Common issues

Troubleshooting.

These checks can help with common app issues. If they don’t resolve it, contact us before deleting app data.

The app isn’t loading

Confirm your device is running iOS or iPadOS 18.6 or later and that you have the current PeptideCalc build. Try force closing the app and reopening it.

A calculation looks different than expected

Double-check your input values and units. Make sure you’ve selected the correct syringe type. The calculator uses the values you enter and does not choose an appropriate dose or preparation method.

My saved protocols aren’t showing

Do not delete or reinstall the app while records are missing, because local-only data can be removed with the app. Check active and archived filters, review your iCloud Sync state, restart the device, and export or back up the data if possible. If the records are still missing, contact support before taking any destructive step.

I need help with an App Store purchase
