# Formalize vs Flexblocks

The clearest difference is review sentiment: Flexblocks at 100% against Formalize's 25%. Flexblocks also leads on price (Free vs $1.99) and update cadence (every 10 days vs every 9 months). Formalize's advantage is rating (2.6 vs 1.0) and in-app purchases (none vs 3). On device support there is nothing between them.

Flexblocks is free to download; Formalize costs $1.99 up front. Flexblocks sells 3 in-app purchases, starting at $3.99 per month. Formalize asks for nothing beyond the download.

Formalize holds the better App Store score, 2.6 against 1.0. That said, the two scores are not equally well evidenced: Formalize has 10 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 25% of Formalize'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.

Formalize ships an update every 9 months, Flexblocks every 10 days. The most recent releases landed on September 14, 2026 and June 7, 2026 respectively.
