Get Castmo on your iPhone
Castmo requires iOS 26 or later. Install Apple's TestFlight app, then open the Castmo invitation on your iPhone and follow Apple's installation steps. No Castmo account is required.
The official release is awaiting App Store review. Join the public TestFlight beta while you wait.
Voice input and automatic fields
Tap the voice-input button on Home and describe your catch. Text appears as you speak. Tap Done once, then take a photo to save the catch. Open the record later to correct details or add photos.
If voice input is unavailable, check microphone permission in iOS Settings and prepare Apple's speech resources in Castmo's Apple Intelligence settings while online. Resources and supported languages depend on your device and system.
Clear details can still be filled by local rules when Apple's text model is unavailable. Complex interpretation and social captions require available Apple Intelligence; you can always review and edit saved fields manually.
Weather and fishing spots
The top of Home shows conditions for your current location. Pull down the dashboard handle to see more weather information. Enable location permission and network access for current conditions and place names.
Catches with saved coordinates appear on your map. A record saved without a location will not have a map pin. The map is your own catch history, not a public catalogue of fishing spots. A weather-service interruption does not require deleting your records.
Photos, editing and sharing
Taking the first catch photo saves the record. To add more images or correct fields, open that catch and choose Edit. Photo editing includes cropping, text, logo stickers and mosaic; preview before saving or sharing.
If saving an edited image fails, check available device storage and Photos permission in iOS Settings. Social captions can be edited and copied before you post them. Castmo does not automatically publish to social platforms.
Protect or delete your journal
Export important records and save photos you want to keep. Castmo does not provide cloud backup or cross-device sync, and we cannot restore a journal from our servers.
To remove personal app data, open Settings → Privacy & Data and follow the deletion confirmations. This does not remove images already saved to Photos or content already shared with other apps. Do not uninstall the app as a troubleshooting step unless you have copies of the records you need.
Talk to us
Email orion.hengxing@gmail.com for help, privacy requests or suggestions. Include your iPhone model, iOS version, Castmo version and the steps to reproduce the issue. A screenshot can help; remove private locations, faces and other sensitive details first.
Beta testers can also open TestFlight → Castmo → Send Beta Feedback. Apple shares that feedback with us. We cannot promise a fixed response time, but a clear description helps us investigate.
