Axis (TRT tracking app dev)
Hi everyone, I’ve been on TRT for about a year and I’ve tracked things pretty closely the whole time. I tried spreadsheets and a few tools, but nothing quite matched what I wanted, so I built this app for myself and I’m opening it up as a beta to share with the community.
Axis estimates testosterone levels hour by hour using a PK curve shape that includes absorption and elimination, instead of only simple half life decay. The point is to help you see what’s happening between injections and line that up with how you feel over time.
Current beta includes
• Estimated level curve with peak and trough timing
• Injection logging and history
• Symptom check ins to correlate with the curve
• Lab entry with optional calibration using your draw time and result
• Privacy first, no accounts and no cloud, data stays on your phone
What I’m looking for:
• People already on TRT who can use it for a week or two
• Bonus if you have recent bloodwork and the draw time so I can validate the estimates
• Honest feedback on what’s useful, confusing, or missing
Important note: This is a tracking and visualization tool only. The numbers are estimates and bloodwork is the truth. It doesn’t recommend dosing or ranges.
To join the iOS beta, axisprotocol.app and tap Join iOS Beta. That opens the TestFlight invite.
If you see Invite Code Required, install the TestFlight app first, then tap the iOS button again in Safari, not Chrome.
Android is in internal testing right now. If you’d like to join the beta, DM me your email and I’ll add you to the tester group and follow up with the install link.
FAQ
Does it recommend doses or ranges? No, it only visualizes what you log.
How accurate is it? It starts as a population model. Adding a lab with draw time lets the optional calibration improve fit for your response.
Do I need an account? No, everything is on device.
