Solution for storage virtual coins in mobile application
<p>What is the best solution for storage of virtual coins in a mobile app?
Of course I can store locally on the device only, but this has many disadvantages I think.</p>

<p>For online solutions, how do you handle synching the coins when there is no connectivity?</p>

<p>Are there some services who do these things, or should I write my own service?</p>
