dev@adelyons.comHow do I set my daily goal?
Open Settings → Daily protein. Enter grams directly, or switch to g/kg and enter your body weight to work it out from a preset range — a muscle-protection range for people on GLP-1 medications, or a higher range for active training. These are planning figures to start from, not medical advice.
What are the fastest ways to log?
In order of speed: tap a favorite to re-log something you eat often; Add to type grams or pick from the built-in common-foods list; Scan for a packaged item's barcode; Photo for an AI estimate of a plate. Toggle "save as a favorite" while adding and it is one tap next time.
How accurate are the photo estimates?
They are estimates, and they say so — you get a likely figure with a low and high range, and you confirm or adjust it before it saves. Portion size and anything hidden in the frame are what the model cannot see, so photograph the plate from above with everything visible, and nudge the slider when you know better.
A barcode didn't scan or the product was missing.
Barcode data comes from Open Food Facts, a community database, so some products are missing or incomplete. When that happens, use Add and type the grams from the packaging — it takes a few seconds and you can save it as a favorite.
How do I turn on the fiber track?
Settings → Fiber track. It adds a second thin ring and a fiber field to every logging path. It is off by default and stays off unless you want it.
What's free and what's Pro?
Free covers unlimited manual, favorite, and barcode logging, the dial, streaks, seven days of history, and five AI photo estimates to try. Pro adds unlimited photo estimates, full history and the calendar heat view, home-screen widgets, the fiber track, and reminder customization.
What are the plans?
Annual starts with a 7-day free trial and then bills yearly. Monthly bills monthly. Lifetime is a single one-time purchase. Because each photo estimate has a real processing cost, unlimited estimates on all plans are subject to fair use. Prices come from the App Store or Google Play and are shown in the app before you buy.
How do I restore my purchase?
Go to Settings → Restore purchases, or the Restore link on the upgrade screen. Make sure you're signed in to the same App Store or Google account you purchased with.
How do I cancel my subscription?
Manage or cancel anytime in your device's store settings: App Store → your name → Subscriptions, or Google Play → Payments & subscriptions. A one-time Lifetime purchase has nothing to cancel.
Where is my data stored?
On your device. There is no account and no cloud sync. Two features use the network when you use them: a photo estimate sends that photo to Google's Gemini model for processing, and a barcode scan sends only the barcode number to Open Food Facts. Full detail is in our Privacy Policy.
Does it sync with Apple Health or Google Fit?
Not in this version. Protein Only does not read or write health data on your device.
Is this medical advice?
No. Protein Only is a tracking tool, and its goal presets are general planning ranges rather than a prescription. If you take a GLP-1 or other medication, are pregnant, or have a health condition, ask your doctor or a registered dietitian what target is right for you.
