Thank you for asking. The Thinkfinity app has been fixed and both iOS and the Android versions will be available very soon. The iOS version is currently going through the Apple process to get it available on iTunes. As soo as it is available I will make an announcement in the Help Center.
Note: When the revised Thinkfinity app becomes available, you may download it and you will not have to change your login information.
Thank you for your patience.
Jane, Thinkfinity Community Manager
As a follow-up to Jane's reply, here is the link for the Android Thinkfinity app in case you and others are searching Google Play to locate the app--https://play.google.com/store/search?q=Thinkfinity+App
Hope you were successful in getting this app to work. I have used the app on my Smartphone and it works fine!
