Supports iPhone Duo, with expanded workout views and hands-free training when propped open. The best Norwegian 4x4 App on the App Store. Train the Norwegian 4x4 without watching the clock or guessing your effort. N4x4 reads your live heart rate — from Apple Watch, AirPods Pro 3, Garmin, WHOOP, Polar, or any Bluetooth monitor — and turns it into clear push, hold, and ease-off cues through every interval. When you finish, you see exactly how long you held the target zone, and how today compared with last time. Four 4-minute efforts, three easy recoveries. 33 minutes, warm-up and cooldown included. It trains VO2 max, the fitness marker most closely tied to how well you age, and it's one of the most studied ways to raise it. If you're going to invest time in your health, this is a strong place to start. HIT THE RIGHT ZONE • Target zones calculated from your own max heart rate • The number turns orange when you're below the zone and red when you're above, on both iPhone and Apple Watch • Spoken and haptic nudges when you drift out and stay out • A haptic countdown into every interval change: two taps, then the buzz USE THE SENSOR YOU ALREADY OWN • Apple Watch: install N4x4 on your wrist and heart rate streams automatically • AirPods Pro 3: the earbuds you're already wearing double as your heart rate monitor (iPhone on iOS 26) • Garmin (Broadcast Heart Rate), WHOOP (HR Broadcast), Polar, Wahoo, COROS, Powerbeats Pro 2, and any standard Bluetooth chest strap or armband • Wearing more than one? You choose which source wins • A built-in guide with exact, per-model setup steps EASY TO KEEP THE HABIT • Voice coaching through every interval, with the phone locked and your music ducked • Night-before, morning-of, and comeback reminders — each on its own switch • Weekly streaks, and a Live Activity on the Lock Screen and Dynamic Island FINISH WITH PROOF • Every interval charted against its target zone • Time in zone, time to zone, and a note per interval for your settings • Last session laid over today's, so progress is easy to see • Your usual workout — Cycle, Run, Kettlebells, and more — pre-selected when you save SEE THE PAYOFF • Your VO2 max trend from Apple Health • Training calendar, milestones, and full session history Works on the treadmill, rower, bike, stair climber, with kettlebells, or on the open road — any cardio that gets your heart into the zone. No account. No subscription. No ads. Your data stays on your device and in Apple Health. Start with one hard session a week. Add a second when you're ready.

Wonder is the first thing a busy life takes. The same commute, the same ceiling, a hundred remarkable things a day that stopped registering years ago. The capacity to be moved does not disappear. It just stops getting used. Awe Well puts it back to work. Once a day, one small invitation: something specific enough to actually do, written to fit your kind of wonder, and when you allow it, the weather and the hour you are in. Notice something, keep one line about what you noticed, and get on with your day. That is the whole practice. No streaks, no guilt, no scores. The research is unusually strong and the practice is unusually small. In study after study, people who feel awe regularly get out of their own heads, feel less pressed for time, and treat the people around them more warmly. You do not need a view for that. You need a minute. HOW IT WORKS - One invitation a day, written to fit your sources of wonder. When conditions outside aren't safe, Awe Well keeps you comfortably indoors. - Listen moments. Some days the wonder arrives as sound: a humpback singing in the open Atlantic, lightning at Jupiter caught by a passing spacecraft, dawn breaking over Yellowstone. - Somewhere new. Arrive somewhere you haven't been and Awe Well can point out one nearby thing worth a look, led by a true story about it. - Talk it through. Say what you noticed out loud, and a gentle voice companion asks the next question, until you find why the moment landed. - Reflect by typing or speaking. Your voice becomes editable text on your device, and no audio is ever kept. - On iPad, the journal becomes a reading and writing room. Sit back with what you wrote, or write with your pencil. - A journal of everything you noticed, searchable, newest first. - Save an invitation for later. The good ones come back around. - A gentle daily reminder at the hour you choose. - And for the days wonder feels far away, something quieter: grounding invitations with nothing to get right. NOBODY READS IT BUT YOU Your reflections belong to you. They sync to your account so they survive a new phone, and they are never sold and never used to train AI. Voice transcription happens on your device and no audio is kept. What the spoken companion is allowed to know and remember is a consent you control, change, or erase in Settings. Location is optional, approximate, and never stored. Delete your account and everything goes with it, right from Settings. THE PLAN Awe Well is free for 7 days, full practice, nothing held back. Then it's $7.99 a month or $39.99 a year. Cancel anytime in your Apple account settings and you won't be charged.
