Interval Study Timer v1.0.1
🐛 Bug Fixes & UI Improvements
Fixed: Layout broken on physical devices
Views were positioned using tools:layout_editor_absoluteX which only renders correctly in Android Studio's preview — on real devices, elements were misaligned or overlapping. All views now use proper ConstraintLayout anchors.
Fixed: Hardcoded width on RecyclerView
Sessions list was set to a fixed 411dp width, causing it to overflow or appear narrow on devices with different screen densities. Changed to 0dp with start/end constraints.
Fixed: Bottom navigation spacing
Bottom nav bar lacked padding for Android's gesture navigation inset, causing it to appear unnaturally high on newer devices.
Improved: Vertical layout on larger screens
Dashboard elements now use a proper vertical chain — the timer ring stays near the top and action buttons anchor to the bottom, with free space distributed naturally in the middle on larger displays.
Improved: Consistent margins
Replaced fragile horizontal_bias positioning with explicit marginStart values for predictable alignment across all screen sizes.
📱 Tested on
Physical Android device (edge-to-edge, gesture navigation)
