QuietTap is a haptic metronome for your wrist. It delivers a steady, rhythmic pulse at a pace you choose — giving your nervous system something constant to hold onto when everything else feels uncertain. A steady haptic pulse gives your body something to lock onto, naturally slowing your breath and heart rate. Unlike audio tools, QuietTap works silently through touch — on your wrist or in your hand, wherever you are. Quick start presets for Calm, Focus, Energise and Sleep let you start with one tap. After your session, see how your heart rate changed over time. No sound. No notifications. Just rhythm.

Verdict
The clearest difference is in-app purchases: BDA Peng at none against QuietTap's 1. QuietTap's advantage is update cadence (daily vs every 5 months). On price, ads, device support and iOS requirement there is nothing between them.
