The Best Wearables for Biohacking in 2025

2 Introduction

1 Biohacking isn’t fringe anymore — it’s mainstream.

2 We’ve gone from step counters to full-body dashboards.

3 Whether you’re optimizing sleep, tracking blood sugar, or chasing peak cognition, 2025’s wearables are more advanced — and more personalized — than ever.

3 WHOOP 5.0+

Focus: Recovery, strain, sleep

Why biohackers love it:

1 Continuous HRV, resting heart rate, skin temp, and respiratory rate.

2 No screen = distraction-free.

3 Sleep coach + strain coach powered by AI.

Bonus: Monthly insights, real-time coaching, and now FDA-cleared pulse oximetry.

4 Oura Ring Gen 4

Focus: Sleep, readiness, cycle tracking, HRV

Why it stands out:

1 Still the most discreet wearable packed with sensors in a ring.

2 New: stress detection, blood oxygen, and improved period prediction.

3 Works beautifully with minimalist or tech-averse lifestyles.

5 Ultrahuman Ring AIR

Focus: Metabolic health, fitness, recovery

Why it’s rising fast:

1 Combines metabolic scoring + movement patterns.

2 Works with the Ultrahuman M1 glucose monitor.

3 India-based startup with a global reach and gorgeous UI.

6 Levels / Supersapiens (CGMs)

1 Focus: Real-time glucose tracking

2 For: Keto fans, intermittent fasters, athletes, and longevity buffs

3 How it works: Pairs with a CGM (like Abbott Libre or Dexcom) to show how food, stress, and exercise affect glucose in real time.

4 New in 2025: Smaller sensors, longer wear time (up to 21 days), and deeper AI insights.

7 BioStrap EVO

Focus: Biometrics, respiratory data, sleep lab-grade tracking

Why biohackers dig it:

1 Clinical-level data at home.

2 Tracks blood oxygen, pulse waveform, SpO2, and advanced HRV metrics.

3 Now integrates with AI-based wellness protocols and remote coaching.

8 Apollo Neuro

Focus: Nervous system regulation (vibes, literally)

What makes it unique:

1 Delivers gentle vibrations to help you shift into focus, calm, sleep, etc.

2 Worn on wrist or ankle.

3 Backed by neuroscience — not just placebo.

9 Dreem 3 / Muse S (2025 Edition)

Focus: Sleep neurotech

Why they’re wild:

1 EEG-based headbands that track brain activity during sleep or meditation.

2 Dreem helps with insomnia and lucid dreaming.

3 Muse integrates with guided meditation and biofeedback tools.

10 Garmin Fenix 8 / Epix Pro

Focus: Endurance training, full-body metrics

Ideal for: Runners, triathletes, hikers, and outdoor athletes who biohack like warriors.

Features:

1 VO2 max, HRV, pulse ox, GPS, stress, body battery, and real-time stamina estimates.

11 Bonus Picks for Hardcore Hackers

1 Neurable: Brain-computer interface headphones for focus tracking.

2 Happy Ring: AI-powered mental health monitoring.

3 Lumen: Breath analyzer for metabolism & fat-burning zone detection.

4 Smart mouthguards / earbuds: For hydration, EEG, and even core temp (yep, it’s getting sci-fi).

12 Choosing the Right Stack

Consider your goals:

1 Better sleep? → Oura, BioStrap, Dreem

2 Stress + focus? → Apollo, Muse, Neurable

3 Metabolic health? → Levels, Lumen, Ultrahuman

4 Recovery & training? → WHOOP, Garmin, BioStrap

5 Most biohackers are now stacking wearables ring + CGM + vibration tech, for example.

Conclusion

Wearables in 2025 aren’t just trackers — they’re real-time feedback loops for optimizing your mind and body.
