App-connected sunrise alarm with SleepMapper coaching and RelaxBreathe for sleep onset

Philips SmartSleep HF3670: The connected sunrise alarm with personalized sleep coaching

At $200, the Philips SmartSleep HF3670 is the most advanced wake-up light in Philips' lineup. The clinical sunrise simulation of the HF3520 is present, and the HF3670 adds SleepMapper app integration for personalized sleep coaching, RelaxBreathe guided breathing to help with sleep onset, and FM radio with 5 nature sounds. For buyers who want Philips' full ecosystem — data, coaching, and connected control — the HF3670 is the top-of-line option.

What works

SleepMapper app provides personalized sleep coaching based on your sleep patterns and wake data. The app suggests changes to routines, timing, and environment to gradually improve sleep quality. This coaching layer differentiates the HF3670 from the HF3520, which provides excellent hardware without data collection or coaching.

RelaxBreathe feature guides paced breathing exercises for sleep onset — a guided audio prompt helps you slow breathing, reduce arousal, and fall asleep faster. Clinical research supports paced breathing for sleep onset improvement.

Sunrise and sunset simulation are both present — the gradual light increase for waking and gradual light decrease for falling asleep. The combination addresses both ends of the sleep cycle.

FM radio and 5 nature sounds provide comprehensive auditory wake options.

What doesn't

$200 is the most expensive wake-up light in this comparison, matching the Hatch Restore 2. The HF3520 at $130 delivers the core clinical sunrise function for $70 less; the app features of the HF3670 are the justification for the premium.

App connectivity can be unreliable — this is noted in the product data as a known issue. Some users report frequent disconnections and setup difficulties. For a product whose premium features require the app, connectivity issues undercut the value proposition.

Who should buy this

The buyer who wants Philips' full clinical ecosystem — sunrise simulation, personalized coaching, and guided sleep exercises — and is comfortable with app-dependent features.

Who should look elsewhere

Core clinical sunrise without app: Philips HF3520 ($130). Smart features different ecosystem: Hatch Restore 2 ($200). Mid-range without app: Lumie Spark 100 ($60). Budget: JALL ($30).
