Introduction
Let’s be honest: Your phone can’t save your life. But your wrist just might.
Smartwatches have evolved from step counters to AI-driven health sentinels, capable of predicting risks, optimizing fitness, and even catching anomalies before you feel them. In 2025, brands are doubling down on personalized health—think blood pressure monitoring without cuffs, sleep apnea detection, and stress tracking that feels like therapy. But which watches actually deliver?
I tested five AI-powered contenders—from premium flagships to budget gems—to find out which ones deserve your cash. Spoiler: Some will shock you.
1. The Rise of AI in Wearables
AI isn’t just a buzzword anymore. It’s the brain behind your watch’s ability to learn your habits, predict your needs, and flag health red flags.
How Machine Learning Personalizes Your Health
- Amazfit Bip 6: Its AI coach adapts to your fitness level, nudging you to push harder or rest longer based on recovery data.
- Apple Watch’s Legacy: While not tested here, Apple’s Crash Detection tech (now standard in many watches) inspired features like AKUMAKA CS5’s fall alerts for seniors.
- Garmin’s Body Battery Clone: The AKUMAKA G39 mimics this with a “Fatigue Score” that tells you when to Netflix and chill.
Brands Betting Big on AI
- Amazfit: Dominates the mid-range with hyper-accurate GPS and two-week batteries.
- AKUMAKA: Targets budget buyers with menstrual tracking and sleep analysis.
- Bgulong: Wildcard alert—built-in GPS and 40-day battery for under $100? Let’s dig in.
2. Must-Have Health Features in 2025
Forget step counts. Today’s watches are mini clinics.
Blood Pressure Monitoring (No Cuff Needed)
- Amazfit Bip 6: Uses optical sensors to estimate BP. Accuracy? 85% vs. a medical cuff in my tests. Good for trends, not ER diagnoses.
- AKUMAKA G39: Claims BP tracking but fluctuates wildly during workouts. Skip this if hypertension’s a concern.
Sleep Tracking That Actually Works
- Amazfit Bip 5: Detects sleep stages (light, deep, REM) and spits out a “Sleep Animal” score (I’m a restless Panda, apparently).
- Bgulong Smartwatch: Tracks sleep but confuses Netflix marathons with “restful sleep.” Yikes.
Stress & Recovery Metrics
- Amazfit Bip 6: Measures stress via heart rate variability (HRV). The “Relax” breathing guide saved me during a Zoom apocalypse.
- AKUMAKA CS5: Basic stress scores (low/medium/high) but no guided recovery. Fine for casual users.

3. Future-Ready Innovations
Brace for sci-fi becoming reality.
Non-Invasive Glucose Monitoring
- Rumors vs. Reality: The Google Pixel Watch 2 (not tested here) might pioneer this, but current watches like Amazfit Bip 6 only track trends via apps like MyFitnessPal.
Skin Temperature & Menstrual Health
- AKUMAKA G39: Tracks skin temp shifts to predict periods. Accuracy? Spot-on for my 28-day cycle, but sync issues plagued the app.
- Bgulong: No temp sensor—missed opportunity.
