# AccelMeter vs Horizontal Accelerometer

The clearest difference is ads: AccelMeter at none against Horizontal Accelerometer's shown. AccelMeter also leads on iOS requirement (10.0 vs 13.0). Horizontal Accelerometer's advantage is monetization model (ad-supported vs paid) and update cadence (every 6 weeks vs every 6 months). On price, review sentiment, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

AccelMeter ships an update every 6 months, Horizontal Accelerometer every 6 weeks. The most recent releases landed on September 22, 2026 and September 12, 2026 respectively.
