Enter the points
Name the assessment and type the total. That's the setup.
Every point. Every grade. Instantly.

// FAQ
Straight answers, before the bell rings.
The practical details teachers ask first.
Is it really a one-time purchase?
Yes. GradeKey Pro is a single $4.99 in-app purchase. There's no subscription and nothing renews.
What do I get for free?
One saved assessment with full access to the conversion table, three-way lookup, every grading scale, custom tiers, extra credit, and iCloud sync. Pro adds unlimited assessments, PDF/CSV export, and folders.
Does it work on iPad?
Yes — GradeKey is universal, with a split-view layout on iPad.
Do you collect any of my data?
No. Nothing. Your assessments stay on your device and, if you enable it, sync through your own private iCloud. There's no account, no analytics, and no tracking.
Can I use my school's grading scale?
Yes. Pick one of eight presets or build your own — rename tiers, add or remove them, set any percentage cutoff, and choose where the passing line falls.
How does extra credit work?
Enter a bonus value and the table extends above 100%, marking those rows "EC".
Grading is hard enough. The math shouldn't be.
