This is an app that allows you to record study time and check the history with pie charts and stacked bar graphs. - Counting study time The app counts. Select a subject, set the study time, and count to record study time. If you close the app or perform other operations while studying, the count will be interrupted. - Register subjects By registering subjects, you can record which subjects you studied. By recording each subject, you can understand which subjects you do not have enough study time. - Study history Displays daily study time in a stacked bar graph. Recheck your study time by looking at your past history. If you do not have enough study time, make sure to set aside time for studying. - Advertisement This app is free to use, but ads are displayed. To avoid interrupting your studies, ads are displayed only after the countdown is completed so as not to break your concentration. - Purpose of this app This app was created for children who tend to study only in the subjects they are good at. The study time for subjects you are weak at tends to be short. By visualizing the time you study, you can understand the lack of study time for subjects you are weak at. I hope this will lead to improved grades for everyone.

Verdict
The clearest difference is rating: Retime at 5.0 against Study Timer & Time Tracker's 4.2. Study Timer & Time Tracker's advantage is ratings volume (27 vs 1) and monetization model (ad-supported vs free with in-app purchases). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Study Timer & Time Tracker sells 1 one-off in-app purchase and Retime sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
Retime holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: Study Timer & Time Tracker has 27 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 85% of Study Timer & Time Tracker's written reviews are positive against 72% of Retime's, so the app with the better star average is not the one people write more warmly about.
Study Timer & Time Tracker ships an update every 4 days, Retime every 5 days. The most recent releases landed on October 13, 2026 and October 11, 2026 respectively.
