Open OnScale and create an account with a username, email address, and password.

Cloud sync is optional. When it is available in your version of the app, signing in lets you restore your data if you get a new device. You can still use OnScale to log locally if cloud sync is not set up.

No. Signing out does not delete your account or your logs.

If cloud sync is on, sign back in with the same account to restore your data. If you want to permanently remove your information, use Delete Account in Profile & Settings instead of signing out.

Go to Profile & Settings and choose Delete Account. Confirm when prompted.

Deleting your account removes your cloud data (if sync is enabled) and local data on that device. This cannot be undone. Signing out is not the same as deleting your account.

Check that you have an internet connection and that you are signed in.

Then try closing and reopening the app, or signing out and back in. If logs still do not appear on another device, make sure you are using the same account on both devices.

If the problem continues, email support@onscale.app with a short description of what you expected to see and which device you are using. Please do not send passwords.

OnScale Premium unlocks additional tracking tools, including meal and drink photo scan, barcode scan, history, past weigh-in goals, and extended trends.

Subscriptions are monthly or annual and are billed through the Apple App Store. We do not collect your payment details in the app.

To subscribe, open Profile and choose Subscribe, then complete the purchase in the App Store sheet.

To manage or cancel, go to iPhone Settings → your name → Subscriptions, and select OnScale. Apple handles billing, renewals, and cancellations.

Promo codes provide complimentary Premium access. Redeem a code in Profile → Redeem Code.

Redeeming a code requires a signed-in cloud account. Codes may have expiration dates or other limits shown at redeem time.

Free includes manual food and drink logging, today’s nutrition, and basic tracking.

Premium includes meal and drink photo scan, barcode scan, history, past weigh-in goals, and extended trends.

Feature availability can vary slightly by app version. If something looks locked, check Profile for Subscribe or Redeem Code.

Take a photo of your meal. OnScale uses automated analysis to estimate nutrition, then you review and edit the result before saving it to your log.

Scans are estimates only — they are not lab measurements or medical assessments. Always check the values before you log them.

Barcode scan looks up packaged foods in public nutrition databases, including USDA FoodData Central and Open Food Facts, then lets you review and log the item.

Database matches can be incomplete or out of date. Confirm serving size and macros before saving.

No. OnScale provides educational tracking tools only. It is not medical, dietary, or sports-medicine advice, and it is not a substitute for a coach, registered dietitian, physician, or other qualified professional.

If you are cutting weight, returning from injury, or managing a health condition, talk with your coach and clinician before changing how you eat, hydrate, or train.

Yes. You can log food and drinks manually and search nutrition databases without using the camera.

Photo scan and barcode scan are optional Premium tools. Manual logging is enough for day-to-day tracking.

No. We do not sell your personal information, and we do not use your health logs for third-party advertising.

Photos you take for meal, drink, or barcode scans are processed to produce nutrition estimates. When you use scan features, image content may be sent to our AI provider so the estimate can be generated.

You choose the photo at scan time using the system camera or photo picker. Manual logging does not send photos for AI analysis. See the Privacy Policy for details.

Your logs are tied to your account. Other OnScale users cannot browse your weight, food, hydration, or workout history.

We may access account information only as needed to operate the service, fix issues you report, or meet legal obligations. Details are in the Privacy Policy.

Email support@onscale.app. Include your account email (if you have one), device model, iOS version, and a short description of the issue.

Do not send passwords, verification codes, or screenshots that include secret keys.

We aim to respond within 1–2 business days. Response times can be longer around launches, holidays, or periods of high volume.
