Why Protein First?

When appetite drops, protein becomes essential.

GLP-1 medications (like semaglutide and tirzepatide) significantly reduce hunger signals. Without a clear daily target, it's easy to under-fuel and lose lean muscle mass alongside fat.

Frequently Asked Questions

Clear answers about Dose & Fuel.

Everything you need to know about tracking, privacy, and protein goals.

What medications does Dose & Fuel support? ▼

Dose & Fuel lets you log user-entered records for any prescribed GLP-1 medication, including semaglutide (Ozempic®, Wegovy®), tirzepatide (Mounjaro®, Zepbound®), liraglutide (Saxenda®, Victoza®), and daily oral options. You can record your prescribed dose schedule, dates, and reminders.

Why is protein tracking so important while using GLP-1 medications? ▼

GLP-1 medications reduce appetite significantly. When eating less, adequate daily protein intake is vital to help preserve lean muscle mass and maintain energy. Dose & Fuel prioritizes daily protein goals without requiring you to obsess over aggressive calorie restriction.

Does Dose & Fuel give medical or dosing advice? ▼

No. Dose & Fuel is strictly a wellness tracker for your personal records and daily habits. It never prescribes, recommends, or modifies doses, titrations, or medical treatments. Always consult your doctor or prescribing clinician for medical guidance.

How does the AI photo meal scanner work? ▼

You simply take a photo of your meal and our advanced vision AI analyzes the ingredients and calculates your protein intake in 1 second. You can review, adjust portions with smart presets, and confirm every item before it is saved to your daily log.

Is my medical and weight data kept private? ▼

Yes. All your medication logs, weight entries, and notes are encrypted and stored locally on your iPhone using SQLite. We do not sell data to advertisers, and we never sync medical history with third-party brokers.

Can I export my tracking history to share with my clinician? ▼

Yes. You can export your complete factual history as versioned JSON at any time with one tap, or review your historical logs directly on your iPhone during your clinician appointments.
