I wish the design and function was a consistent experience on both my iPhone and iPad. Accessing my lists takes way more time on my iPhone than on my iPad i.e. more taps to reach them.
Additionally, browsing products is much better on the iPad. Granted, there is more space. But, I have to say, I use my iPad to browse items because I prefer that experience. The iPhone is like way too cramped in todays deals and I have to tap all over the place just to see items and check on items Im watching. I only use my phone to check out.
When looking up vitamins or frequent use products, I could really use a filter to show just items eligible for subscribe and save.
Other than my preferences, the app experience in general is fine. But, if I didnt have an iPad, it would be a much different review.
