# IMAIOS e vs StudyMyTremor

The clearest difference is price: IMAIOS e at Free against StudyMyTremor's $3.99. IMAIOS e also leads on rating (4.9 vs 3.2) and update cadence (every 9 days vs every 12 months). StudyMyTremor's advantage is in-app purchases (none vs 2) and review sentiment (67% vs 48%). On ads and device support there is nothing between them.

IMAIOS e is free to download; StudyMyTremor costs $3.99 up front. IMAIOS e sells 2 in-app purchases, starting at $21.99 per month. StudyMyTremor asks for nothing beyond the download.

IMAIOS e holds the better App Store score, 4.9 against 3.2. That said, the two scores are not equally well evidenced: IMAIOS e has 1.4K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 48% of IMAIOS e's written reviews are positive against 67% of StudyMyTremor's, so the app with the better star average is not the one people write more warmly about.

IMAIOS e ships an update every 9 days, StudyMyTremor every 12 months. The most recent releases landed on October 27, 2026 and October 26, 2026 respectively.
