Track your shots.
Hit your protein.
Penvia helps you remember your weekly shot, rotate injection sites and eat enough protein when your appetite is low. No account. Your data stays yours.
Everything for shot day, in one calm app
Built for people who take a weekly injection and want a simple, private way to stay on track.
Log a shot in 3 taps
Pick the dose, tap the spot on the body map, save. See a countdown to your next shot and get a reminder on shot day.
Rotate your sites
Penvia suggests the area you used least recently, so you can spread injections around.
Hit your protein goal
A protein ring, plus fiber and water. Scan a barcode or label, or type what you ate. Every food gets an A to E grade.
Share a clear report
Make a PDF of your shots, weight and side effects to show your doctor, or export everything as CSV for free.
See how it looks
Real screens from the app.
Private by design
We do not want your health data, so we built Penvia not to collect it.
No account
Open the app and start. No sign-up, no email.
No analytics or ads
No tracking and no third-party analytics in the app.
Stays on your iPhone
Your entries are saved on your iPhone only. We have no server, so we cannot see them.
Get told when it is ready
Send us one email and we will write back once, on launch day. We use your address only for that and never share it.
