The iOS version of the RangeTech app is done, we are just developing the necessary hardware at this time. We have working prototypes and are close to bringing them to production.
This is a good opportunity to note that the iOS version will have to be a bit more expensive than the Android version. You can thank Apple for that, as, in their infinite wisdom, they prohibit apps from dictating what speaker they use. This means that the RangeTech hardware for iOS will have to have its own speaker.
