# ScreenZen vs StudyFoc.us

The clearest difference is in-app purchases: StudyFoc.us at none against ScreenZen's 4. StudyFoc.us also leads on update cadence (every 6 days vs every 3 weeks). ScreenZen's advantage is ratings volume (53K vs 2) and chart position (#160 vs unranked). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. ScreenZen sells 4 one-off in-app purchases. StudyFoc.us asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for ScreenZen against 5.0 for StudyFoc.us. That said, the two scores are not equally well evidenced: ScreenZen has 53K ratings behind it against 2, so its average is the more settled of the two. Written reviews are what separate them: 93% of ScreenZen's written reviews are positive against 100% of StudyFoc.us's.

ScreenZen ships an update every 3 weeks, StudyFoc.us every 6 days. The most recent releases landed on November 8, 2026 and November 5, 2026 respectively.
