- Check matrix, vector, complex, statistics and numerical-calculus tools.
- Check invalid domains, non-convergence and offline behavior.
Data removal
Clearing app storage or uninstalling removes private calculation data and settings. Google controls retention of purchase records. A verified purchase can be restored through Google Play once commercial purchasing is configured.
Joining a test
Testing invitations and opt-in links will be supplied once a Google Play testing track is available. This page does not enroll you in a test. Report your experience honestly; no positive review is required.
