iOS app "Wireless Tag List" version 1.6.1 with crash bug fixed is processing for AppStore. Please allow 24 hours for it to show up in AppStore around the world. This version supports 4 inch screen iPhone5, multiple tag manager (tap on the tag manager name to switch), and also setting auto-ping interval differently for each tags (this feature is not yet available in the Web/Android app interface.) By setting different auto-ping interval for different tags, you can make battery last longer for some tags while collect temperature data at desired frequency from other tags.
We also submitted iOS app version 1.7 for review. This version will no longer support iOS 4.3 and below. iOS 5.0 or above is required. In exchange, it has smaller app size for faster loading time.
