This page is designed to help you find out whether Knightify Pulse is good and if it is the right choice for you.
Pulse is a private couples wellness app for iPhone and Apple Watch that turns the signals your watch already collects into one gentle, human sentence for your partner — never a number, never a verdict.
How it works Pulse reads sleep, resting heart rate, heart rate variability, movement and recovery from Apple Health, compares them against your own rolling baseline on your device, and turns the result into a short cue your partner can act on, such as "A calm evening might mean a lot today." Raw health data is processed locally and never leaves your phone.
What's inside - Today's cue — one sentence about your partner's day, plus two or three concrete suggestions - Insights — weekly and monthly trends, a connection streak, and patterns Pulse notices over time, each linked to a source such as the NIH, the American Heart Association or the Cleveland Clinic - Question of the day — a shared prompt where your partner's answer stays hidden until you write your own - Together — end-to-end encrypted chat, photos and GIFs, "Hold to Feel" presence, and one-tap gestures like a thinking-of-you tap - Shared life — an Our Story photo timeline, a shared wishlist, date planning and a shared calendar - Everywhere else — notification centre, home screen widget, Live Activity and a dedicated Apple Watch app - Your data — versioned consent, pausable sharing by category, data export and deletion, with no ads, no third parties and no data sold
Pulse also connects with WHOOP. It's built by Knightify FlexCo in Vienna, Austria, and is free for both partners, with no ads.

Pulse reads the signals an Apple Watch already collects (sleep, resting heart rate, HRV, movement, recovery), compares them only against the wearer's own rolling baseline, and turns the result into a single human sentence for their partner, such as "A calm evening might mean a lot today." It never shows a number, a chart or a verdict, and the raw health data never leaves the wearer's phone — there is no cloud AI and no third-party analytics in the loop. Cues also expire at midnight, so there is no archive of anyone's wellness to scroll back through.
Most of Pulse's neighbors are either fitness trackers (WHOOP, ŌURA Ring, Fitbit) that report your own numbers back to you, or general couple apps (Couple.me, Between, Happy Couple) built around messaging and shared calendars. Pulse sits in between: it actually connects to your Apple Watch data, but instead of handing your partner your heart rate or sleep score, it converts that into one caring sentence and a couple of suggestions, with the raw numbers enforced — in code, not just policy — to never leave your phone. It also has no history view, no cloud AI, no ads and no data sold, so there's nothing to be surveilled or profiled. For a couple that wants a partner to say "go easy on me tonight" without oversharing their biometrics, Pulse does that in a way a generic tracker or chat app doesn't.
Pulse is built for couples who own an iPhone, and ideally an Apple Watch, and who want a gentler way to stay attuned to each other day to day, particularly when schedules, distance or ordinary bad days make it hard for one partner to explain what's going on. It's aimed at privacy-conscious users: people who like the idea of a partner-aware app but would never want their own heart rate, sleep or cycle data actually leaving their phone. It's currently iOS/watchOS only, shipped in English and German, and free for both partners in the relationship.
Couples rarely fail on the big, dramatic days; they erode on ordinary ones, where one partner is quietly depleted, the other reads it as distance, and neither has the energy left to open the conversation that would fix it. The team at Knightify FlexCo, a small studio in Vienna, noticed that an Apple Watch has been measuring the raw ingredients of that gap all along, sleep debt, resting heart rate, HRV, movement, without anyone turning it into something a partner could actually act on, and without it becoming surveillance. Pulse was built around three refusals: no numbers ever cross between partners, no archive of another person's body, and no verdict, only an opening. Every cue is a single human sentence, deleted at midnight, sourced to real health references, and enforced in code rather than policy.
Pulse is a native iOS and watchOS app. It reads Apple HealthKit data (sleep, resting heart rate, HRV, movement, respiratory rate, blood oxygen) with read-only, versioned consent, and builds each person's rolling baseline and cue entirely on-device, with deterministic rule-based scoring rather than any large language model or cloud AI service. Chat, photos and the daily question use CryptoKit with AES-GCM for message content and Curve25519 for key agreement, with the private key held only in the user's iCloud Keychain. A self-hosted WebSocket relay on Knightify's own infrastructure carries already-encrypted chat traffic and typing/read-receipt signals; it is not a third party and stores nothing. There are no analytics, ad or tracking SDKs anywhere in the app.
