Meteor is an indie, third-party* app for use with the EEVBlog 121GW Bluetooth-LE multimeter. It performs most of the same functions as the EEVBlog app, but adds some new features:

+ Control buttons available in landscape mode
+ Option for spoken measurements (using iOS voice synthesizer)
+ Option for continuity buzzer
+ Dark mode option
+ Connect/disconnect button and disconnect-status labels

There are, however, a couple of features missing from the EEVBlog app:

- Does not yet support multiple meters or math mode
- No in-app capture of samples

This is a public beta, designed to get as much feedback and testing from 121GW users as possible. While I believe any public version is as bug-free as possible, please be aware that this is beta software and should not be relied on for critical uses until actual v1.0 release.

At app startup, you should see a page listing any 121GWs that are advertising near you. Or, at any time you can tap and hold the meter icon at the bottom-left of the main screen to bring up the meter-scan page. (This page is also available from the app menu, which you access through the button at the bottom-right of the main screen.)

The meter icon at the bottom-left of the screen should turn blue when you are connected to a meter. If you don't get any readings from the meter, please try tapping the meter button once to disconnect, and then again to reconnect.

* Love it or hate it, Meteor was not produced, endorsed, or licensed by EEVBlog. Please do not contact EEVBlog for support - instead email with any bugs, help requests, and feature suggestions. Thanks!
