# Accelerometer vs PeakG

The clearest difference is rating: PeakG at 4.5 against Accelerometer's 4.0. PeakG also leads on in-app purchases (none vs 1) and ratings volume (4 vs 1). Accelerometer's advantage is review sentiment (54% vs 33%) and update cadence (every 5 months vs every 10 months). On price, ads, device support and iOS requirement there is nothing between them.

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

PeakG holds the better App Store score, 4.5 against 4.0. Both are backed by a comparable volume of ratings — 1 and 4 respectively. Written reviews complicate that: 54% of Accelerometer's written reviews are positive against 33% of PeakG's, so the app with the better star average is not the one people write more warmly about.

Accelerometer ships an update every 5 months, PeakG every 10 months. The most recent releases landed on November 1, 2026 and November 5, 2026 respectively.
