About this app

Vialume is a private GLP-1 shot & weight loss tracker — no account, no cloud, your data stays on your phone.

I built Vialume because I'm on this journey myself.

When I started on a GLP-1, I wanted one app that kept the whole picture — my shots, my weight, what I manage to eat when my appetite disappears, how side effects track against dose changes — without locking my own charts behind a subscription or shipping my health data to someone's cloud. I couldn't find it, so I built it. Vialume is the tracker I use, priced to be within everyone's reach.

YOUR WHOLE JOURNEY, ONE PLACE
• Shot tracker with dose, injection-site body map and rotation hints
• Weight loss tracking with 7-day rolling average, BMI and total lost
• Already started somewhere else? Backdate everything. Set your Journey Start and Starting Weight and your history counts from day one
• Protein and water targets with quick-log — protein is the metric this journey under-hits
• Side-effect log charted against your dose changes
• Charts for all of it: weight trend, dose over time, protein & water, side effects vs dose
• Home-screen widget: next-shot countdown and last weight
• Health Connect sync for weight (beta)
• Full backup export and CSV import — your data is portable, always

A SHOT TRACKER THAT FITS REAL SCHEDULES
Weekly, twice-weekly, or split dose days — Mon and Fri, at your own times. Log a shot in seconds, tap the injection site on the body map, and let the rotation hint pick the next one. Logged it late, or forgot until Tuesday? Every record is backdatable and editable, so your history stays honest.

PRIVATE BY DESIGN
No account. No cloud. No analytics. No ads. Everything you log lives in a database on your phone and nowhere else. We couldn't see your data if we wanted to — it never leaves your device unless you export it yourself. Optional biometric app lock keeps it from curious hands too. If you have been looking for an offline, private health tracker with no sign-up, this is it.

FAIR PRICING, HONEST MOTIVES
Every feature above is free. Not "free trial" free — free. Your data is yours, and looking at your own charts will never cost you anything — including the medication-level curve other apps charge for.

Vialume Plus (A$8.99/month or A$39.99/year) adds the extras: smart Shot Day and weekly injection reminders, pen warm-up and weigh-in alerts (reschedule-proof, with discreet-text option), doctor-ready PDF reports, progress-photo compare with stats overlay, and tracking two medications at once. Extras we compute for you — never access to what you already told the app. The cheapest annual price of any GLP-1 tracker we could find, and the only one that handles multiple medications. No free-trial tricks, no paywall sprung after you've entered your data, and anything that ships free stays free. This is a tool built by one person on the journey, for everyone else on it.

MADE FOR
People prescribed GLP-1 or GIP/GLP-1 medications such as semaglutide or tirzepatide (Ozempic®, Wegovy®, Mounjaro®, Zepbound®) who want to track their treatment journey. Vialume is not affiliated with, endorsed by, or connected to Novo Nordisk, Eli Lilly, or any pharmaceutical company. All trademarks belong to their respective owners.

IMPORTANT
Vialume is a tracking tool, not a medical device. It does not provide medical advice, never recommends doses, and never changes your schedule for you. Always follow your prescriber's instructions and consult a qualified medical professional about your medication and health.
