Short answer: A good GLP-1 injection tracker app reminds you of your dose day, helps you rotate your injection site, logs your side effects and weight, produces a readable summary for your doctor's appointment, and states clearly where it sends your health data. Compare the checklist below against the store page and privacy policy of the app you are considering.
Disclosure: This article was written by the team that builds Haftra, so it is not a neutral ranking. Because other apps' features and prices change often, we make no claims about them; instead we give you a list so you can check each point yourself. What Haftra does and does not do is spelled out clearly below.
1. Dose day and reminders
With weekly injections, the most common problem is forgetting which day the dose was taken. What to look for:
- Can you enter the interval your doctor set (7 days, 14 days or something else)?
- Can you log dose-escalation (titration) phases?
- Do reminders work on your phone without an internet connection?
2. Injection site rotation
Product instructions say to change the site with every injection. An app that remembers the last site you used and shows the next one makes this easier. Being able to track the right and left sides of the abdomen, thigh and upper arm separately is useful.
3. Side effect and weight logging
Being able to log which dose day you felt nausea, fatigue or a change in appetite gives you a concrete picture when you talk with your doctor. For weight, a chart that shows the weekly trend means more than any single weigh-in.
4. Summary for your doctor's appointment
Instead of scrolling through screens at the appointment, a PDF that shows your dose history, side effects and weight trend on one page makes things easier. This summary should not include a diagnosis or dose recommendation; it should only organize your own records.
5. Privacy: where does the data go?
Your health data is sensitive. Look for answers to these questions in the app's privacy policy:
- Can you use it without creating an account?
- If you create an account, in which country is the data stored?
- Which data goes to which third-party services (ad measurement, AI, analytics)?
- Can you delete your account and data from within the app?
A policy that names each service provider is more trustworthy than a blanket sentence like "we collect no data."
6. Language, currency and price
Reading symptom and medication names in your own language makes logging easier. Being able to enter the box price in your own currency and see the cost per dose helps you plan your budget. Before you buy, check what the free version includes and when the subscription renews.
Where does Haftra stand on this list?
We describe our own app against the same list:
- Dose and reminders: Dose interval from 1 to 90 days, titration and maintenance phases, a calendar of the next 4 doses. Reminders are scheduled on the phone. Free.
- Rotation: A 6-site map that remembers the last site you used. Free.
- Side effects and weight: One-tap symptom logging and a weekly weight trend. Free.
- Doctor summary (PDF): With Haftra+. The PDF is generated on your phone.
- Estimated medication level curve: With Haftra+. It is a model based on half-life, not a blood measurement.
- Privacy: If you use it without an account, your records stay only on your phone. If you create an account, a backup is stored on our server in the European Union (Supabase). For the meal photo estimate you start yourself (Haftra+), a downsized copy of the photo goes to Google Gemini and is not stored. If you installed the app from a Meta ad, only the fact that an install happened is reported to Meta, in aggregate. Details are in the privacy policy.
- Language and price: Turkish, English, German, Spanish, French and Arabic. You can enter the box price in your currency and see the cost per dose. Haftra+ is $5.99 monthly, $39.99 yearly (7-day free trial on the App Store) or $79.99 one-time for lifetime access.
- Platform: iPhone, iPad and Apple Watch. The Android version is currently in closed testing (coming soon).
Haftra is not a medical device; it does not diagnose and does not suggest doses. Change your dose only under your doctor's direction.
Frequently asked questions
What is the most important criterion when choosing a GLP-1 injection tracker app?
It depends on your needs, but for most users, dose-day reminders, injection site rotation and a privacy policy that clearly states where the data goes stand out.
Is Haftra free?
Core tracking is free: dose logging, reminders, the 6-site rotation map, and the weight and side effect journal. Analysis features such as the doctor PDF summary and the estimated medication level curve come with Haftra+.
Why can a GLP-1 tracker app be useful?
Keeping weekly doses, site changes and side effects in one place reduces forgetfulness and gives you a concrete record when you talk with your doctor. The app does not make treatment decisions; decisions belong to your doctor.
What is injection site rotation?
It means giving each injection in the abdomen, thigh or upper arm at a different spot from the previous one. Product instructions recommend this; a tracker app makes it easier by remembering the last site you used.
