PRACTISE AND LEARN
The trainer starts with worked examples, hides steps one by one and finally lets you calculate on your own. In chart tasks you choose the right chart and assess it. A true-or-false trainer checks your understanding with the reason, and the practice exam can follow the layout of a real exam. Hints help in levels, and typical mistakes are named instead of just marked wrong. The app spaces repetitions with FSRS, and the study plan spreads the material backwards from your exam date. Your progress shows what you have covered and how well you know it. If you like, the solution path also shows the key sequence for your calculator. An optional study reminder (at most one a day) keeps you on track.

FREE AND PRO
Free: every calculator with result and formula, one worked example per method with the complete solution path, the trainer's model solutions and the progress overview.
Pro: complete solution path for your own numbers, trainer levels 2 to 4 with generated problems and error diagnosis, exam mode, repetition with FSRS, daily plan and study plan, exam readiness and export of the solution path as PDF. Pro keeps growing: we keep adding new problems and further modules.

Pro is available as a monthly, a semester (6 months) and a yearly subscription. The monthly subscription starts with a 7 days trial if you have not used it before. The store shows price and term before you buy. The subscription renews automatically unless you cancel at least 24 hours before it ends. You can manage and cancel it any time in the Google Play Store under Subscriptions.

Recent changes:
New: true or false on every topic page. Today, Topics and Progress say whether “secure” refers to today or to exam day. The study plan works out more precisely how much extra study time per day you need to fit in all the material. The mock exam spreads its tasks more evenly across the modules. Whole-number exponents are set as superscripts, and with a large system font, titles and solution steps wrap cleanly. Your learning progress is kept.
