Original review is below, but since writing it Ive got a couple of complaints that bring down my original star rating. 1) they CHARGE MONEY for email coin appraisals... I sent two in and never got a response. Their description says youll get a response in 24 hours, their automated email replay says within three days, I sent them in a week and a half ago and Ive heard nothing. 2) presidential dollars only go up to 2013. Where are the rest!? The series runs through 2016... 3) 1924 Lincoln wheat penny is missing from the list... Only 1924D and 1924S are in the system. 3) its becoming more and more apparent that I need this list to be exportable and/or sync between devices, Ive spent hours entering over $1,000 worth of coins and adding photos and values ect and youre telling me that when I upgrade my phone my list will be gone!? Thats BS... It seems like the developers have abandoned this app. ------------------------------ I bought a couple coin cataloging apps last night and I have to say so far, this is the best one. But I wouldnt say any of them are great... Ive only been playing with it one day but so far, Ive found myself wishing it did the following things: 1) Id like it to sync between devices. Sometimes Im on my phone, but sometimes Im on my iPad. 2) Id like the option to export my collection via email or excel. 3) Coins have two sides. I wish you could save 2 photos of a coin. One of the obverse and one of the reverse, or a close up of an error or type indicator, ect. 4) Id like those little arrows to disappear once you enter information into a field. They are annoying. 5) Id like a total of the amount paid for my coins as well as the total value of them, to know what my investments are worth vs what I paid. 6) remove the upgrade banner from the upper corner and replace it with one that says buy appraisals since thats what you really mean... Im sure Ill discover more things Id like in the app as I use it more but these are my suggestions so far.
