Backup / Restore

Frequently asked questions
Read all 50 questionsWhat can I use for free?
You can log basic measurements such as weight, reps and time, record each side separately, view your history and use basic analysis. There is no limit on the number of exercises or routines you create. Exporting records, backups and restoring backups are also free.
Creating your own custom fields and setting up gyms and machines requires Pro or Lifetime. You can try these features free for the first 14 days.
What is the difference between Pro and Lifetime?
They include the same features. Pro is a monthly or yearly subscription. Lifetime is a one-time purchase. Both include custom fields, gym and machine settings, and unlimited Bridge imports. Prices are shown on the purchase screen in the app.
Will I be charged automatically when the free trial ends?
No. After the initial 14-day trial, you move to the free plan. You will not be charged unless you choose to purchase a paid plan. You do not need to cancel the trial.
What happens to my records and custom fields when Pro ends?
Your past records remain after your paid access ends. You can still view and export historical custom-field values and machine information, and continue logging with the free basic fields.
Creating or editing custom fields, entering or changing their values, analyzing custom fields, and setting up or selecting gyms and machines requires Pro or Lifetime.
Can I move records from my current app or spreadsheet?
To import records from another app or a spreadsheet, you must convert them to RENMA format first. The original files cannot be imported as they are. You can use an external AI to help with the conversion.
What can be transferred depends on the information in the source data. After conversion, check the contents in RENMA's preview before importing.
Where are my records stored?
Your records are stored on your smartphone. RENMA does not automatically send your workout records to a RENMA server.
To use them with an external AI or another service, you export and share the files yourself. Keep a backup outside your phone as well.
Can I transfer my records when I change phones?
Yes. Export a RENMA backup on your old phone and restore it in RENMA on your new Android phone. Before giving up the old phone, save the backup on another device or storage you control.
Pro and Lifetime purchases are restored separately from your records, using the Google account you purchased with.
Can I export my records as CSV or other files?
Yes. You can export to formats such as CSV and JSON. Even on the free plan, you can take your records with you, including previously recorded custom-field values.
Exports for spreadsheets and other services serve a different purpose from a RENMA backup. To prepare for a new phone or device failure, save a backup.
Do I need AI to log workouts or set things up?
No. You can set up exercises and routines and log every workout using RENMA alone. External AI is an optional way to convert old records or prepare settings in bulk. RENMA does not have a built-in AI chat.
Does all this customization make setup and daily logging complicated?
You can start with just the basic fields. Add other fields when you need them and save your setup in routines, ready to select next time.
While logging, you can adjust numbers with the + and − buttons beside a value, or scroll to choose a number. You do not have to type every number again with the keyboard.
Can I use RENMA without NFC tags?
Yes. You can select a routine in the app and log your workouts without NFC tags. NFC is an optional shortcut for opening a routine by holding your phone near a registered tag. The NFC feature itself is free.
Is there an iPhone version?
An iPhone version is not currently available. RENMA is being developed for Android, and the Android release is in preparation. There is no announced date for an iPhone version.
