In analysis of human or animal behavior you often have to record diverse activities. For example in field studies of Human Factors, Ergonomics, Psychology or in Biology you have to observe activities like tasks, interactions, states, postures, positions, locations, motions or any other observational events. To documentate your observations you need to record or store them with a time stamp. Your objective is a list or table of the observed events with their related time stamp of occurrence or observation. Therefor you may use traditional time study Apps of key-stroke or pre-defined button recording. But very probably you will experience a set of problems:
- You can not design your own user interface of recording.
- Instead you have to use a restricted predefined set of buttons or icons.
- You can not adapt the user interface to the context and your mental representations.
- You have to declare and fix the meaning of your buttons before recording starts.
- Memorization or learning of the fix set of buttons limits your event categories.
- You can not easily change or adapt your interface during recording.

The FIT-System (Flexible Interface Technique) App is different because:

(1) It allows you to design a recording interface graphically or pictorially. In using or designing graphic symbols, text or simply by using photographs of the observation setting you can reach a better performance in recording in terms of faster reaction time, less erroneous input and the management of a much more higher amount of event categories.

(2) Using the FIT-System you not declare the meaning of your interface in advance. There is no such thing like first defining everything of your study and then realize during pilot observations to change and redefine it. Instead you can start event recording even with a blank screen as your interface. The signature or meaning of your input in the FIT-System is done afterwards. It is a kind of reverse notation where you can focus on the observational character of the data and not have to narrow your capacities because of enforced occupation with predefined operators of the App.

In a field study of human or animal behavior you will often be confronted with the need of a relatively fine grain of analysis. Thus managing more than 10 activities and 10 states or locations is often the use case. To solve this with traditional event recording Apps is problematic because of the given interface you have to accept. You will experience that most event recorders are quite a kitchen knife. While the FIT-System is more the versatile Swiss Army Knife tool.

The result of the FIT-System App is a table of event data, i.e. the name or signature of the event and the time stamp in a table form. It can export to spreadsheet software as Numbers or Excel, or as a comma separated file (CSV) for use in statistical packages as R or SPSS.

Your work with the FIT-System is supported by a iBook tutorial free of charge (see support link on this page). Additionally it provides you with recording examples and literature links. The FIT-System App is just a tool and free of in-App registrations or advertisements.

If you consider to test the FIT-System free of charge, you will find a trial version "FIT-Basic" on the App Store. The trial version provides all functionality but restricts the number of event categories to five.

Using the FIT-System you will stay "in touch" with the history of Apple Inc. as the FIT-System software derives from a first App written in the nineties for the touch screen of the "Apple Newton Message Pad" computer.
