Privacy-first fitness analyzer with built-in BLE/GPS recording and group sharing
About this app
PAIesque is a privacy‑focused fitness tool that records workouts, analyzes training load, and lets you share live sessions.
Record heart‑rate and GPS data directly from BLE chest straps or other heart‑rate sensors. No third‑party app required. Multiple sensors are supported, and recordings are saved as GPX/CSV.
Analyze your training on an interactive map and zoomable chart. View live metrics while a recording is active, or choose a date range to inspect past sessions. The map track is colored by heart‑rate zone, and you can compare multiple devices side‑by‑side.
Share your live status and completed recordings with a group via a simple self‑hosted PHP server. See other group members on the map in real time, and browse their past sessions just like your own.
All training‑load metrics come from published, peer‑reviewed science:
• TRIMP methods — Banister, iTRIMP, LT‑TRIMP, and PAI‑inspired formulas.
• EWMA & ACWR — rolling loads and injury‑risk monitoring.
• Recovery metrics — RHR and HRV (RMSSD) calculated from your sleep window.
• Polarized training — zone distribution and achievement tracking.
Data stays on your device. No accounts, no cloud uploads, no tracking.
Health Connect is needed if you want to import heart‑rate data from other apps (Gadgetbridge, Garmin, Polar, etc.).

- # Release Notes – v89
- This updater ecords all selected BLE devices (even if they connect later), falls back to a phone‑GPS device when none are selected, saves and restores the map camera across pauses, updates the live status time every second, shows only recording remote devices on the map, and fixes several crashes and stale‑data issues.

- # Release Notes – v88
- This update adds controls for how many days of past recordings are shared when joining a group, enforces a maximum group size reported by the server, and automatically cleans up old group directories on the server. Remote devices that stop recording are now hidden from the live view. The map can show all device tracks or only the selected one, and all tracks now use the same zone colours. The recording screen updates location values every second and fixes a stale GPS st

Installation Guide
Open Settings on your Android device
Go to Security → Unknown sources (or Install unknown apps)
Enable "Allow from this source" for your browser or file manager
Open the downloaded APK file from your Downloads folder
Tap "Install" and wait for installation to complete
Launch the app from your home screen
Make sure to re-enable Unknown Sources restrictions after installation for security.
How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be org.ojrandom.paiesque is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 89 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall PAIesque first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of PAIesque, and a listing is removed when the evidence for it stops holding up.
