My GLP Shot vs MeAgain
Both apps are aimed at people on GLP-1 medications like Mounjaro, Ozempic, Wegovy, and Zepbound. The difference is what you actually pay, how much of the app sits behind a paywall, what the company does with your data, and whether the product tries to also sell you medication.

Quick verdict
- If you want a free tracker without an upfront paywall: My GLP Shot. The free tier is fully usable on its own — no nag screens, no time-limited trial, no card on file.
- If you want medication tracking bundled with telehealth and a pharmacy: MeAgain. Their Care tier ($30/month on top of the app) wraps in clinical services and prescription fulfillment. We don't do that — by design.
- If you want the lowest annual cost for premium tracking features: My GLP Shot at $19.99/year flat. MeAgain Premium runs about $120 per year for the app alone.
- If privacy is the priority: My GLP Shot. Local-first by default, end-to-end encrypted optional sync, open-source code on GitHub.

The paywall question
The biggest practical difference: MeAgain's tracking sits behind a subscription. There is no documented free tier; users coming in from search or App Store browse hit a paid onboarding flow. That is a legitimate model — many apps work that way — but it is the opposite of what we do.
My GLP Shot's free tier is the product. Shot logging, weight tracking, mood and appetite, the active-medication concentration chart, the mixing calculator, custom dosing schedules, reminders, and the full 32-milestone achievement system are all free. No card on file, no expiring trial, no feature gating that surfaces three taps in. The optional $19.99/year premium adds advanced features (lab tracking, body measurements, supply inventory, doctor-share PDF) for the subset of users who want them.
The telehealth bundle
MeAgain's "Care" tier wraps prescription fulfillment around the tracker for around $30 per month, with reported medication costs of $149-$299 per month if you fill through them. That has real upside if you want the convenience of one bill and one app for clinical access plus tracking.
It also creates a structural issue. When the same company sells you the tracker, the medical visit, and the medication, the product has a financial incentive to keep you taking medication. We chose not to be that company. My GLP Shot is a tracker. The prescriber is your prescriber. The pharmacy is your pharmacy. The data is yours.
The privacy story
My GLP Shot defaults to local-only storage. Shots, doses, weights, mood, body measurements, lab values, photos, and notes never leave your device unless you explicitly opt into cloud sync. If you do turn on cloud sync, the encryption happens in your browser before any byte hits the server:
- Your password is run through PBKDF2-SHA-256 with 600,000 iterations in the browser to derive both an authentication token (sent to the server) and an AES-256-GCM key (kept on your device).
- All synced data is encrypted with that AES-256-GCM key using a fresh random 12-byte IV before upload.
- The server stores opaque ciphertext only. We have no key material. We cannot read your data even if compelled to.
- Doctor-share links generate a fresh per-share AES key and place it in the URL fragment after the
#. URL fragments are not sent to servers, so the share link's key never reaches us either.

The pricing math
Over five years, MeAgain Premium at $10/month is $600 for app access. My GLP Shot premium for the same five years is $99.95. If you also use MeAgain Care, add another $1,800 over five years on top of the medication itself.
For most users tracking a multi-year medication routine, the math favors a tracker that bills like a tracker, not like a clinic.
When MeAgain is the better choice
- You want telehealth, prescriber access, and prescription fulfillment all in one app and one bill.
- You strongly prefer a native app over a Progressive Web App.
- You don't need lab tracking, mixing calculations for compounded peptides, or a doctor-share PDF, and the monthly subscription cost isn't a concern.
When My GLP Shot is the better choice
- You already have a prescriber and just need a tracker.
- You want a real free tier — not a trial.
- You want your medication data on your device, not on a vendor's server.
- You want to verify what an app actually does by reading the source.
- You're on a compounded peptide and need a mixing calculator that handles vial mg + BAC water + custom syringes.
- You want lab tracking, body measurements, or PDF doctor-exports for appointments.
- You want a single web-based PWA that works on any device with a browser.
