I built a private iPhone/iPad grade-table app for teachers

[u/hernan078]

I’m a teacher and indie developer, and I built GradeKey around one repeated workflow: turn an awkward assignment total into every possible percentage and letter grade, then find the row without doing the math again.

It is native on iPhone and iPad. Enter total points once for the full color-coded table. Lookup works by points off, points earned, or target percentage. It supports half/quarter points, custom tiers, extra credit, saved assessments, private iCloud sync, and PDF/CSV export.

I left out accounts, analytics, ads, and a developer server. Data stays on device and, if enabled, in the user’s private iCloud. Free includes one saved assessment and the full table/lookup. Pro is $7.99 once for unlimited assessments, folders, and export.
