Two new features in one session: three pre-recorded WAV click sounds you can pick alongside the existing synth click, and press-and-hold haptic feedback on the main tempo circle. Plus a long debugging detour that turned out to be a lazy-init bug in the native engine.
Eight items from the first round of beta feedback, in one focused day. A subtle Compose race condition that broke Feel-the-Beat, a rename of “Special Entry” to “Break”, per-playlist rename via a 3-dot overflow menu, an in-library New Song affordance, a system-nav clipping fix, a restructured top-bar menu, and the first version of an Edit Sound screen with live frequency and tone control plumbed all the way down to the Oboe callback.
A split session: two new knowledge base articles in the morning, then a long evening of wiring up swipe gestures and drag-to-reorder — including a detour through a custom implementation that never fully worked, ending with the right library call.
The metronome clicks on a real Android device. Here’s how Claude handled the architecture, Gemini wrote the code, and I directed traffic between them.
