Mojo: Testosterone Tracker: Track habits, Improve hormones

Thanks for checking out Mojo — really excited to launch this. Why I built it: Over the past couple of years, I noticed a trend — a lot of guys in their 30s and 40s (friends, coworkers, myself included) were hitting a wall: low energy, reduced motivation, mood dips, poor recovery after training. Many ended up getting bloodwork done and learning their testosterone was lower than expected. But once you find that out... then what? There’s a ton of conflicting advice online. Some of it’s solid, a lot of it’s fluff. And there’s no simple, science-backed way to track the habits that influence testosterone and actually see what’s helping over time. Enter Mojo. Mojo is a minimalist, private iOS app that helps men track the key lifestyle factors that impact hormones, mood, energy, and recovery — and surfaces personal patterns over time. You check in once a day — sleep, stress, libido, energy, workouts, alcohol, food, supplements, etc. Mojo gives you a daily vitality score based on your inputs and overlays it with trends across key “pillars” like hormonal balance, physical recovery, and mental clarity. It then surfaces correlations over time — for example: “Your libido tends to be 20% lower the day after drinking” or “You feel most energetic after 3+ workouts per week.” You also get access to concise, science-backed education inside the app — no bro-science, just practical, referenced guidance on how lifestyle impacts testosterone and long-term vitality. No account. No server. No tracking. All data stays on your device. Apple Health integration for importing workouts, sleep, etc. One-time purchase — no subscriptions, no upsells, just a straightforward tool. Designed to be fast and frictionless — check-ins take under 30 seconds. Mojo isn’t a gimmick. It’s not going to fix your hormones overnight — but it will help you build awareness, track your consistency, and see how your daily habits are influencing how you feel. Over time, that feedback loop becomes incredibly powerful. If you’re into quantified self, digital health, or just knowing how your body is doing — I’d love your feedback. I’m here all day to answer questions, share how I built it, or discuss what’s next. Thanks again for checking it out!
