# Harmonium vs StudyPrime

The clearest difference is review sentiment: StudyPrime at 100% against Harmonium's 21%. StudyPrime also leads on rating (5.0 vs 2.5) and ads (none vs shown). Harmonium's advantage is ratings volume (30 vs 5) and iOS requirement (13.0 vs 17.0). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Harmonium sells 3 in-app purchases, starting at $2.99 per 7 days and StudyPrime sells 4 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.

StudyPrime holds the better App Store score, 5.0 against 2.5. That said, the two scores are not equally well evidenced: Harmonium has 30 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 21% of Harmonium's written reviews are positive against 100% of StudyPrime's.

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on November 3, 2026 and October 31, 2026 respectively.
