Your journey. On your phone.

Made for your everyday

One place for the journey you actually track

Log the facts, see the trend and keep the record yours.

Shot log + body map

Actual Dose, injection site with rotation hints, pain and notes. The map remembers where you've been.

Reminders that keep up Plus

Shot Day, pen warm-up and weigh-in — each on its own schedule, with weigh-ins daily or on the days you pick. Change a Shot Day, split your dose or backdate an entry and they all recompute themselves. Discreet mode keeps your Medication off your lock screen. Reminders are part of Vialume Plus, the paid subscription.

Multiple Medications

Each Active Medication keeps its own Dosing Schedule and reminders. Charts focus on the first Medication by default and remember the series you choose.

Started before the app?

Backdate everything. Set your Journey Start and Starting Weight — your history counts from day one.

Charts, all free

Weight trend with a 7-day average, Actual Dose, side effects, protein and water — plus an illustrative medication-level curve. The curve is an estimate from published half-lives, never a measurement.

Tap any chart, full screen

Every chart opens landscape at full width, so a year of data reads as a year — not a thumbnail. Switch between 1, 3, 6 and 12 months without leaving it, and tune dose labels and chart style to taste.

kg, lb, or st & lb

Show and enter weight in kilograms, pounds, or stones & pounds. Your records are stored exactly as you logged them — switching units never rewrites a single entry.

Protein-first nutrition

When appetite disappears, protein is the metric that slips. Targets and quick-log for protein and water.

Side effects vs dose

Log nausea, fatigue and more with severity — charted against your dose changes so patterns show.

Progress Photos

Build a private, backdatable visual timeline on your device. Vialume Plus adds first-and-latest comparison and an optional stats overlay.

Peptide & vial tools

Enter the values from your vial, syringe and pharmacy instructions to calculate volume, view a U-100 barrel-marking schematic and estimate one vial's supply. Vialume never recommends what to inject.

Widget + Health Connect Beta

Next-shot countdown on your home screen. Weight syncs with Health Connect; steps read in.

Health Connect sync is still in beta testing — it may not work reliably on every device yet.

Yours to keep

CSV and JSON export any time, single-file backup and restore, biometric app lock. Plus adds a silent daily backup into a folder you choose — on your device or SD card, never a cloud you didn't pick.

No Vialume account. No Vialume cloud. Yours.

Everything you log lives in app-private storage on your phone. Vialume itself does not transmit health records: there is no sign-up, cloud sync, analytics, advertising or crash-reporting SDK. Your operating system's backup service may copy app-private data according to your device settings.

  • Local SQLite storage — uninstall deletes it, backup keeps it
  • Optional biometric lock
  • Discreet reminder text — your medication is your business
  • Read the full privacy policy

Built by a software developer on the 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. I wanted something more accessible and more customisable than what was out there: backdate anything, tune your reminders, keep it discreet, take your data with you. Vialume is the tracker I use every week, priced to be within everyone's reach.

I believe in privacy and data transparency, and have opted for the data to be stored on your phone — controlled by you.

I spent a lot of time and thought developing this, and I understand the user base — so I made sure every critical element stays free to use. I only ask that you consider subscribing if you think it's worth it. I appreciate you all for downloading. Please feel free to reach out if you have any suggestions.
