Great app for a novice coin collector. But there are GUI issues. For example, when you “grade” a coin (by taking its photo), and decide to “add it to a collection”, it doesn’t store the photo you just took. Instead, it stores a generic reference photo in your collection in addition to its Grade. If you want the actual photo (without the Grade), you have to use the different camera icon. When you manually add the value of the coin, the pop up window with the number-pad totally covers the rest of the screen & its difficult to close the number-pad (ie, no ‘cancel’, ‘close’ or ‘ok’ button). Overall, good app if you just want simple grading. In fact, I have several PCGS graded coins that CoinSnap gave the same grade too. Only real drawback on grading (which is very subjective), is that CoinSnap will only grade ranges, not specific values. For example, it will grade a coin as MS but not specifically MS63. This is a bit frustrating since MS runs from MS60-MS70.
