# Part 107 vs PSI Prep App

The clearest difference is ads: PSI Prep App at none against Part 107's shown. Part 107's advantage is ratings volume (1.1K vs 281). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. Part 107 sells 10 in-app purchases, starting at $2.99 per 7 days and PSI Prep App sells 7 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.

PSI Prep App holds the better App Store score, 4.8 against 4.6. Both are backed by a comparable volume of ratings — 1.1K and 281 respectively. Written reviews complicate that: 26% of Part 107's written reviews are positive against 20% of PSI Prep App's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 5 weeks. The most recent releases landed on November 7, 2026 and November 9, 2026 respectively.
