App asks to subscribe again
Step 1 — Check your subscription
Many scanner features require Welmi Pro. The free plan allows only 1 meal per day.
If the camera or photo upload stopped working after you logged your first meal of the day, for example you cannot add a second photo, you have most likely reached this daily limit on the free plan. Pro removes it.
iPhone: Settings → Apple ID → Subscriptions → Welmi
Android: Google Play → Subscriptions → Welmi
If your subscription is active but the app does not recognize it, skip to Step 5.
Step 2 — Check your internet connection
AI-powered scanning requires a connection to our servers. Try the following:
Switch between Wi-Fi and mobile data.
Disable any VPN or ad-blocker apps (except in the case below).
Try again with a stable connection.
Photos or scans fail in Spain during football matches. Unlike the general advice above, a VPN can help in this case. While football matches are broadcast, internet providers in Spain sometimes temporarily block large groups of internet addresses to stop illegal streams, and Welmi can get caught in these blocks. This is not a problem with your account or the app. Access usually comes back by itself after the match ends. Until then, switch to mobile data or another provider, or turn on a VPN.
Step 3 — Restart the app
Close the app fully (swipe it away from the app switcher) and reopen it. If the problem persists, wait 30-60 minutes — the issue may be a temporary server disruption on our side.
Step 4 — Update the app
Make sure you are running the latest version of Welmi. Open the App Store (iPhone) or Google Play (Android) and install any available updates.
Step 5 — Restore your purchase
If you have an active subscription but the app does not recognize it:
Open the app.
Go through the onboarding/paywall screen.
Tap the Restore button on the pricing screen.
Do not start a new trial or purchase a new subscription.
For detailed instructions see Restore your purchase.
Step 6 — Contact support
If none of the steps above resolved your issue, please contact us and include:
A screenshot of the error message
Your subscription status (active/expired/none)
Device type and OS version
App version (found in app settings)
Tips for better food recognition
Use good, even lighting — avoid dark or backlit environments.
Center the food in the frame.
Remove clutter and other items from the background.
For barcodes, hold the phone straight-on and close to the label.
Calories or macros look wrong
A photo scan gives an estimate. The AI identifies the dish and guesses the portion size, so mistakes happen, especially with homemade dishes. Find your case below.
A product or dish shows the wrong calories or macros.
Open the meal card.
Check the weight. If it is wrong, tap the weight with the pencil icon, enter the correct amount and confirm it. Welmi recalculates the calories and macros in the card and in your day total.
If the weight is right but the values are not, tap the calories, protein, carbs or fat value and enter the correct number.
If the AI picked the wrong product altogether, for example a coffee drink with milk and sugar instead of black coffee, delete the entry and add the food again through Search. Tap the red "+" in the bottom-right corner (on the new home screen without it, tap a meal circle under Meals Logged), choose the matching item and enter the exact weight. Search is the most reliable way to log food, because you choose the item and the weight yourself.
In Search, pick the item that matches what you weighed, raw or cooked.
Once the values are right, save the food to Favorites. Next time you can add it in one tap with the red "+" → Favorites (on the new home screen: a meal circle → Recent Meals → Favorites), and you will not need to fix it again.
The day total is higher than the meal I see on the home screen.
The meal slot on the home screen shows only the last dish you added, but the day total counts every entry in that meal. To see everything you logged, open the Nutrition tab and tap Journal > just below the profile icon (on the new home screen: View all > next to Meals Logged). From that list you can open, edit or delete each entry.
Photo and voice logging give different numbers for the same meal.
The two methods estimate in different ways. With a photo, the AI recognizes the dish by how it looks and estimates the portion size itself. With voice, it uses your description and takes a standard portion unless you say the weight. Voice input is usually more accurate when you name the weight, because it removes the error of estimating the portion from a photo. For the most precise result, use Search and enter the exact weight.
I renamed a dish, but the calories did not change.
This is expected. The name is only a label for the entry. Calories and macros come from the dish's ingredients and weight. To change the values, open the meal card and change the weight or the ingredients, and Welmi recalculates the numbers. If the AI recognized the wrong dish, delete the entry and add the right one through Search.
My daily calorie goal on the home screen is higher than the one I set.
The Add Burned Calories option is probably on. It adds the calories you burn during the day to your goal, so the number grows with your activity. You can turn it off in Profile → Calories & Macros. See Set up your goals.
Frequently asked questions
Wrong calories displayed. AI recognition is an estimation. If the values seem off, tap the entry and edit the calories or portion size manually.
Can I add food without using the camera? Yes. Use the search bar, voice input, or pick from your favorites — all available from the logging screen.
Is there a daily scan limit? Free plan: 1 meal per day. Pro plan: unlimited meals, with approximately 25 AI-powered recognitions per day (server-side limit).
I bought the AI Bundle but still cannot scan. The AI Bundle is a separate product and does not include Welmi Pro features. A Pro subscription is required for unlimited scanning.
My entries disappear after I save them. This is usually caused by an unstable internet connection. Make sure you have a reliable connection when logging food, and update to the latest version of Welmi.
Does family sharing work with Welmi Pro? No. Each family member needs their own subscription.
How do I log tea or coffee? Add them as food items in any meal slot (breakfast, lunch, dinner, or snacks).
The nutritional data for a product is wrong. You can edit values manually after logging. If the product data is incorrect in our database, please report it to [email protected] so we can update it.
The weight shown for my food is wrong. AI estimates portion weight automatically. You can adjust the weight manually after scanning.
Important notes
AI recognition is less accurate for regional dishes and homemade meals. Always verify values before saving.
Our global product database is continuously improving — update the app regularly to benefit from the latest data.
The "burned calories" setting in your profile affects your daily calorie targets. Make sure it is configured correctly.
