The audio content is good but there are important areas the app needs to improve:-Enable background audio so that way when you switch apps or put your phone in lock mode, the audio continues playing (just as you would expect with any podcast or audio app.)-improve the contrast. Lime green background with white font is hard to read.-enable GPS so that way you can play audio that aligns with your location in the Villa-enable a playlist so that way you can play all of the audio back to back without having to intervene. Currently, you have to finish an audio clip, price back, then select a new audio clip to play. Unnecessary taps and user input.-they should have free Wi-Fi at the ticketing location so that way tourists with limited data plans do not have to use up their data plan to download the app.
