Watch the number come down.
Every shot, weigh-in, and side effect, folded into your estimated medication level. One calm, private read of the whole thing.
Free for personal use. No ads, ever.
The idea
See what's working, and keep going.
Uptake brings your shots, weight, and how you feel into one clear picture, so the week-to-week effort adds up to something you can actually see.
What you track
Four things. One read.
The stuff that actually moves week to week, and the one number nobody else bothers to show you.
- 01
Shots and sites
Log every dose. Uptake suggests the next injection site, so you rotate without thinking about it.
- 02
Weight
A trend that reads at a glance, anchored to where you actually started, not your first weigh-in.
- 03
How you feel
Nausea, appetite, energy, on a 0 to 10 scale. Patterns surface right after a dose change.
- 04
Medication level
An estimate of how much is in your system today. The number nobody else shows you.
The one with real math
The number nobody else shows you.
Every shot builds on the last. Uptake models absorption and clearance (a one-compartment curve summed across your whole history) to estimate your medication level on any given day.
Estimated levels are a model, not medical advice.
Private by default
Your data is yours. Full stop.
Every row is locked to your account and never readable by anyone else. No ads, no selling, no sharing. Export everything to CSV whenever you want, or delete it all in one tap.
