Read full descriptionHide full description
Stop spending your study time planning your study time. Add your fixed commitments - classes, club activities, cram school, part-time shifts - and the tasks you want to get done. The app works out the time you have left and places your study tasks into the gaps. WHO IT IS FOR - You lose time to planning every single week - Your plans fall apart after three days - You find it hard to work backwards from a deadline - Short gaps between commitments go to waste WHAT IT DOES Build a timetable just by adding your schedule Add recurring commitments once and reuse them every week. Whatever is left over is counted automatically as time you can study in. Place tasks automatically Add a task like "Vocabulary, 30 min" or "Maths problems, 2 hours" and the app fits it into your free slots. Long tasks are split up, with breaks in between. Work backwards from deadlines Tasks with deadlines are placed in order of urgency. If something will not fit before its deadline, you find out while there is still time to act. Avoid overloading yourself Your available time and your total task time are shown side by side, with a warning when you have taken on more than fits. See the whole week at a glance Your commitments and study tasks laid out as a timetable. Drag anything to adjust it by hand. Get told what you did not finish An end-of-day notification lists the tasks you did not complete, so they can be rescheduled. Track your study (Premium) Charts for study time over time, a breakdown by subject, and your current streak. PRICING Everything central to the app is free. Premium removes ads and unlocks study statistics and longer automatic scheduling. - Premium (Monthly) - Premium (Yearly) Subscriptions renew automatically. Unless cancelled at least 24 hours before the end of the current period, they renew for the same period at the same price. You can cancel any time from your App Store account settings. YOUR DATA Your schedule, tasks and records are stored only on your device. No account is required.

Verdict
The clearest difference is in-app purchases: PIECE at none against Auto Study Planner's 2. PIECE also leads on ads (none vs shown) and update cadence (every 3 days vs every 3 weeks). Auto Study Planner's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price there is nothing between them.
