JeKeU Support

JeKeU keeps utility data local and focused. Here are a few practical steps for the most common tasks.

About the app

Use JeKeU to manage properties, meters, tariffs, services, readings, recurring charges, and calculation history on your device.

Backup and restore

• Create a backup package from Settings → Backup & restore.
• Save the ZIP somewhere you control, such as a device folder or a provider you trust.
• To restore, choose the package and review its preview before confirming. Restore replaces the current local dataset.
• Keep the original backup file until you have confirmed that the restored data is available.

Common troubleshooting

A reading cannot be calculated

Check that the current reading, starting reading or previous reading, and applicable tariff are present. A baseline is not itself a monthly reading.

The app shows old data after a change

Return to Properties and allow the screen to reload after saving a reading, tariff, service, or backup. If the issue remains, close and reopen the app before reporting it.

A backup will not open

Use the original JeKeU ZIP or legacy JSON file. Spreadsheet files are for viewing only and cannot be restored.

Report a problem

Please include the app version, device and Android/iOS version, the screen where the issue happened, and steps to reproduce it. Do not send private meter readings or backup files unless you are comfortable sharing them.
