Help with Fuelprint, the AI food diary and supplement tracker for iPhone and iPad.

Common questions

How do I type or paste a whole day?

On Today, tap Type or paste a list. Write one thing per line, such as "2 eggs and toast", "5g creatine" or "30 min walk". Fuelprint sorts each line into food, drink, supplement, activity, feeling or other; tap a line's icon to change it. To log several days at once, put a date line such as 10/06/26 or Oct 6 before each day. Pasting the same list again only adds lines you haven't logged yet.

How does Ask AI work?

Open Ask AI from its tab or the orange card on Today. Pick a period and one of 15 questions, then tap Send to AI and choose ChatGPT, Claude, Gemini, Perplexity, Copilot or Grok. Fuelprint copies the prompt and opens the assistant; if it opens empty, tap the message box and paste. Fuelprint builds the prompt on your phone and never sends it anywhere itself.

What should I put in My Profile?

Anything that helps the AI give answers that fit you: age, sex, height, weight, activity level, goals, diet, medical history, medications and allergies. Everything is optional and stays on your phone. Turn off "Include my profile" in Ask AI to leave it out of a prompt.

Is this medical advice?

No. AI answers can be wrong and are not medical advice, diagnosis or treatment. Talk to a doctor or pharmacist before changing your diet, supplements or medication. In an emergency, call your local emergency number.

Does Fuelprint count calories?

Not by itself, on purpose: no food database, weighing or scanning. Write meals the way you'd say them, then use the Nutrition estimate or Protein check question in Ask AI. The assistant estimates calories, protein, carbs, fat and fiber and states the portions it assumed.

How do I track supplements?

Add them to the Supplements & routines checklist on Today with a dose and an optional reminder. Tap the circle to check one off. In a pasted list, a line that names a checklist item, like "5g creatine", checks it off for that day.

How do I log with Siri?

Say "Log food in Fuelprint" and Siri asks what you had. "Log water in Fuelprint" adds a glass. "Mark Vitamin D done in Fuelprint" checks off a supplement.

How do I change the water glass size?

Tap the gear on the Today screen, then Glass size.

I forgot to log yesterday.

Use the back arrow at the top of Today to step to yesterday, or paste a list with a "Yesterday" line.

The widget isn't updating.

Open Fuelprint once; iOS occasionally pauses widget refreshes to save battery. Removing and re-adding the widget also resets it.

I'm not getting reminders.

Reminders only fire on scheduled days you haven't checked in yet. If none arrive at all, open the Settings app, then Notifications, then Fuelprint, and turn on Allow Notifications.

Does my data sync between devices?

No. Fuelprint stores everything on the device and has no servers or account. To move or keep your data, tap the gear on Today and use Export Spreadsheet or Export Complete Backup.

How do I delete my data?

Swipe left on any entry to delete it, clear any profile field, delete a checklist item to remove it and its history, or delete the app to remove everything.
