Common Questions

Everything you need to know

Is my health data private and safe?

Completely. Reta stores all data on your device and your private iCloud account. There are no external servers, no accounts to create, and no data collection on our end. We never see your weight, medication, or health data — nobody does but you. You can also lock the app with Face ID or Touch ID for an extra layer of privacy.

What GLP-1 medications does Reta support?

All of them. Reta supports retatrutide, tirzepatide (Mounjaro, Zepbound), semaglutide (Ozempic, Wegovy), liraglutide (Saxenda), and more. It works equally well with brand-name prescriptions and compounded formulations. You can also track multiple medications at once if you switch or stack.

Does Reta give medical advice?

No — and that's intentional. Reta helps you track and understand your own data. It shows patterns and trends, but it never tells you what to do medically. Always follow your healthcare provider's instructions. Think of Reta as a really organized journal, not a doctor.

Is Reta free to use?

Yes. Injection tracking, nutrition logging, weight and progress tracking, side effect monitoring, and smart reminders are all free. No account required, no trial period, no feature gates. Premium features with advanced insights will be available in the future for those who want them.

Does it sync across my devices?

Yes. Reta uses your private iCloud to sync across all your Apple devices automatically. Log a shot on your iPhone, see it on your iPad. No extra setup needed — if you're signed into iCloud, it just works. Your data stays encrypted and never touches our servers.

What exactly can I track?

Everything that matters on your GLP-1 journey: injection doses and sites, estimated medication levels, side effects and their severity, weight and body measurements, BMI, protein, water, fiber, calories, steps, workouts, and progress photos. Reta connects all of it so you can finally see how your medication, nutrition, and symptoms relate.

How is Reta different from Shotsy or MyFitnessPal?

Most apps solve one piece — Shotsy tracks injections, MyFitnessPal tracks food, Apple Health tracks weight. Reta is the only app that connects medication, nutrition, symptoms, and progress into one picture. It's also fully private (on-device data, no accounts), has a generous free tier, and is built specifically for the GLP-1 experience — not adapted from a generic calorie counter.

Will it work with my specific dose or compounded medication?

Absolutely. You can set any medication name, dosage, and injection schedule — including custom compounded formulations at any concentration. Whether you're on 2.5 mg semaglutide, 5 mg tirzepatide, or a compounded retatrutide blend, Reta adapts to your protocol. Not the other way around.

Reta helps you track your GLP-1 medication and wellness journey. It does not provide medical advice, diagnosis, or treatment. Always follow your healthcare provider's instructions regarding your medication.
