Improv Tonight is an app I created to scratch my own itch. I am very active in the local improv theatre scene in Chicago, but found it was very difficult to quickly see what shows were playing around town. The old method involved having to visit each theatre's website to get the showtimes, most of which did not play nicely with mobile.
With Improv Tonight, one can quickly see all the shows playing around Chicago in the same amount of time it would take to just load the theatre's website. In the first week of launching, the app was downloaded over 500 times for both iOS and Android.
