1. Device Compatibility
Lumu lite basically still works with iPhone 7/7+ and lightning to 3.5mm adapter, but we don’t recommend using it. There is a glitch in iOS that makes Lumu connect and reconnect every 10 seconds or so, when used in combination with Lightning to 3.5mm jack adapter, making Lumu unusable on devices without a headphone port.
The Lumu Power works on all iOS devices from iOS 8+ / all iOS devices that have Lightning connector port.
2. App Compatibility
Currently the only app working with Lumu Power is our own free Lumu Light Meter app: https://itunes.apple.com/us/app/lumu-light-meter/id730969737?mt=8
We have plans for making a public SDK for Lumu Power but ETA is currently unknown. Lumu Power SDK is currently being developed. If you're interested in working with us, please take a quick survey so we can get to know you better.
2.1. Pinhole app
There's already a pinhole mode in the current Lumu Light Meter app available to download at: http://appsto.re/i6d85B3
After you've installed it on your iOS device, just tap 'PHOTO AMBIENT' on the home screen. Tap the PHOTO SINGLE label at the top of the screen and select PINHOLE to enter the PINHOLE mode. You will need to have Lumu Power plugged in to be able to access this mode.
Snapcount only works with first generation Lumus, which are not available at our store anymore. Lumu Power, available at our website, is currently not compatible with Snapcount's software.
