BRING YOUR A-GAME. ANYWHERE. KIN is the next gen training diary โ€” built to find what truly drives your best performance and turn it into action. Making every day better. Built with elite athletes, KIN combines the proven ritual of the training diary with your wearable data, voice check-in and unique real-time performance intelligence. 30 seconds a day. Instant value back. Check in by voice in the morning and after training, competition or whenever something matters. Capture what your wearable can't see โ€” how you felt, what happened, what worked, what didn't. KIN connects that context with your training, recovery and biometric data to uncover the patterns behind your performance. Giving you a distinctive performance edge. Every check-in delivers immediate value. Your performance edge compounds. The longer you use KIN, the more it understands what drives your performance. 7 days is an advantage. 90 days is unfair. THE TRAINING DIARY FOR A NEW ERA The training diary has always helped athletes reflect on what happened. KIN goes further. Much further. It connects: โ€ข How you feel โ€ข How you train โ€ข How you recover โ€ข What happens in your life โ€ข How you actually perform Then turns those patterns into actionable insight. In real time. Unlocking peak performance. Wearables are excellent at measuring sleep, recovery, activity and training. But performance is shaped by more than biometrics. Pressure. Confidence. Travel. Work. Motivation. Relationships. Preparation. What happened yesterday. What matters tomorrow. KIN brings it together. Your wearable has the data. You have the context. KIN finds your edge. WHAT KIN GIVES YOU Daily performance insights Every check-in gives you something back โ€” insights you can act on today. A smarter training diary Log training and performance naturally by voice, without forms or endless metrics. Your complete performance history See training, competition, recovery and context together โ€” not in separate apps. Patterns only you have KIN learns what consistently lifts your performance and what quietly holds it back. A compounding performance edge Every day adds context. Every performance sharpens the picture. BUILT BY ELITE ATHLETES KIN was created with professional athletes around one question: What actually drives peak performance when it matters most? Now that same Performance Intelligence becomes accessible to all high-performers serious about performing at their best โ€“ whatever the opportunity. KIN finds your edge. Making every day better. Now bring your A-game. Anywhere.

About

Curious Life

Read full description

Curious Life turns a live measurement into music, light and games you can practise with. On your phone runs a scientific instrument: a stream of random events drawn from the tiny timing jitter of the device itself, in the lineage of the Princeton PEAR laboratory. Everything in the app is made from it, live. Whether attention can lean on that stream is a century-old question. Here it becomes something you can hear, play, and keep a record of. NOTES FROM THE FIELD Music written live by the field. Five soundscapes: an open-air sound garden, Memory's slow water and soft light, a choir in a stone room, plucked strings, and Mosaic, where the instrument's own bits ring a marimba. Every note comes from the measurement; nothing is recorded or looped. STAR TRIP AND THE EXERCISES Fly a star across deep space at the altitude of the live reading and catch the golden rings. The Oscillator, Chaos vs Coherence, Synchrony, the Moon, the Orchestra and more: living exercises, all driven by the same measurement. THE PULSE Link a Polar chest strap, a watch, or a Muse headband, and your heart and brain join the field: heart rhythm and coherence, the brain's bands, and music played by your own readings. Heart, brain and the random source record together on one clock, through a locked screen. Export everything as open files whenever you like. THE AMBIENT TAB Let it play while you live. The Pulse, Notes from the field and Ambient's sixteen night voices, with a dawn alarm that wakes you with your own field. The music keeps playing with the screen locked, and stays honest: it rides the real measurement, or it stays silent. FREQUENCY TUNING AND THE SUN MEDITATION A frequency generator with carriers and pulses for grounding, focus and rest, now including the Schumann resonance, the Earth's own 7.83 Hz hum, raised five octaves so you can hear it. And the sun meditation: five minutes at noon, turning to the sun. YOUR RECORD Every session builds your personal record, placed against the whole field of practitioners. No account is needed; sign in with your email to carry your record across devices. NOTHING WATCHES YOU No microphone, no motion sensors. The camera and photo library are asked for only when you open a picture in Synaesthesia; Bluetooth and Health only when you choose to connect a device. Heart, brain and picture data never leave your phone. It is an instrument and an open experiment: whatever the data shows, it shows. Curious Life is an experiment and a practice, not a medical device. It makes no health claims, and a sound cannot carry the Earth's field or lock you to it.
