I have the android weather station app working fine on ruuvi tag.
I understand you are about to bring out iOS version soon.
Perhaps on this version, you could improve the alerts in terms of adding vibration alert option as well as longer/stronger alert tones. If you use tag for say lost luggage, then vibration alert is essential. Also, in android if you get one notification on screen, then further notifications are silent until you clear all other tag notifications. It would be great to improve alerts as above in new iOS app ?
Also, can you use commercial bluetooth gateway with wifi to connect to say Streamr service and do you recommend one suitable ? Can the phone be used as gateway to Streamr service ?
