Sleep restores your Aura. Movement takes on your Restlessness. Data2Dao is BigData Cultivation: your health data becomes Aura, and every workout becomes a kung fu battle. Prop up your iPhone, let the camera track every stretch, squat and push-up, and land each rep as a hit on a monster. Build combos, clear stages, rise through the realms, and let sleep and rest count too. A few minutes a day, beside an orange cat. UNDERSTAND TODAY'S CONDITION Connect Apple Health to turn available sleep, heart rate, HRV and activity records into game indicators such as Aura and Restlessness. Reflect on your condition and plan movement and rest. Some insights need enough data from compatible sources. Screen Time requires separate permission (iOS 18 or later); once allowed, late-night scrolling builds up your Restlessness. WHAT TO TRAIN TODAY? YOUR BODY DECIDES Based on today's condition and recent training, you get today's stage: side stretch, jump claps, squats, push-ups, high knees. From 3 minutes, from light to advanced. Move through chapters like a level path, keep your streak on record, and take leave on rough days. FIGHT BESIDE THE CAT, EVERY REP COUNTS Set your phone down in front of you. The camera recognizes each movement: every completed rep takes a bite out of the monster's health, your combo keeps climbing, and a combo trend shows how steady you are. See yourself in a small window while you and the cat fight on screen. No wearables, no accessories, just an iPhone. TRAINING, REST, INSIGHT, ALL PART OF YOUR PATH Runs, rides, coffee, mood, a body heat map, today's check-in photo and workouts from Apple Health all flow into your Path timeline. Rest days are part of the practice too. Look back at your trends and find your rhythm. FROM LOOSENING UP TO REAL KUNG FU Open Roc Wings, Lean Muscle Art and Wave Treading for upper-body, core and lower-body practice, plus Baduanjin and guided calisthenics. Practice form by form; each manual tracks its level and total reps, and mastering one form unlocks the next. A FEW MINUTES A DAY, YOUR STREAK IS YOUR PRACTICE No burnout required. One stage is 3 minutes, one stage a day. Keep the streak going to grow your Power and rise through the realms, from Mortal to First Steps, with the Cat Master beside you.

Verdict
The clearest difference is update cadence: Data2Dao at every 3 days against Sundialbum's every 3 weeks. Sundialbum's advantage is iOS requirement (15.0 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.
