Perdisco uses a smart algorithm based on the ‘forgetting curve’, which hypothesizes the decline of memory retention in time. When you make a mistake, the training tool repeats the question at the right time until you remember.

The gamification elements within Perdisco, like positive feedback, keep you motivated and improve your skills in a playful manner.

Perdisco is a digital tool and platform to help you perform better in both subjects. Perdisco is co-developed by a teacher of Ancient Latin & Greek with a MA degree. The tests and exercises are checked, accurate and consist of the necessary learning material used by most schools.…

Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.

App Store

Version 1.1.8 · 2026-09-09
Your progress finally has a home. • Accounts. Create one with just your email address, or sign in with Apple or Google. Your XP, your trophies and your groups are stored safely and come back when you reinstall Perdisco or move to a new iPhone. • No account required. Perdisco stays completely usable without one — an account only makes your progress recoverable, and you are never forced into one. • Already been practising? Your existing progress is carried over to your new account, so nothing is lost. • Fixed: sound effects did not play on iPhone. They work again. • Various fixes to signing in, the dashboard and the group overview.

Method and limits

What this report can and cannot show

What a missing label means

Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.

Limits of this report

  • A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
  • Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
  • Not assessed is a state. It is never a zero and never a pass.
  • A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A human review gives an app hands-on, recorded measurements. None has been run for this app. Hands-on inspections are not yet open.
