# Planet Formula vs Gravity Whisper

The clearest difference is ads: Gravity Whisper at none against Planet Formula's shown. Gravity Whisper also leads on update cadence (every 2 weeks vs every 2 months). Planet Formula's advantage is device support (4 vs 2) and iOS requirement (13.0 vs 17.6). On price and in-app purchases there is nothing between them.

Planet Formula ships an update every 2 months, Gravity Whisper every 2 weeks. The most recent releases landed on October 22, 2026 and October 13, 2026 respectively.
