PULSE

One particle. One orbit. One touch. PULSE is a rhythm-reflex survival game where everything moves to the music. Rings close in on the beat of a fully synthesized soundtrack, the haptics pulse in your hand, and one hit ends the run. The controls take three seconds to learn: • TAP to reverse direction • HOLD to dive to the inner orbit • That's all. Really. The first minute welcomes you. Everything after that is war. Speed rises, gaps narrow, patterns stack — and the world's best runs are measured in seconds. Restarts are instant, so "one more run" is always half a second away. FEATURES • Beat-synced everything — obstacles, visuals and Core Haptics ride one synthesized soundtrack that accelerates as you survive • Easy to start, hell to master — an invisible tutorial ramp, then a skill ceiling in the clouds • DAILY CHALLENGE — the whole world plays the same seed every day. Same rings, same order, one leaderboard. Learn it, master it, own it • GHOSTS — race the translucent replay of your best run; in the Daily it dodges the exact rings you see • GAME CENTER — global and daily leaderboards, 8 achievements • iCLOUD SYNC — your records follow you across devices • ACCESSIBILITY — Reduce Motion support, colorblind-friendly palettes, and obstacles that differ by shape, not just color • 120Hz ProMotion, beat-synced haptics, and a download measured in megabytes FAIR BY DESIGN No ads. No accounts. No energy bars. No pay-to-win — ever. The optional shop sells cosmetics only: themes, particle skins and soundtrack packs. Every player faces exactly the same game. Your best run is 20 seconds? So was ours, for a while. Stay in sync.

Verdict
The clearest difference is ads: PULSE at none against O's shown. O's advantage is chart position (#121 vs unranked). On price, in-app purchases, device support and iOS requirement there is nothing between them.
