Below you find problems and issues only applicable for IOS.
Location Services
Users of LocaToWeb will after install or after an IOS upgrade be asked for permission to use Location Services when starting a track. It should be set to "Always allow".
If set to "when app in use" the app will not have access to the GPS when the screen is off, and the tracking won't work.
Verify this setting in: Settings > Privacy > Location Services
Enable Background App Refresh
LocaToWeb needs to be allowed to run in the background. If not, the tracking will stop when the screen goes to sleep. If you have disabled "Background App Refresh" on your phone it has to be turned on again (at least for LocaToWeb).
Step 1: Launch Settings app → General.
Step 2: Tap on Background App Refresh.
Step 3: Now toggle On the switch next to Background App Refresh, or only for LocaToWeb in the list below.
Position not updating, accuracy stuck on 35m or higher
When an iPhone's location accuracy is consistently stuck at exactly 35m your phone is using Wi-Fi or cellular triangulation to guess your location instead of active GPS. This typically happens indoors, with a blocked GPS view, or when a specific permission/hardware feature is off.
1. Enable "Precise Location"
2. Check System Location Services
Your iPhone needs a few specific built-in services turned on to grab a true GPS lock.
3. Turn ON Wi-Fi
Even if you are not connected to an active wireless network, having Wi-Fi enabled allows your iPhone to "scan" nearby networks and compare them to Apple's location databases. This heavily assists in narrowing down your exact location.
4. Reset Location & Privacy
If a software glitch is causing the stuck reading, resetting location settings will wipe out corrupted caches without deleting your data.
5. Step Outside
If you are indoors, thick walls and roofs will block satellite signals. Stand outside with an open view of the sky for 30 to 60 seconds so your phone can establish a fresh, direct link with GPS satellites.
If the 35m accuracy remains even after going outside and checking your settings, there might be a physical hardware issue with your iPhone's GPS antenna.
