# ThinkSpace vs MindFlow

The clearest difference is ads: ThinkSpace at none against MindFlow's shown. ThinkSpace also leads on update cadence (monthly vs every 17 months) and ratings volume (273 vs 33). MindFlow's advantage is review sentiment (69% vs 54%) and iOS requirement (12.0 vs 15.6). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. ThinkSpace sells 2 in-app purchases, starting at $2.99 per month and MindFlow sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.3 for ThinkSpace against 4.4 for MindFlow. That said, the two scores are not equally well evidenced: ThinkSpace has 273 ratings behind it against 33, so its average is the more settled of the two. Written reviews are what separate them: 54% of ThinkSpace's written reviews are positive against 69% of MindFlow's.

ThinkSpace ships an update monthly, MindFlow every 17 months. The most recent releases landed on September 19, 2026 and August 19, 2026 respectively.
