# AccelMeter vs PeakG

The clearest difference is rating: PeakG at 4.0 against AccelMeter's 2.7. PeakG also leads on monetization model (free vs paid). AccelMeter's advantage is review sentiment (48% vs 33%) and ratings volume (10 vs 2). On price, update cadence, ads and in-app purchases there is nothing between them.

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

PeakG holds the better App Store score, 4.0 against 2.7. That said, the two scores are not equally well evidenced: AccelMeter has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 48% of AccelMeter'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.

AccelMeter ships an update every 6 months, PeakG every 10 months. The most recent releases landed on October 13, 2026 and October 30, 2026 respectively.
