# Booster Prep vs Handpiece

The clearest difference is review sentiment: Handpiece at 100% against Booster Prep's 61%. Handpiece also leads on update cadence (daily vs fortnightly). Booster Prep's advantage is rating (4.8 vs 4.4) and ratings volume (740 vs 7). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Booster Prep sells 7 one-off in-app purchases and Handpiece sells 3 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Booster Prep holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Booster Prep has 740 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 61% of Booster Prep's written reviews are positive against 100% of Handpiece's, so the app with the better star average is not the one people write more warmly about.

Booster Prep ships an update fortnightly, Handpiece daily. The most recent releases landed on November 12, 2026 and November 10, 2026 respectively.
