Move your weight history to Downtrend
You do not have to start your weight history again when you switch apps. Downtrend can read CSV exports from the six apps below. Choose your app, get the right file, then check the preview before importing.
Already have a file? Go straight to Import your file. Have a Downtrend backup? Use Restore a Downtrend backup instead.
Choose your app
- Happy Scale
- Samsung Health
- openScale 3.x
- Better Weight by Habitics
- WeightFit
- Weight Tracker
- Excel, Google Sheets or another CSV
- Libra
- Renpho, Google Fit or another app
These instructions reflect the formats we have tested as of 24 October 2026. Export menus and file formats can change between app versions. Keep your original file and your old app until you have checked the imported history.
Happy Scale
Use Export as CSV in Happy Scale and save the resulting file to your Android phone. Our tested export was named weights.csv, from Happy Scale 2026.7.
The file does not identify its weight unit. In Downtrend, choose the unit used for the export, kilograms or pounds. Check a familiar reading before confirming. Happy Scale’s moving average is not imported. Downtrend calculates its own trend from your weigh-ins, so the curves may differ.
Use the CSV for this route, not a .HappyScale complete backup. Continue to import.
Samsung Health
In Samsung Health, open More options → Settings → Download personal data, then choose Download. Follow the sign-in prompts. Samsung places the downloaded files in the Samsung Health folder under Downloads.
Find the weight CSV whose name starts with com.samsung.health.weight. Select that file in Downtrend, not the whole folder, an archive or a different health record. This imports weight history, not your steps, workouts or complete Samsung Health account.
Continue to import. See Samsung’s download instructions if the download step looks different on your phone.
openScale 3.x
Export your measurements as CSV from openScale and move the file to the phone running Downtrend. Choose the export for the person whose history you want to import. Our tests cover exports from openScale 3.x, including 3.1.3.
Downtrend reads weights and supported tape measurements from this format. It does not reproduce every body composition field that openScale can store. openScale 2.x exports have not been verified.
Better Weight by Habitics
Export your history as CSV from Better Weight. Our tested file was named better_weight_export_2026_09_20.csv. Downtrend may label the source Habitics in its import preview.
The tested exports use kilograms or pounds. With stones selected in the source app, our captured export still contained pounds. Check the unit and a known weight in the preview rather than assuming the file uses the unit shown on your old chart.
WeightFit
Export your history as CSV from WeightFit, then save the file on your Downtrend phone. The tested format includes Date, Weight, Tags and Note columns. Downtrend reads the dates, weights and notes. Do not expect tags to transfer.
Weight Tracker
Use Weight Tracker’s CSV export. Our tested file was saved under Downloads → Weight Tracker and contained a Date (YYYY-MM-DD) column and a weight column.
Several apps use similar names. If your file looks different, treat it as an unverified CSV. Body fat and muscle mass percentages in this export are not imported.
A spreadsheet or another CSV
Export the sheet containing your weigh-ins as CSV UTF-8. An Excel workbook, PDF, screenshot or chart image is not a CSV. Renaming its extension will not convert it.
Use one row per weigh-in, with a date column and a numeric weight column. Dates such as 2026-10-24 avoid confusion between day and month. Keep weights in one unit and put notes in their own column. Save a copy before changing the sheet.
Downtrend tries to identify the columns. If it does not, use Choose the columns yourself and map Date and Weight, plus Time and Note if available. Other CSV formats may work, but are not guaranteed to. Continue to import.
Libra
We do not currently offer a verified Libra migration route. We have not confirmed an accessible export path in the version we checked, and Downtrend has no tested Libra import preset. That does not mean every Libra version lacks export.
If you already have an old CSV export, keep it. You can try the CSV route, but only confirm the import if the dates, units and readings are correct. If you cannot export, you can start logging in Downtrend now and keep Libra for your earlier history, or enter selected older readings manually.
Other apps
Renpho, Google Fit and other unlisted apps do not have verified import presets in Downtrend. If your app provides a CSV with dates and weights, try the CSV route. An account backup or archive is not necessarily a readable weight table.
Downtrend does not currently import through Health Connect. There is no need to connect your old account to Downtrend for a file import.
Import your file
- Save the CSV on the phone running Downtrend.
- During setup, tap Import or restore → Import weight history. If you have finished setup, open Settings → Data → Import. If a previous import is shown, choose Choose a file.
- Select the CSV. Check the detected source, date range and sample readings.
- Choose the weight unit if asked. If the dates could mean either day first or month first, select the correct order. Review any skipped rows or duplicates.
- Confirm the import only when the preview matches your records. Then compare a few older and recent readings with your original app.
Importing history does not transfer another app’s account, goals, reminders or settings. Complete Downtrend’s setup after importing if you are new to the app.
Made a mistake? Tap Undo on the confirmation, or open Settings → Data → Import → Undo the last import. Entries you have edited since importing are kept. Check the result before importing another file.
Restore a Downtrend backup
For a backup created by Downtrend, use Restore a Downtrend backup during setup, or Settings → Data → Restore from backup afterwards. A CSV export is not a full backup.
Read the restore choice carefully. Add what’s missing keeps existing records. Replace with the backup removes records on this phone that are not in the backup, and cannot be undone.
If a file will not import
Check that you selected a text CSV, not a workbook or archive. Check the mapped columns, date order and units. The preview explains rows it leaves out, including duplicates, unreadable values and future dates. Avoid repeatedly changing the original file to make it fit.
If you still need help, contact us with the app name, version and error message. You do not need to send your full health history. Start with column headings and a description of the problem.
