Verdict
The clearest difference is rating: Seismometer+ at 4.5 against Accelerometer's 4.0. Seismometer+ also leads on in-app purchases (none vs 1) and ratings volume (82 vs 1). Accelerometer's advantage is ads (none vs shown). On price and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Accelerometer sells 1 one-off in-app purchase. Seismometer+ asks for nothing beyond the download.
Seismometer+ holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Seismometer+ has 82 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 54% of Accelerometer's written reviews are positive against 67% of Seismometer+'s.
