This is a straightforward app to help you achieve a chosen mind-state by generating what are known as "binaural beat audio waves" through your headphones, either from your iOS device or your Apple Watch. Depending on the frequency that you pick, based on the chart included in the app, it can potentially help with sleep, meditation, relaxation, or even for getting a short burst of energy. I have used similar apps for a while and have found them useful in helping me relax, or helping me float into a creative mood - Except most are overloaded with features that I never use and also cost money, have in-app purchases for "special programmes" and so on. So I decided to build one that does the same, works offline, has no ads or spying, works well, and is free. There's also an Apple Watch app included which you can use if you're mediating or relaxing away from your phone. As such, this app just generates the binaural frequency audio hum, and some optional white or brown noise to help mask outside sounds. You can then put it in the background and combine its audio with any other sound generator you like, or play music, radio, and so forth. All it does is to create the useful brainwave frequency, and then it gets out of your way.

Most men don’t realise it, but after age 30, testosterone levels begin to decline — slowly, silently, and often with noticeable effects. You might feel more tired than usual, lose motivation to train, struggle with sleep, or find your mood dipping for no obvious reason. These changes can be subtle at first, but over time, they add up. Mojo helps you spot the patterns, take control, and feel like yourself again. It’s not about gimmicks or shortcuts — it’s about understanding how your daily habits affect your hormones, energy, and overall vitality. Track the habits that matter Mojo gives you fast, frictionless daily check-ins for the key lifestyle factors that impact male hormones — including sleep, stress, libido, energy, training, alcohol, supplements, and more. The process takes less than 60 seconds a day and helps you stay consistent without overthinking it. Every data point you enter is stored locally on your device. There’s no account to create, and no personal information ever leaves your phone. Your health is your business — we keep it that way. Understand how your habits affect your health Mojo doesn’t just collect data — it helps you learn from it. Your inputs are analysed and distilled into a daily vitality score, so you can get a simple, high-level view of how you’re doing. Over time, Mojo surfaces meaningful correlations between your lifestyle and your score — helping you identify what’s helping or hurting your recovery, drive, and energy. You’ll start to see things like: • How late-night alcohol impacts your mood the next day • Whether consistent sleep boosts your libido • How training too hard without recovery tanks your energy Mojo turns gut feelings into clear, measurable insights — so you can make smarter choices without the guesswork. Built for consistency and momentum Improving your hormones and performance is all about consistency. Mojo helps you stay on track with streak tracking, weekly summaries, and motivational nudges based on your real data. It’s not just about logging — it’s about building habits that compound over time. You’ll see how your average vitality is trending week to week, and get rewarded for showing up — even on days where you’re not at your best. Powered by science, not fluff Forget the noise. Mojo gives you concise, referenced articles that explain the science behind how lifestyle factors like sleep, diet, stress, and exercise affect testosterone. No clickbait, no bro-science — just clear, actionable information grounded in peer-reviewed studies. You’ll also get bite-sized daily tips that help you improve over time — small tweaks that can make a real difference when applied consistently. Apple Health integration Mojo can optionally sync with Apple Health to pull in data like your sleep, workouts, and step count — helping you stay accurate without logging everything manually. You remain in full control of what’s shared. We don’t store or sell your health data — ever. Who it’s for Mojo is designed for men who want to: • Boost their energy, focus, and mood • Improve sleep, libido, and motivation • Understand how daily habits impact hormone health • Build sustainable routines for long-term performance • Take control of their wellbeing — naturally, without prescriptions If you’re starting to feel the slow drop in vitality, Mojo helps you reconnect the dots, rebuild your baseline, and optimise your health from the ground up.
