Introduction
The new Nothing CMF Watch 3 Pro just launched and tech enthusiasts are asking: Does it really work well with the iPhone? Featuring a larger AMOLED display, built‑in ChatGPT AI coach, dual‑band GPS, IP68 rating, and an impressive 13-day battery life, the Watch 3 Pro has serious buzz. But if you're an iOS user, here’s what you really need to know.
1. iPhone Compatibility is Solid
Yes, the CMF Watch 3 Pro pairs seamlessly with the Nothing X iOS app, unlocking message preview, health data, and call alerts. Reviews and user reports confirm it works very well with iPhone 15 models. While direct message replies are limited and Apple Health integration may be partial, key features operate reliably (Reddit r/NOTHING).
2. New AI-Powered Features
With ChatGPT unlocks, the Watch offers voice coaching, guided breathing, AI transcriptions, and quick replies. Fitness enthusiasts benefit from dual-band GPS accuracy, 130+ sports modes, and a robust heart rate sensor designed for different skin tones (9to5Google).
3. Incredible Battery Life & Display
The Watch’s 1.43-inch AMOLED display with ultra-thin bezels delivers excellent clarity and brightness. With typical use, expect up to 13 days of battery, or around 4.5 days if Always-On Display (AOD) is enabled, much longer than most competitors offer (TheVerge).
4. Durable Design & Health Tracking
Boasting IP68 water and dust resistance, the CMF Watch 3 Pro handles sweat, splashes, and light showers. Key health sensors include advanced heart rate, SpO₂, stress tracking, sleep & menstrual insights all tightly integrated into the refined Nothing X app.
5. Limitations iOS Users Should Know
Not compatible with Wear OS and has no access to third-party watch apps or complex integrations.
Users report no in-app message reply on iPhone, and some uncertainty around Apple Health integration despite link-ups.Â
Some early CMF reviews highlight connectivity issues with past models, though many say the Watch 3 Pro has improved in recent firmware updates.Â

Final Verdict
If you’re a tech-savvy iPhone user hunting for a budget-friendly smartwatch with AI coaching, outstanding battery life, and precise fitness tracking, the CMF Watch 3 Pro delivers compelling value. While it doesn’t offer the full Apple Watch experience, its iOS pairing is solid and worth considering.
