The checks most men skip, done for you.
Real app screens, shown with a sample member.
Tap any screen to see it full size.
Ten seconds a day. A pattern in weeks.
Tap what’s true today: poor sleep, low energy, low drive, brain fog, joint aches, irritability, belly gain, night sweats, weak stream, up at night. One tap each, private to you and your coach.
- When several cluster across weeks, the coach says so once, plainly
- It tells you the cluster is worth checking, and that it’s measurable
- Zone 2 minutes tracked against 150 a week, on the same screen
Rule out the impostor first.
Snoring, gasping and unrefreshing sleep can look a lot like low testosterone. Tiller runs the eight-question screen doctors use, and answers some of it from your own data.
- Blood pressure and other answers filled in from what you’ve logged
- Breathing disturbances and blood oxygen from your ring, if you wear one
- A result you can take straight to your doctor
The right tests at the right age.
Upload a lab panel and out-of-range markers are flagged. Tiller shows which checks are due for your age, and drafts a lab request letter listing the tests worth asking about.
- Every year: blood pressure
- 45 and up: colon cancer screening
- 50 and up: the PSA conversation, ApoB, and a sleep study if you snore
- 60 and up: a bone density scan
Monitoring that doesn’t slip.
Log TRT with everything else you take. Tiller keeps the monitoring on schedule: the markers that drift, and when your next panel is due.
- Total T, sensitive E2, hematocrit, PSA and lipids, at least every 3 months
- Hematocrit and E2 watched, because they’re the two that drift
- Your dose is your doctor’s call
Tired isn’t a diagnosis. It’s a thread.
Tiller lines up your sleep, your symptoms, your ring and your labs, and tells you which thread to pull first.
A sample member. Tiller points out patterns in your own records. It does not diagnose.
- SleepLoud snoring logged on five nights in fourteen.
- WearablesYour ring flagged breathing disturbances on the same nights.
- SymptomsAfternoon fog and low energy, the day after each one.
- BloodworkTestosterone from June, near the bottom of the range.
- TillerTake the sleep screen to your doctor first. Poor sleep can pull testosterone down, so it’s worth ruling out.
Common causes first. Clear limits always.
The usual suspects
Sleep apnea, alcohol and a prostate that wakes you at night all look like a hormone problem. Tiller names them before any talk of testosterone.
Training that keeps up
Strength programs with a reason on every working weight, zone 2 tracked alongside, and meal plans to match. See everything on the athletes page.
Clear limits
Tiller is a coach, not a TRT clinic. It points out patterns and helps you prepare. It doesn’t diagnose, treat or prescribe, and it tells you when to see someone.
Before you start.
Is this a testosterone clinic?
No. Tiller doesn’t prescribe anything. It tracks how you feel, checks the common causes, and gets you to your own doctor with better questions.
I’m already on TRT. Is Tiller still useful?
Yes. Log it with everything else you take, and Tiller keeps your monitoring bloodwork on schedule. Dosing is your doctor’s call.
Do I need bloodwork to start?
No. Start with the daily check-in and your sleep. Add labs whenever you have them, and Tiller flags what’s out of range.
Is the check-in private?
Yes. Your taps feed your coach and your own reports, nothing else.
