## What is GyroMetrics?

9BMetrics connects to your Ninebot One, Kingsong, Gotway or InMotion and logs wheel information:

- Speed
- Current
- Voltage
- Power
- Pitch and Roll (only in Ninebot)
etc.

and combines it with the altitude change from the iPhone barometer and the GPS data.

Please be aware aware that continued use of GPS running in the background can dramatically decrease battery life.

Also if blocking lock screen is enable battery life will be shorter.

Each log may be analyzed graphically or exported in a ZIP file that includes a CSV file for each variable and a .gpx file for the GPS data.

A special mode allows to debug connection information between the wheel and the original Ninebot application (or other).

Another one simulates a real Ninebot One wheel so you may test applications with out the wheel.

An Apple Watch module allows to control your speed, remaining battery and km, distance and time simply from your watch while your phone is secure in your barg or pocket.

## Key features

- Logs speed, current, voltage, and power
- Integrates GPS and altitude data
- Graphical analysis of ride data
- Export data to CSV and GPX formats
- Diagnostic connection mode
- Simulates unicycle for app testing
- Apple Watch module for remote monitoring

### 4/5 — Bonne apps

*2020-02-01*

Très bonne application !!! Dommage qu’elle ne soit plus développée ni mise a jour. 
C’est pourtant une très bonne base qui demande qu’à être peaufinée.

### 3/5 — Wheel support

*2019-05-30, version 3.2*

Where is no ninebot z10 support?

### 1/5 — Ninebot One Z10 ??

*2019-01-29*

Hello ! Good app with my Ninebot One S2, but doesn't work with my Z10. The wheel connects but numbers stays to zero... 😕 

Bonjour ! Super app avec ma Ninebot One S2, mais ne fonctionne pas avec ma Z10. La roue se connecte mais les chiffres restent à zéro... 😕

### 5/5 — Cool app!

*2018-07-21, version 3.2*

Works great with my Gotway wheel. Love the track display.

### 4/5 — Super appli / Attention au signe sur 16S / 16B FW 1.27

*2018-06-07*

Une des meilleures applications de monitoring de roue !
Attention, depuis le FW 1.27 de la KS 16B, le courant est signé avec le bit de poids fort : l’application ne fonctionne plus hors retravail des CSV à froid, d’où une étoile en moins.
Mais grand bravo !

### 5/5 — Parfait

*2018-04-02*

Parfaitement compatible avec ma Rockwheel gt16
Pour moi cette appli à complètement remplacé celle du constructeur moins pratique et moins complète 

Appairage fonctionne bien en démarrant la roue en premier puis en démarrant l’appli en second.

### 5/5 — Super app !

*2017-12-31*

Application testée sur Gotway MCM4 et Inmotion V8. Fonctionne à merveille, sur l’Apple Watch aussi. A recommander !!

### 3/5 — Plantage

*2017-12-09*

Plantage sur la maps au niveau du bouton bleu à droite iPhone 6plus

### 5/5 — It does what it's take

*2017-04-09, version 3.1*

I have been looking for a kind of app like this that allows you to measure the metrics of you single wheel ride, regardless what equipment you have. The fact that the developer made it open source is an extra point in my book. Don't expect a nice UI, but expect functionality and you won't be disappointed.

### 3/5 — this app is suitable for any model EUC Gotway?

*2016-12-03*

I have Gotway mcm3. 9BMetrics sees it, but the parameters are not read.
