# Schluter® vs Flexblocks

The clearest difference is review sentiment: Flexblocks at 100% against Schluter®'s 26%. Flexblocks also leads on update cadence (every 10 days vs every 2 months). Schluter®'s advantage is rating (4.7 vs 1.0) and in-app purchases (none vs 3). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. Flexblocks sells 3 in-app purchases, starting at $3.99 per month. Schluter® asks for nothing beyond the download.

Schluter® holds the better App Store score, 4.7 against 1.0. That said, the two scores are not equally well evidenced: Schluter® has 571 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 26% of Schluter®'s written reviews are positive against 100% of Flexblocks's, so the app with the better star average is not the one people write more warmly about.

Schluter® ships an update every 2 months, Flexblocks every 10 days. The most recent releases landed on September 24, 2026 and June 7, 2026 respectively.
