I’ve put a lot of work into making the trntxt experience as efficient as possible. Even though it was designed for old phones with a slow connection, it works well on modern smartphones, and in my opinion, beats any train times app out there. Of course I think it’s better (I did make it after all), but I’m going to try and explain why it’s better.
I once learned that when someone looks for information, it is best to have that information displayed after as few gestures as possible. My experiment compares the use of the National Rail Enquiries (NRE) app with trntxt, on both initial setup and subsequent use. I’m going to dig out my old iPod Touch for this because my phone doesn’t do screenshots and nobody else has Windows Phone 7. At the start of the experiment, we are going to assume that you know the name of the app but it isn’t installed, and you know the URL of trntxt but have never visited it before.
