How can we help?

Don't worry, you never have to pay twice on the same platform. Sometimes the app just needs a reminder of what you already own.

iPhone & iPad: go to My profile > Premium features and tap Restore purchases. The app fetches your original purchase from the App Store and unlocks Premium again. Make sure you're signed in to the App Store with the same Apple Account you used to buy KetoDiet, and that you're connected to the Internet.

Android: Google Play normally recognises your purchase automatically. If it doesn't, go to My profile > Premium features and tap Restore purchases. Make sure your device uses the same Google account you bought KetoDiet with, and that you're connected to the Internet.

Have a KetoDiet membership from our website instead? Sign in to the app with your membership email under My profile > Account & sync, and you can always check your plan in your membership portal.

Where's My profile? On phones, go to Today > You > My profile; on iPad and tablets, tap your photo and name at the top of the menu.

Yes, with a KetoDiet membership. Family sharing is a membership feature: it isn't available for subscriptions bought through the App Store or Google Play.

As a member, open your membership portal, go to the family section and invite your family by email. Each person gets their own account and their own data, with full Premium access in the app.

Logging your food is quick:

1. On phones, open the Add tab in the middle of the tab bar, or tap Add to today on Today; on iPad, tap Add to today on Today or in Plan, or a meal's Add button on any day.
2. Adding to at the top shows the day and meal: tap it to pick another one.
3. Search for a food, pick one from Recents or the Food list, or scan a barcode.
4. Adjust the serving and tap Add.

Your day's macros update straight away, so you can see how much you have left. Short on time? Use Quick carbs under Create to log just the carbs.

Yes! You can scan packaged foods straight into your day.

• On phones, open the Add tab in the middle of the tab bar, or tap Add to today on Today; on iPad, tap Add to today on Today or in Plan, or a meal's Add button on any day.
• Tap Scan product at the top and point your camera at the barcode. The app finds the product and its nutrition for you.
• Check the serving size and tap Add.

You can also scan products when you create your own meals. Make sure the app is allowed to use the camera.

A tip: for the most accurate macros, prefer generic foods where you can. Branded products' data comes from labels and can be less complete, so the app shows a trust level for each food. See Generic foods vs barcode scanning in the app guide.

Going keto is so much easier with people around you who've been there! Join our friendly KetoDiet Support Group on Facebook: ask questions, share your progress and wins, find motivation and keep each other accountable.

Please note that we can't give personal medical or diet advice. If you have a health condition or take medication, please talk to your doctor or a registered dietitian before changing your diet. You can also find a qualified low-carb expert.

Our keto diet FAQ and the Guide in the app answer the most common diet questions too.

Data Sync keeps your days, meals, measurements and settings the same on all your devices. Syncing is a Premium feature (a subscription or a KetoDiet membership); the account itself is free.

1. On each device, go to My profile > Account & sync.
2. Tap Sign in and use the same account on every device. New to KetoDiet? Tap Create an account first.
3. That's it: your devices stay in sync whenever they're online. Tap Sync now to sync straight away.

Your devices need an Internet connection to sync: a device that's offline catches up as soon as it's back online.

Where's My profile? On phones, go to Today > You > My profile; on iPad and tablets, tap your photo and name at the top of the menu.

More in the app guide: Data sync & manage account.

First, check that you have Premium: syncing between devices is a Premium feature (a subscription or a KetoDiet membership). You can see your status under My profile > Premium features.

Then, on each device:

1. Make sure it's connected to the Internet, and go to My profile > Account & sync.
2. Check that every device is signed in with the same account (the same email), and tap Sync now.
3. Still stuck? Under Online account, tap Sign out, then Sign in again with your email and password. This gets the device a fresh connection, and syncing resumes within a few seconds. Your data stays on the device while you're signed out.

Please don't use Delete account to fix syncing: it removes your account and your data from our servers.
