# Sumizeit vs KeepMind

The clearest difference is rating: KeepMind at 5.0 against Sumizeit's 4.5. KeepMind also leads on review sentiment (100% vs 78%). Sumizeit's advantage is ratings volume (282 vs 4) and update cadence (every 4 days vs fortnightly). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Sumizeit sells 19 in-app purchases, starting at $0.99 per year and KeepMind sells 4 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

KeepMind holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Sumizeit has 282 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 78% of Sumizeit's written reviews are positive against 100% of KeepMind's.

Sumizeit ships an update every 4 days, KeepMind fortnightly. The most recent releases landed on October 29, 2026 and October 8, 2026 respectively.
