Vialog on Android — the dose log for people who mix their own vials
What it does

Keep the log. Skip the arithmetic.

💉

Log a dose in seconds

Amount, time, route and injection site, plus a rating and notes you'll actually want later. Full history grouped by day.

🧪

Vial tracking

Watch a vial draw down as you log — remaining volume, estimated doses left, and a reminder before its discard date.

🧮

Reconstitution & syringe units

Enter strength and diluent volume; Vialog works out concentration and converts every dose into insulin-syringe units.

📅

Schedules & reminders

Turn your routine into a daily checklist — daily, chosen weekdays, every N days, or on/off week cycles — with optional reminders.

📈

See what's happening

Weight, body fat, waist and glucose alongside your log. Side effects with severity, adherence, streaks and per-item history.

🔒

Built to be private

Visible only to you. No advertising, no analytics SDKs, no third-party trackers. Export any time; delete everything from inside the app.

Now on Google Play.

Get the Android app from Google Play, or use it on the web from any phone.
