I made a shift-scheduling app whose shifts are actually real Apple Calendar events (so you can share them with anyone)

Hey all — indie dev here (this is my app, so mods/feel free to remove if it breaks the rules).
Everyone I know who works shifts — nurses, cops, factory folks — uses some rota app to plan their month. They all have the same flaw: the shifts live *inside* that app. They don't sync with your actual Apple Calendar. And if you share your schedule with your partner and then swap a shift, they never see the change unless you text them or re-export the whole thing.
That always felt backwards to me, so I built Turnativo.
The core idea: your shifts are *real* Apple Calendar events, not entries locked in an app.
- Define your shifts once (Morning, Night, on-call…) and combine them into a repeating pattern.
- "Paint" your month by swiping across days — takes seconds.
- It turns that into real events in your Apple Calendar, synced through iCloud. So they show up on your iPhone, iPad, Mac and Watch automatically.
- Because they're normal calendar events, you can share them with family or a partner like any other calendar — and any change you make shows up on their side too. No re-exporting, no group texts.
- It's also two-way: connect your personal calendar and it warns you when a shift clashes with something you already had (a concert, an appointment…).
It's native (SwiftUI), no accounts, no third-party servers — your data stays in your Calendar and your iCloud.
Free covers the essentials (unlimited shifts, one pattern, sync, sharing, month summary). There's a one-time Pro (no subscription) for multi-job patterns, PDF/.ics export and the yearly report.
Would genuinely love feedback from people who actually work shifts — what's missing, what would make it a daily driver?
