Does Clue have a workout feature?
Not in the sense most people mean. Clue is a rigorous, science-first cycle tracker, and it can show you which phase you are in, but it does not program workouts, build a training plan, or tell you what session to do today. It tracks; it does not coach. If you are looking for cycle-based workouts, Clue is the wrong tool for the job, and that is fine, because it was built for a different one.
What Clue is genuinely great at
Clue earned its reputation on rigor: clean data, a research-first approach, and strong handling of irregular cycles. As a way to understand and chart your cycle, it is hard to beat, and pairing it with a real training app is a perfectly good setup. See the fuller Phaes vs Clue comparison.
The gap: knowing the phase is not the same as training it
Knowing you are in your luteal phase does not tell you whether to do intervals or an easy run, how heavy to lift, or what to change because you slept badly. A tempo run can feel easy one week and brutal ten days later on the same plan. Turning the phase into the right session, progressed toward a goal, is the part a tracker leaves to you.
How Phaes turns your cycle into workouts
It prescribes the session, not just the phase
Phaes builds an adaptive running and strength plan from your real cycle and a daily check-in, so each day you get an actual workout matched to where you are and how you feel, not a label to interpret. See cycle syncing workouts.
Running and heavy strength, programmed together
Strength sits in the same plan as your runs, with day-level locking so neither gets dropped, and biases toward the windows where you build best. Through perimenopause and menopause that is how you protect bone and muscle while you keep training.
A common setup: Clue for the cleanest view of your cycle, Phaes for the workouts that respond to it. Cycle and symptom tracking are free in Phaes too, and you can grab a free 4-week sample plan below.
