I was involved in prototyping, wire framing, reiterate and iteration of our iPhone and iPad app. A native app was created for iPhone and iPad originally with different style and feature set. As we received more challenges with load time, speed, and number of offers shown, a universal app was created to solve all those issues.
Some of the challenges were:
1. Ease for the Checkout process
2. Engage users by having related products and allowed ratings on wines purchased
3. Instead of showing max 12 products at a time, we wanted to show 200+. Loading time, cache, speed, were all taken into consideration.
