Lento Pulse: Less noise. More calm.

Overview

Lento Pulse is designed for anyone who wants a simple way to carve out a moment of calm at the end of a busy day using their Apple Watch. Instead of following complicated routines or tracking stats, it offers a tactile, heartbeat-like pulse for up to 30 minutes. You set the rhythm speed yourself, ranging from 45 to 100 beats per minute, and choose from nine different vibration patterns to focus your attention and relax without distractions.

I liked how plainly the site explains what it isn’t. The BPM is a pace you set, not a reading of your heart, and the rhythm never changes to follow your pulse. It isn’t a breathing exercise either, and the terms are clear it’s not a medical device or a treatment for sleep or heart problems.

Privacy is simple: no account, no internet connection, no analytics or tracking. It can optionally read your latest heart rate from Apple Health to show on the setup screen, but the site says that number stays on the watch. You need watchOS 26 or later. The site doesn’t list a price, saying only that whatever Apple shows at checkout applies, and it’s made by a solo developer, Mathias Larsen of mdsolutions.

We went through the site and it says the app runs fully on Apple Watch with no tracking or accounts required to use the quiet pulse. I checked the homepage FAQ and the terms, then tapped Find on App Store to check the app is actually listed and see what it costs.
