SnapperMapper is free, and support is a one-person effort. Please read this page first. Nearly everything people write in about is answered somewhere below, and you'll have it fixed in a minute rather than a day.
If that doesn't sort it, do get in touch: [email protected]. Tell me your iPhone model and iOS version, and what you expected to happen. That usually gets to the answer in one reply. I read everything and will help where I can, though I can't promise a response time.
Some of my photos didn't appear on the map
SnapperMapper can only draw a photo it knows the location of. A photo is skipped when:
- It has no location. Photos taken with Location Services off for the Camera, screenshots, saved images, and most photos received in messages carry no coordinates. The import result screen counts these separately so you can see how many there were.
- It falls outside the date range you chose, or outside it once its true local timezone is resolved.
- You hid it, in review or in the Snap Library. Hidden snaps can be restored at any time from the Snap Library.
- It was already imported. Overlapping imports never duplicate a photo.
- Limited Access is on and the photo isn't among the ones you selected. Settings shows how to grant Full Access if you'd prefer.
A date or time looks wrong
Photos are filed by the local day where they were taken, not by your phone's current timezone. A photo taken at 11pm in Tokyo belongs to the Tokyo day even if you're home in Europe when you import it.
Working out that timezone needs a network connection. Until it completes, the app marks affected dates as estimates and says so on the day header. Open the app on Wi-Fi for a while and it will finish and re-file anything that moved.
Place names are missing or say "offline"
A new place needs one successful Apple Maps lookup before SnapperMapper knows its name. Open the app with a connection and leave the trip visible while it finishes. After a name has resolved, SnapperMapper stores that last-known name in its protected local database so it remains available after relaunch and offline. See the privacy policy for exactly what is and is not retained.
What do Keep, Favorite, and Hide actually do?
- Keep: the normal choice. The snap stays on the map.
- Favorite: a highlight. Favorites can be filtered on the timeline, exported on their own, and synced to a Photos album.
- Hide: for duplicates and photos unrelated to the day. It removes the snap from the map only inside SnapperMapper.
None of the three ever edits or deletes the original photo. Every decision is reversible from the Snap Library, for as long as you keep the trip.
The route looks wrong, or has gaps
The route is reconstructed from where your photos were taken, so it is only ever as detailed as your photography. Stretches you didn't photograph are drawn as brass dots rather than guessed at. The app will not invent a path it has no evidence for.
GPS drift is smoothed automatically. If a single wildly wrong coordinate is distorting a day, hiding that one snap usually fixes it.
Album sync
Syncing a trip album creates or updates a Photos album so that it contains exactly your current picks, adding what's missing and removing what no longer qualifies. It changes album membership only and never deletes a photo from your library. It needs Full Photos Access; under Limited Access every other feature still works.
Getting the introduction back
The Getting Started guide is always available from Settings, whether or not you've seen it before.
Deleting your data
All SnapperMapper data lives on your device. Deleting a trip removes it and its days; deleting the app removes everything. Neither touches your Photos library.
Still stuck?
Email [email protected]. Bug reports, feature requests, and "this map is wrong and here's why" are all welcome.
Postal contact and provider information are available in the contact and legal notice.
A fair warning, kindly meant: this is a free app maintained by one person in their own time, so support is limited to what I can realistically handle. If you've worked through the answers above and something is still wrong, write in. I'll get to it in a reasonable time and do my best to help.
