Worst app it is obvious that medical needs are something that cannot be delayed or cancelled at the last minute after waiting for days. Very bad experience my insulin pen was not delivered to me even after waiting for 3 days. If the item not available they should have informed that before i would have got it from somewhere else now i have been without my insulin for 3 days and will have order again which will take 2 more days. Uninstalling the aap right away😡
