# Accelerometer vs Horizontal Accelerometer

The clearest difference is in-app purchases: Horizontal Accelerometer at none against Accelerometer's 1. Horizontal Accelerometer also leads on update cadence (every 6 weeks vs every 5 months) and iOS requirement (13.0 vs 17.6). Accelerometer's advantage is ads (none vs shown). On price, review sentiment and device support there is nothing between them.

Both are free to download. Accelerometer sells 1 one-off in-app purchase. Horizontal Accelerometer asks for nothing beyond the download.

Accelerometer ships an update every 5 months, Horizontal Accelerometer every 6 weeks. The most recent releases landed on October 6, 2026 and October 7, 2026 respectively.
