I bought this app and the EXPENSIVE MacBook app specifically so my computer and phone would be synced. NEVER works, and Ive had totally wimpy responses to support requests. One mentioned that I have a lot of cards--like your algorithm doesnt work regardless!?!? AND even when I deleted the iphone app completely and restored it via iCloud and then turned OFF iCloud sync, and took it travelling the iphone app failed to schedule my cards correctly. My advice--great app for phone only and only for a small number of cards.
