We made a high fidelity wireframe to test the idea, content and user flow. We did that for each part of the app.
We also made an interaction wireframe to test the usability in the early stage before starting UI design.
" We made over 240 pages of wireframes for whole project "
After validating the idea and usability using wireframe and interaction prototype, we designed the app with pixel perfect user interface.
We also designed and built the landing page with the same style and consistency for the whole product.
