Q1. Why am I being asked to upgrade Sync and Backup?
We’re upgrading the system that powers LogTen’s sync and backup. Moving to the new system gives us a stronger foundation for ongoing improvements to sync and backup speed and reliability.
Q2. Do I have to upgrade now, and what happens if I don’t?
We recommend upgrading as soon as possible. The previous sync and backup system is being retired.
Your existing cloud backups and the logbook on each device stay safely stored either way. But once the previous system is retired, versions earlier than 2026.2 can no longer sync between devices or create new cloud backups. Updating every device to 2026.2 or higher restores syncing and backup.
Please update to 2026.2 (or higher) on all your LogTen devices as soon as you can:
Q3. What do I need to do to upgrade?
Update LogTen to version 2026.2 or later on every device where you have it installed.
When the prompt to upgrade Sync and Backup appears on your device, tap ‘Start Upgrade’.
On any device you add after the first one, the prompt you see will say ‘Continue’ instead.
LogTen backs up and upgrades your data automatically and shows your progress until it’s complete. Please make sure to keep LogTen open and do not leave the backup screen until the upgrade is complete. For most logbooks this takes less than a minute.
Q4. Is my data safe?
Yes. The new sync and backup is designed to carry your existing logbook forward exactly as it is. It includes integrity checks, a full backup before any device connects to the new system, and a safety rollback if something doesn’t look right. When you upgrade each device, LogTen finds any new logbook entries or entry updates in its local logbook that haven’t synced yet and reconciles them into the new system.
Q5. Do all my devices need to be on version 2026.2 or higher?
Yes. Every device running LogTen needs to be updated to version 2026.2 or higher:
Devices on earlier versions won’t sync with devices that have already upgraded. Each device keeps its own data, so nothing is lost, but new changes won’t be exchanged between devices until every device is upgraded. When the prompt to upgrade appears on LogTen will compare that device’s data against your account and confirm everything before it connects to the new system.
Q6. I use LogTen on more than one device. Does the order matter?
No, the order doesn’t matter. However we recommend you Update and Upgrade every device you use with LogTen to the new system as soon as possible. Each device brings any new or updated entries local to that device into the new system when you upgrade. Once all your devices are upgraded, they’ll sync with each other again as usual.
Q7. How long does the upgrade take?
It depends on the size of your logbook and your network connection. LogTen shows live progress the whole time and completes the upgrade without any extra steps from you.
Most logbooks upgrade in under a minute. Larger logbooks (several thousand flights) take longer, because a full copy of your logbook is backed up before the upgrade begins.
NOTAM: Keep LogTen open and stay on the upgrade screen until it’s finished.
Q8. Syncing looks stuck. Should I reinstall LogTen or sign out?
STOP! Deleting and reinstalling LogTen, or signing out, is not the way to fix a sync issue, and it can remove data that the upgrade would otherwise recover for you.
Your logbook lives on your device, and it stays safe there even while syncing is interrupted. In almost every case the fix is simply to update to version 2026.2 or higher and run the upgrade when prompted, which brings your data across for you. If something still doesn’t look right, contact support (see below) and we’ll help.
Q9. I’m seeing a “Startup Failed” message or a loading screen that won’t finish when I open LogTen. What do I do?
STOP! Your data is safe on your device. Contact support (see below) and we’ll get your device connected to the new sync and backup system, and up and running again.
Q10. I have a very large logbook. Is a long upgrade or a big list of changes normal?
Yes. Large logbooks take longer to back up and upgrade, and you may briefly see a summary with large counts as LogTen confirms everything is accounted for. That’s the upgrade working as intended, not an error. Keep LogTen open on the upgrade screen and in the foreground until it finishes.
Q11. I need help!
