From jan 7th 2019 we will start charging for our services. To begin through "Packages". Soon even with a subscription model in intervalls where the lowest fair will be $ 0,5 per colony.  Remaining free coins will be limited to 20, that is 2 analyses. This will also be the level of free gift to new users.
In the app you can buy as many analyses (scannings) you need.
1 scanning = 1 $ = 10 coins = analyses of max 30 images from a colony. Buy in the app with your credit card. There you can view your account and order more coins whenever you need.
