What's New in Fold Counter

1.3.2

November 12, 2026

New: Fold Counter now speaks French, Italian, Spanish, Portuguese and Korean. • Large Home Screen widget: today, the last 7 days, your streak, totals and hinge life at a glance. • Step-by-step guide for the Shortcuts automation (iOS 27.2) that counts every fold while the app is closed – no GPS, no extra battery. • More accurate counting: no extra fold when opening the app, no double counts when the automation runs late. • Folds counted by the automation now get a place on the map. • The GPS background mode is gone: the Shortcuts automation does the job better, without the location indicator.

Leider zählt da nichts

Kurzbefehle bekomme ich nicht hin, und die App selbst zählt nichts, obwohl sie im Hintergrund geöffnet ist

Not working

Some times counts no folds and has counted 300 this morning!!

Response from developer

Sorry about that – 300 folds in one morning is clearly wrong. This comes from "Count in background (GPS)": it uses the compass sensor, and magnets nearby (cases, car mounts, MagSafe chargers) can trigger it again and again. Please turn that option off in Settings and use the Shortcuts automation instead – it counts every real fold with the app closed, without GPS: Shortcuts → Automation → + → "Opened or Closed" → "When iPhone is Closed" → tap Search at the bottom → "Fold Counter" → "Count Fold" → back. Guide with screenshots: duofoldcounter.vercel.app/setup. You can delete the wrong entries in History by swiping left. The next update (1.3.1, already in review with Apple) ignores the sensor automatically as soon as the automation runs, so this can no longer happen. If anything is still off, please write to the support address on the website – I answer every mail.

Got it to work with developer’s shortcut instructions.

The app has great potential and was double counting my iPhone Duo folds at first. I reviewed the developer’s instructions on shortcut creation and automation when the app is closed and it now works for me. I have a widget on the home screen showing the count. I’m looking forward to the newer version as it seems to count a fold when I open the app. As long as I just look at the widget it is working correctly. You can always go into history and delete erroneously counted folds. Overall, I think the app is useful with the developer’s helpful instructions provided in the FAQ Help section.

Response from developer

Thank you for giving it a second chance and for the fair review! Good news: the next version (1.3.1) is already in review with Apple. It refreshes the widget right after every automation run, ignores the background sensor once your automation is active (no more double counts), and adds a large Home Screen widget with your week, streak and totals. Opening the app does not add a fold if the automation already counted it – if you still see that after the update, please let me know via the support address on the website.
