## What is Tracerlink?

Tracerlink brings live vario data from your UltraBip, BlueBip or XC Tracer directly to Apple Watch.

Built for paragliding and hike-and-fly pilots, Tracerlink keeps your cockpit light: connect your external BLE vario, start your flight and read the key values on your wrist without using an iPhone cockpit in the air.

The watch-first display is designed for short glances: large numbers, clean layouts and a Focus Mode that gives one selected value more room on screen. Optional haptic feedback can signal climb with subtle taps, while Workout integration helps keep the display active and tracks flight duration.

Why pilots use Tracerlink:

- Wrist-only flight display: live vario values directly on Apple Watch
- Light setup: no phone cockpit needed in flight
- Quick connection: connect UltraBip, BlueBip or XC Tracer from the watch
- Clear reading: large, high-contrast values for short glances
- Focus Mode: show one key metric in a simplified full-screen view
- Haptic climb feedback: optional taps with adjustable sensitivity
- Altitude calibration: manual altitude, QNH and source labels for a clearer setup workflow
- Metric and imperial units
- Clear one-time purchase: no subscription model

Live flight metrics:

- Vario device battery status
- Altitude with source indicator
- Climb and sink rate
- Flight duration
- Ground speed, course and glide ratio where supported by the connected device and data stream

Altitude calibration:

Tracerlink 2.1 adds a more deliberate altitude setup workflow. Depending on your connected device and available data, the app can work with manual altitude calibration, QNH-based altitude or GNSS-assisted calibration where supported. A compact source label shows how the displayed altitude is currently derived.

Focus Mode:

Focus Mode gives one selected metric more space on screen, such as altitude or climb rate, for quick reading in the air.

Haptic feedback:

Optional haptic feedback can signal climb with subtle taps. Sensitivity can be adjusted in the watch settings.

Workout integration:

Tracerlink uses Workout mode to help keep the watch display active during flight and to track flight duration.

Compatibility and requirements:

- Devices: UltraBip, BlueBip or XC Tracer
- Apple Watch: watchOS version as listed in the App Store compatibility section
- iPhone/iPad app: includes manual and support information; flight data is shown on Apple Watch
- GPS-dependent values are available only when the connected device and data stream provide them
- Compatibility with older device models or outdated firmware is not guaranteed

### 5/5 — Perfekt für Hike and Fly

*2026-06-09*

Super Idee und gut umgesetzt! Genau das was ich seit Jahren suche. Nutze es mit einem XC Tracer mini II GPS und der Apple Watch Ultra. Ein Problem mit Bluetooth und dem Anzeige-Name (XCTracer und nicht XC-Tracer) wurde super schnell und mit Netter Kommunikation des Entwicklers gelöst! Danke Vojtech, mehr davon!!!

**Developer response:** Vielen Dank dir für die Bewertung! Freut mich, dass Tracerlink mit deinem Setup gut funktioniert. Genau für solche Hike-and-Fly-Setups wurde die App gemacht. Die Anpassung mit dem Bindestrich ist umgesetzt und wird im nächsten Update auch unterstützt. Schöne Flüge. Vojtech

### 3/5 — Need to support other units of measurement

*2025-07-07*

App looks good on first glance but it only works in metric units of measure.

The app needs to either pick current chosen units from XC Tracer on first connect or offer its own settings screen to provide the user to select their own preferences.

For info in US most of us use feet for altitude, mph for wind and ground speed and feets per minute for vario. Hope this can be added to the app. 

Thanks for considering

**Developer response:** Thanks for your feedback. Imperial units are already included in the upcoming version and will be available with the next update.

### 5/5 — 👍🏾

*2025-03-16, version 1.0.2*

Jednoduchá a funkční appka. Při lítání oužívám radši než telefon nebo jiná varia

### 5/5 — Konečne

*2025-02-26, version 1.0*

Na todle jsem čekal dlouho. Funguje skvěle. Díky:)
