# phase6 vs sofatutor

The clearest difference is rating: phase6 at 4.5 against sofatutor's 4.2. On price, review sentiment, ratings volume and update cadence there is nothing between them.

Both are free to download. phase6 sells 62 in-app purchases, starting at $6.99 per 3 months and sofatutor sells 5 in-app purchases, starting at $39.99 per month. Whichever you choose, the download price is not the number that matters.

phase6 holds the better App Store score, 4.5 against 4.2. Both are backed by a comparable volume of ratings — 204 and 136 respectively. Written reviews complicate that: 74% of phase6's written reviews are positive against 80% of sofatutor's, so the app with the better star average is not the one people write more warmly about.

phase6 ships an update every 3 weeks, sofatutor every 6 weeks. The most recent releases landed on September 24, 2026 and September 23, 2026 respectively.
