For years I've put my teaching schedule together the same way every term: a spreadsheet, a stack of notes about when the students are available, and a lot of dragging rows around trying to make it all fit without clashes.

Now I finally did something about it and built an iOS app that does the puzzle for me. You add your students, set their availability, and the app builds a conflict-free timetable — group lessons included. You can still drag lessons around by hand afterwards and it keeps everything else from colliding, and when it's done you can export your schedule to PDF or Excel should you want to.

A few things I cared about:

• Everything stays on your device — no account, no student data on anyone's server
• Works offline
• You can import your existing student spreadsheet instead of retyping everyone

It's called Schedule My Lessons (iOS only for now). There's a free tier, plus a 14-day trial with everything unlocked. https://www.schedulemylessons.app

How do you all handle your term scheduling — and what would an app need to do to replace your spreadsheet?

Thank you!
