Pacing that sees tomorrow.

For most people, the body shifts measurably in the day or two before a crash. HRV drifts down, resting heart rate creeps up, sleep gets worse. Heedly learns what your normal looks like, and when your data starts moving the way it usually does before your crashes, it gives you a quiet heads-up so you can rest early. Your check-ins teach it too: if you tag "social interaction" and crash two days later, and that keeps happening, Heedly connects the two and learns to warn you earlier next time.

Currently, Heedly works with any device that syncs to Apple Health, which covers nearly all of them: Oura, Apple Watch, Garmin, Fitbit, Polar, Withings and more. Heedly launches on iPhone first, with direct device connections and Android support coming after launch.

You can use Heedly without one. The daily check-ins are enough for it to learn your patterns and triggers, like which activities tend to show up as a crash a day or two later. What you'll miss is the body data: the early signals like HRV and heart rate shifts often start before you feel anything, so without a wearable the warnings lean on what you log rather than what your body shows.

No. The daily check-in is three questions and takes about 30 seconds, designed to be doable lying down. You can skip any day without breaking anything, and on the worst days there's a one-tap "I'm in a crash" log instead. More check-ins help Heedly learn faster, but nothing ever guilts you about a missed day.

Heedly uses a transparent statistical model that runs entirely on your phone, built around your own baselines, and your raw health data never leaves your device.

Heedly only uses an optional AI language layer that rewords already-computed summaries into friendlier sentences. It never sees your raw data or anything that identifies you, it runs through a service with a zero-retention policy, and you can turn it off completely and get the same patterns in plainer wording.

You do. Your data is private by default, you can export or delete it whenever you want.

No, never. Heedly knows what graded exercise advice has done to this community. It will only ever suggest doing less, sooner.

Heedly is currently building its beta testing group, and testing is planned to start in fall 2026. The app is planned to launch in late 2026 or early 2027, available on the App Store and directly through this website. Join the waitlist to be part of the beta program and get launch updates.
