage grid — the screen divides into cells that highlight as you draw, showing exactly which areas you've tested
- Coverage percentage bar — tracks how much of your screen surface you've covered in real time
- Color picker — choose from 6 brush colors to draw with
- Brush size selector — 4 thickness levels from fine to thick
- Live stats — active finger count, maximum fingers detected, and total stroke count
- New: Multitouch Test
A dedicated test to verify your screen's multitouch capability. Place multiple fingers simultaneously and see each one tracked with a numbered, color-coded circle. Displays both the current finger count and the maximum number of simultaneous touches detected — ideal for confirming 5 or 10-point multitouch support.
- New: Response Test
Measures touch latency with every tap. See your last tap time in milliseconds, a running average, and a live bar chart of your last 10 taps color-coded by speed — green for fast, yellow for moderate, red for slow. Great for spotting screen responsiveness issues.
- Under the Hood
Removed third-party ad dependencies for a leaner, faster app. All tests now use only built-in Expo and React Native components, improving stability and compatibility across all devices.
