Touristic APP - from low to high fidelity

What was my design specifications ?

The client wanted an app where I can booked hotel and show places for a touristic target audience. On the model of booking.com , the app is using google api to get to the booking. The wanted to build an app per city. The app is available on the appstore – Civitatis Dublin

I used Sketch (+ Invision for prototyping and Zeplin plugins for Integration) , Principle (motion prototyping) , Balsamiq ( for wireframing) and others Adobe creative cloud product. The system was quite complex (see workflow) so we has still to show lot of information.

The app took 6 months to be developp with many wireframes reviews 

 Finally send to the dev team ?

Using sketch and Zeplin to export and make the final version
