This can be used in a more limited way without subscription, and also has a subscription feature-, FYI, so be aware, but this is affordably priced and perfect for capturing behaviors- if you have a handful or two of students you need to track, you can use it without making in-app purchases. If you have more (It says the limit is 12 reports, so beyond that you will have to purchase an annual subscription. I got it back when it was non-subscription based, and the company did honor us old-timers by allowing access to the old app- which is very much appreciated. They also very clearly describe what is included in the description as well, so you can see if it is something that would be valuable to you. I appreciate and stand by companies who do this.
