I built an app to track Mounjaro injections, weight & side effects โ looking for honest feedback
Hey everyone ๐
I started Mounjaro a while back and got frustrated using spreadsheets and random notes to track my injections, weight, and how I was feeling each week. So I built an app for it.
It's called My Shot GLP-1 Diary (or La Mia Penna on the Italian store โ I'm Italian ๐ฎ๐น). It's on both iOS (currently in review) and Android (live now).
Here's what you can do on the **free plan** :
- ๐ **Injection tracker** with a visual body map for rotation sites + automatic countdown to your next dose (up to 4 logs to try it out)
- โ๏ธ **Weight tracking** with trend charts, total lost since day one, and goal projections (up to 20 logs)
- ๐ธ **Progress photo gallery** stored securely and separate from your camera roll (up to 2 uploads)
- ๐ฝ๏ธ **Food diary** with barcode scanner and one free AI food scan per day โ just take a photo of your meal and it estimates calories and macros
- ๐ฃ **Side effects log** to track how you feel after each dose (up to 10 logs)
- ๐ **Body measurements** to track waist, hips, etc. (up to 10 logs)
- ๐ค **AI Health Coach** โ describe how you're feeling and get personalized insights (5 free per month)
Basically you get a real taste of every feature before deciding if Pro is worth it.
**Pro unlocks:**
- ๐ Unlimited injections, weight, measurements, side effects, and photos
- ๐งฌ **Pharmacokinetics chart** โ a unique feature that shows the estimated level of active drug currently in your system, calculated using the exact half-life of your medication
- ๐ฉธ **Glucose tracking** for those monitoring blood sugar
- ๐ค AI Coach daily instead of monthly + weekly PDF reports you can share with your doctor
- ๐ฝ๏ธ 5 AI food scans per day instead of 1
I'd love brutally honest feedback โ what's useful, what's missing, what would make you actually use this daily. I
