Not just a calculator
Everything your protocol needs, in one app.
Why Dosi
Most apps track
pills. Dosi tracks
protocols.
Blood concentration curves. Pharmacokinetic modeling. A body map that remembers every site. This is what serious tracking looks like.
Smart Injection Site Rotation Tracker
Every site.
Full history.
Tap a spot on the 3D body map, enter your dose, hit log. Rotate sites intelligently. The app tracks where you've been so you never hit the same spot twice.
Reconstitution Calculator, Built In
Check label math.
Without guessing.
Enter the exact vial, diluent, concentration, and prescribed-dose values from your pharmacy or manufacturer label. Dosi checks the arithmetic without choosing missing values, preparation instructions, or a dose.
Private Protocol Education
Ask anything.
Get real answers.
Fixed definitions and Dosi's curated tracker library explain general terminology, half-life concepts, and label-based arithmetic. Customer prompts are not sent to outside AI providers. It explains; it does not prescribe.
Complete Protocol Library
If you take it,
we track it.
200+ items across 16 categories — weight management, wellness, longevity, recovery, and more. General reference data and structured tracking fields keep your records organized.
Estimated Blood Concentration Over Time
See your levels.
Not just your logs.
Every logged dose plotted against its half-life — watch each compound rise, peak, and clear, then overlay your whole stack to see how it all fits together over time.

Why not just a spreadsheet?
Because your protocol isn't a grocery list.
A notes app remembers text. A spreadsheet doesn't reconstitute anything. Dosi was built for exactly what you're doing.

Real users.
Real protocols.
“Finally an app that understands I'm managing multiple compounds. The PK curves alone are worth it.”
“I was recalculating reconstitution by hand every time. Dosi cuts that to five seconds.”
“The body map tracker made me genuinely more consistent with site rotation.”
