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.
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.
Great App! Wish it had ALL U.S. coins including pre Barber Coins As a collector, this app makes it SO easy to keep up with what I have and what I need. I shop at flea markets, garage sales, etc, and it's like I always have my collection in my pocket. I just wish it had all the other U.S. coins. The way it is designed. If the other coins were available, they don't have to be used. That way the collectors who have no use for those lists don't have to see them. PLEASE PLEASE PLEASE add the other coins. I would definitely rate it 5 star then.
Love it! A couple of ideas... Great app for coin collection! Would love ability to edit collection names at any time. Also, please add 1982 penny varieties. Thank you for your awesome app!
F'n the Best! This app is the best! Wish it had a few extras though, such as a complete coin type set and paper currency too. Highly recommended for anyone who's new to collecting or anyone who's been collecting for years! App writer, get the redbook and use it to add in ALL the coin sets! allow for proofs too! This app could be the God app for us
- 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!
