# Sumizeit vs ThinkBetter

The clearest difference is update cadence: Sumizeit at every 3 days against ThinkBetter's monthly. Sumizeit also leads on ratings volume (281 vs 6) and rating (4.5 vs 4.3). ThinkBetter's advantage is review sentiment (100% vs 78%). 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 ThinkBetter sells 9 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Sumizeit holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: Sumizeit has 281 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 78% of Sumizeit's written reviews are positive against 100% of ThinkBetter's, so the app with the better star average is not the one people write more warmly about.

Sumizeit ships an update every 3 days, ThinkBetter monthly. The most recent releases landed on September 23, 2026 and September 21, 2026 respectively.
