ASTROTIMER turns your countdown into a cosmic experience. Set your timer, and watch as asteroids fill the starry sky — one for each minute. A glowing ball bounces between them, producing beautiful FM synthesis chimes with every collision. As each minute passes, a rock shatters into fragments, scattering across the screen. When time's up, a gentle chime melody lets you know. Features: Stunning real-time star chart background Physics-based ball and rock collisions FM synthesis chime sounds with delay and reverb Timer from 0:10 to 30:00 Remembers your last timer setting Works on iPhone and iPad

Verdict
The clearest difference is in-app purchases: Triple Notes at none against ASTROTIMER's 1. ASTROTIMER's advantage is update cadence (every 6 days vs every 2 weeks). On price, ads, device support and iOS requirement there is nothing between them.
