# Penseum vs Keepmind

The clearest difference is rating: Keepmind at 4.8 against Penseum's 3.2. Keepmind also leads on update cadence (weekly vs every 8 months) and monetization model (free vs freemium). Penseum's advantage is review sentiment (60% vs 50%). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Penseum sells 2 in-app purchases, starting at $29.99 per month and Keepmind sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Keepmind holds the better App Store score, 4.8 against 3.2. Both are backed by a comparable volume of ratings — 9 and 19 respectively. Written reviews complicate that: 60% of Penseum's written reviews are positive against 50% of Keepmind's, so the app with the better star average is not the one people write more warmly about.

Penseum ships an update every 8 months, Keepmind weekly. The most recent releases landed on November 8, 2026 and October 30, 2026 respectively.
