Switch from Happy Scale without losing your history
Keep your Happy Scale weigh-in history when you switch.
How to export from Happy Scale
- Open Happy Scale and go to its settings.
- Choose Export Data and export your weigh-ins as a CSV.
- Share the file to yourself so you can reach it from this device.
- Upload the file from Settings, under Import your history.
- If the weight column does not say whether it is in kilograms or pounds, we ask you which.
- More than one weigh-in on a day is reduced to the latest, since a day holds one weigh-in here.
What comes across
- Every dated weigh-in
- Body fat, where the file has it
What your export cannot carry
- Happy Scale’s trend line is its own smoothing of your readings. MuscleBuddy works out its own trend from the weigh-ins, so the app’s figure is not imported.
- It is a weight history only. It carries no food and no training.
Each of these comes from the export file's own format. Anything the file does not contain is reported to you in the preview rather than filled in.
What imported data counts for
Your history, personal records, charts and analytics come with you. Ranks, XP and achievements are earned here, so imported sessions never move them.
Ranks, XP, achievements, streaks and leaderboards count only what you log here, so an imported spreadsheet can't put anyone at the top of a board. Everything that describes your training rather than scoring it, which is your history, your personal records, your charts and your analytics, uses your imported data from day one.
How the import works
Upload a CSV file and nothing is written yet. You get a preview first: how many rows of each kind, the date range they cover, which names matched automatically, and which need a decision from you.
When you approve it, the rows are written and stamped as part of that import. If a day already has an entry you made yourself, your own entry wins and the imported row is skipped, and the skip is counted and shown rather than quietly dropped.
Changed your mind? One button removes every row that import created and leaves everything else alone. You can upload the same file again months later too. Rows that already exist are skipped instead of duplicated, so you only ever gain what is new.
Your file, and how long we keep it
The uploaded file is stored privately for a short retention window so an import can be retried, then deleted. Undo keeps working after that, because it is keyed to the import rather than the file. Your account holds the data, and you can export it or delete your account at any time.
Frequently asked
- Why does the history matter?
Your calorie target adjusts to your weigh-in trend. Bringing the history in means the first adjustment is based on how your weight has actually moved, not on a blank slate.
- Can I undo an import?
Yes. Every row an import writes is stamped with that import, so one button removes all of it and leaves anything you logged yourself untouched. You can also upload the same file again later. Rows that already exist are skipped rather than duplicated.
