Skip the big apps. Use Apple Notes plus folders and smart folders.
Set up 3 main folders: Inbox, Projects, Archive.
Dump every new note in Inbox. Once a day, move notes to Projects or Archive.
Use simple tags in titles, like “Math – Algebra – Fractions”. Search stays fast.
Add checklists for tasks. Add photos for class boards.
Sync stays free on all Apple devices.
No logins, no ads, low friction.
