Full breakdown below, before you sign up for anything.
The calculator
Enter the vial, the water, and your dose, and Vialog shows exactly where to draw on an insulin syringe, with a diagram. No more redoing the math on your phone calculator with a needle in your other hand.
The log
Log a dose in seconds, add a rating and a note, and your full history is always there. Weeks from now you'll know exactly what you took and when, instead of scrolling a notes app hoping past-you wrote it down.
The inventory
Track sealed vials with acquired date, source, and cost, plus whatever's currently mixed. Free keeps 2 on hand; Pro tracks your whole stock and warns before anything expensive dies quietly in the back of the fridge.
Estimated levels · Pro
For compounds with a known half-life, Pro charts an estimated-levels curve with a forward projection as you keep logging. It's a model, not a measurement, and the chart says so. We'd rather be straight with you than impressive.
Privacy
No ads, no analytics SDKs, no trackers, and no investor asking what your data is worth. Export everything any time, or delete it permanently in-app, and it's actually gone.
The price list
You know the app that walks you through onboarding and then springs the paywall? This is the opposite. Here's everything, up front.
Logging is free forever. That's a promise, not a trial. Pro exists for people running more than the basics, and $99 means never thinking about it again.
Who makes this
Vialog is self-funded and built by one person who got tired of spreadsheets and syringe math. No ad deals, no data buyers, no growth team. If it's useful, tell a friend. If something's broken, tell me and I'll fix it.
Questions
Yes. There are no ads, no analytics SDKs, and no trackers in Vialog. Your log stays your log. You can export it any time or permanently delete it in-app, and deleted means deleted.
Logging is free forever: unlimited doses, full history, the reconstitution calculator, 2 vials on hand (sealed or mixed), 1 protocol with reminders, weight and side-effect logging, and export. Pro ($39.99/year or $99 lifetime) removes the vial limit and adds low-vial and discard warnings, the estimated-levels curve, unlimited protocols with on/off cycling, household sharing, and correlation views.
No. Vialog does not recommend compounds, dosages, or protocols, and it never will. You decide what you do with a healthcare professional. Vialog keeps the record.
The Google Play app is launching shortly. Today, Vialog installs as a web app from vialog.getforgeworks.com and works on any phone, Android or iPhone. Same app, same data.
Yes, any time, on the free tier included. It's your data. No lock-in, no "upgrade to export."
No. Log your doses, track your weight and side effects, set a reminder, done. And if you ever start mixing your own vials, everything's already in one place.
