This is a great stand-alone app. When I moved my exported files into my new Galaxy S7, I couldn't import without an error. As it turns out, the app needs to be given permission to read/write to the memory. For android 6, the apps have to ask...the permission isn't granted at the time of download. I don't remember it asking. But when I opened my app manager and looked at the details, the permission wasn't granted. I turned on that permission and bingo, I could import my collections and be all set on the new phone. Thanks for a very straight-forward, helpful app.
Need major work for the collector I collect older more rare coins. Such as: 1911 5 Cent Piece/ 1865 2 Cent Piece/ 1790 NY Colonial Penny/1838 NY Colonial Penny... None of these coins in the app go to the older coins.
War Coins Missing Good app but it would be nice to see steel penny images for 1943 and the Nickel collection is very inaccurate for 1942-1945; no P mint marks and it is missing a 1942 coin because of this (there was a no mint mark and P mint mark coin that year from Philadelphia). A less annoying set of missing coins are the 7 different 1982 pennies.
Coin collection Allows easy inventory on all of my sets . I would like to have it combined with Dansco and Whitman albums for Easier input, I am awful with computers but I did fine with this app ! Thanks very nice appearance as well. Just imagine an app that combines (Dansco,Whitman,PCGS, NGC,ANAC and the RED BOOK of US COINS) all in one ! That would be "THE BOMB"! TOTALLY AWESOME
Good but missing coins Missing Blue Ridge Parkway Quarter. I also had a problem importing my collection when moving to a new phone, it would be good if it could say that it didn't have access to the filesystem.
Like the app idea.. This is a good app and a great idea. However, I was disappointed to see that I couldn't add the proof and silver proof coins to my washington quarters collection. Sometimes those are the ones that I need. Perhaps you could add those.
- 2016 coins have been added
- Collections can now be reordered
- bug fix - Jefferson Nickel collections now start at the correct year  (existing collections haven't been changed, though.)
- bug fix - Import/Export won't break if you have a '/' in a collection name
- several other minor bug fixes
Thanks to everyone that has rated the app, left feedback, and emailed me suggestions. It's awesome to hear what you guys think of the app!
