# Mandel vs FractalEcho

The clearest difference is rating: FractalEcho at 3.9 against Mandel's 3.2. FractalEcho also leads on update cadence (fortnightly vs every 62 months). Mandel's advantage is in-app purchases (none vs 3) and review sentiment (100% vs 80%). On price, ratings volume, ads and device support there is nothing between them.

Both are free to download. FractalEcho sells 3 in-app purchases, starting at $1.99 per month. Mandel asks for nothing beyond the download.

FractalEcho holds the better App Store score, 3.9 against 3.2. Both are backed by a comparable volume of ratings — 5 and 10 respectively. Written reviews complicate that: 100% of Mandel's written reviews are positive against 80% of FractalEcho's, so the app with the better star average is not the one people write more warmly about.

Mandel ships an update every 62 months, FractalEcho fortnightly. The most recent releases landed on November 2, 2026 and November 5, 2026 respectively.
