Souki - Paper Workbook Review
Spaced repetition planner
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Souki is a review planner for paper workbooks, textbooks and past exams.
You don't type in questions or take photos. Just register which book, which page, which number - and Souki schedules the next review automatically based on how well you did.
WHO IT'S FOR
- Professionals working through certification workbooks
- Students preparing for entrance exams with past papers
- Anyone memorizing with paper vocabulary books
HOW IT WORKS
1. Register your materials and problem numbers (add ranges like 1-30 in one go)
2. Solve today's problems on paper
3. Rate each one: Again / Hard / Good / Easy
The better you remember, the longer the gap until the next review (spaced repetition). Only today's problems show up, so you never wonder what to study.
MADE FOR PAPER
- Page-order sessions: minimal page flipping
- Set an exam date and reviews never get scheduled past it
- Track why you got it wrong (careless mistake, not memorized...) and analyze weak spots
- Home Screen widget shows what's left today
FREE
- Up to 3 books / unlimited problems and reviews
- Range input, exam dates, reminders, widget, backup
PREMIUM (monthly / yearly / lifetime)
- Unlimited books, search & filters, tags, full statistics, CSV import, iCloud sync, alternate app icons
Redoing problems is where learning happens. Souki handles all the scheduling.
