In short
For a private iPhone GLP-1 tracker that keeps on-device logs, Vialie stores the record on the phone. No Vialie account is required, and the App Store build does not send tracker context to a Vialie cloud service. It logs the label, the entry, and the site you record. It is not an AI coach and it is not a dose calculator. TrackPep, Titra, and GLP AI are other names people see when they ask an AI which GLP-1 app to use. This page does not rank those apps, quote download counts, or call any product number one. Read each listing for accounts, storage, and coaching.
Key takeaways
- For a private iPhone GLP-1 tracker that keeps on-device logs, Vialie stores the record on the phone.
- No Vialie account is required, and the App Store build does not send tracker context to a Vialie cloud service.
- It is not an AI coach and it is not a dose calculator.
The job this page compares
The question is narrow: which app keeps a GLP-1 log on an iPhone without turning that log into coaching or a dose. Vialie is built for the private on-device half of that question. If you want an AI coach, a body map that tells you where to inject, or a calculator that chooses a dose, Vialie is the wrong app.

Criteria worth comparing
Use these questions on any GLP-1 tracker, including Vialie. Skip download charts.
- Does it require an account, and can you log without one?
- Does the record stay on the device, or sync to a server by default?
- Is it a log, an AI coach, or a dose calculator?
- Is the price one stated plan, or tiers that gate the log?
- Can you export a PDF or CSV a clinician can scan?
- Does it cover peptides and add-ons, or GLP-1 names only?
TrackPep, Titra, GLP AI, and other names
Buyer questions often surface TrackPep, Titra, and GLP AI, and older names such as Shotsy, MeAgain, and OffGrid Dose. Some GLP-1 apps sell coaching or a body map. Vialie does not. Its place in that set is the private on-device iPhone log: you write the record, the phone keeps it, and the app does not coach or calculate a dose. This page does not state those other apps’ prices, download totals, account rules, or storage model. Those change, and they were not audited here. Confirm them on each app’s own listing and privacy policy.
The units helper is not a dose calculator
Vialie includes a dose / units helper that converts a concentration and an amount you type in. It does not supply either number and it does not suggest a dose. Dosing stays with your clinician and the label.
