The dose log for people who mix their own vials.
VialForge tracks every dose and every vial, does your reconstitution math in 3 taps, and keeps your whole history in one place. So the spreadsheet can finally retire.

Full breakdown below, before you sign up for anything.
The calculator
From powder to "draw to this line" in 3 taps
Enter the vial, the water, and your dose, and VialForge 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
Never stand there wondering "wait, did I already take that?"
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
That vial cost real money. Know where it stands.
Track sealed vials with acquired date, source, and cost, plus whatever's currently mixed. Free keeps 2 on hand and Pro tracks your whole stock. Either way, VialForge warns before anything expensive dies quietly in the back of the fridge.
Estimated levels · Pro
An honest estimate of what's still in your system
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
What you log here is nobody's business
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.

Who makes this
Built by one person who wanted it to exist
VialForge 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
Before you ask
Is my data private?
Yes. There are no ads, no analytics SDKs, and no trackers in VialForge. Your log stays your log. You can export it any time or permanently delete it in-app, and deleted means deleted.
What's free and what's paid?
Logging is free forever: unlimited doses, full history, the reconstitution calculator, 2 vials on hand (sealed or mixed) with low-vial and discard warnings, 1 protocol with reminders and on/off cycling, weight and side-effect logging, and export. Pro ($2.99/month, $24.99/year or $79 lifetime) removes the vial and protocol limits and adds the estimated-levels curve, household sharing, and correlation views. Household sharing works between Pro accounts: each member needs their own plan.
Does VialForge tell me what to take?
No. VialForge does not recommend compounds, dosages, or protocols, and it never will. You decide what you do with a healthcare professional. VialForge keeps the record.
Is there an Android app?
Yes. VialForge is on Google Play, and you sign in with the same account. It also installs as a web app from myvialforge.com and works on any phone, Android or iPhone. Same app, same data.
Is VialForge the same app as ViaLog?
ViaLog is now VialForge. We changed our name to avoid confusion with other apps using a similar name. Same app, same account, same data, just a new name and look.
Can I export my data?
Yes, any time, on the free tier included. It's your data. No lock-in, no "upgrade to export."
I only take one compound. Is this overkill?
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.
