Open R-Speedo · Last verified: 2026-08-15 · Current app version: 1.0.47
- Shows speed, battery, controller, trip, navigation, and charging-session information across ten dashboard layouts.
- Reads supported Votol, Fardriver, and VESC controller telemetry, plus Gesits and an experimental unofficial Polytron module path.
- Reads supported JK, Daly, ANT, and JBD battery management systems over Bluetooth.
- Can synchronize time and mirror Layout 6 navigation to a supported Alva Cervo BL-CERVO head unit.
- Supports BLE TPMS sensors for front/rear pressure, temperature, battery/freshness, and warnings when available.
- Works in GPS-only mode when no compatible Bluetooth hardware is available.
- Provides route planning, charging-station and workshop context, trip reports, exportable ride data, and optional live-rider sharing.
- Supports multiple configured battery packs with per-pack visibility and guarded aggregate telemetry.
- Includes Layout 7 for motovlog recording/snapshots and Layout 8 Dragger for GPS-based performance timing, evidence, ghost/rival runs, and leaderboards.
- Includes Layout 9 road Dyno for local paired-pull analysis and Layout 10 Canvas for custom telemetry dashboards.
- Provides an Indonesia-only hardware Shop with product details and WhatsApp handoff.
- Runs as a web/PWA app and as an Android APK with native Bluetooth, background recording, file handling, offline licensing, start-on-boot, and a home-screen telemetry widget.
Public screenshots and video are planned but are not published yet. When added, they will use synthetic demo data and safe public locations.

An integrated brand or protocol is not a guarantee that every model, firmware version, clone, or third-party Bluetooth adapter will work. See the compatibility notes before choosing hardware.
- Web/PWA Bluetooth requires a browser and operating system that implement Web Bluetooth.
- Safari on iPhone/iPad does not provide native Web Bluetooth support; GPS-only use still works where normal web/location APIs work.
- Bluefy or other WebBLE browsers on iPhone are user-tested workarounds, not the same as native iOS support.
- A native iOS test/sideload target exists, but there is no public native iOS release.
- GPS-only mode cannot provide controller, cell, fault, current, or other hardware telemetry.
- Layout 8 Dragger is a GPS/performance mode with evidence and quality gates; it is not official race timing equipment.
- Layout 9 road Dyno produces practical estimates from road and telemetry data; it is not a chassis dynamometer.
- Mobile operating systems may suspend browser activity in the background; the Android APK provides additional native background support.
- Charging-station and workshop community data can be incomplete or outdated.
- Polytron integration requires an external unofficial module and does not support writing controller settings.
- R-Speedo is a monitoring aid, not a replacement for manufacturer limits, calibrated instruments, or safe riding practices.
