# Thortspace vs Flexblocks

The clearest difference is review sentiment: Flexblocks at 100% against Thortspace's 40%. Thortspace's advantage is rating (3.5 vs 1.0) and ads (none vs shown). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Thortspace sells 1 one-off in-app purchase and Flexblocks sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Thortspace holds the better App Store score, 3.5 against 1.0. Both are backed by a comparable volume of ratings — 4 and 1 respectively. Written reviews complicate that: 40% of Thortspace'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.

Thortspace ships an update weekly, Flexblocks every 10 days. The most recent releases landed on September 15, 2026 and June 7, 2026 respectively.
