Never miss a dose.
Never guess your levels.
Track injections, visualize real-time concentration curves, and get smart reminders — all on your device.
Tracking injections shouldn't be this hard
Most people rely on memory, notes apps, or spreadsheets. That leads to...
Missed Doses
Forgetting when your last injection was or when the next one is due.
Guessing Levels
No way to know if you're at peak, trough, or somewhere in between.
No History
Nothing to show your doctor at appointments. No patterns to learn from.

"Finally an app that doesn't try to do everything. Stiq does one thing — track injections — and does it perfectly."
"The concentration curves are a game changer. I can actually see when I'm at trough and adjust my schedule accordingly."
"I love that my data stays on my phone. Every other health app wants to upload everything to the cloud. Not Stiq."
Frequently asked questions
Yes! The free tier lets you track one medication with basic reminders. Upgrade to Premium or Pro for unlimited medications, concentration curves, cloud sync, and more.
By default, all your data stays on your device. Nothing leaves your phone unless you enable cloud sync with the Pro plan. We take your privacy seriously.
Stiq supports any injectable medication with customizable half-life curves. Common use cases include testosterone (cypionate, enanthate), insulin, biologics, and more.
Stiq uses pharmacokinetic modeling to estimate the concentration of your medication over time based on the dose, injection site, and the drug's half-life. These are estimates, not medical advice.
Premium and Pro users can export their full injection history as CSV. This is helpful for sharing with your healthcare provider.
Currently, Stiq is available as a Progressive Web App (PWA) that works on any device with a modern browser. Native mobile apps for iOS and Android are coming soon.
No. Stiq is a personal health tracking tool. It does not provide medical advice, diagnosis, or treatment. Always consult your healthcare provider for medical decisions.
