It is a great beginning for us because it means that our app is both useful and working like a charm.
In a few days we demonstrated that we were able to help three users to earn $1,000 thanks to Flexomatic and Amazon Flex.
When a user subscribe, they can use 20 free "blocks" (as we may call "credits") to use the app for free. The free plan lets them use 5 free blocks a month.
We do hope that we will reach our first payment soon for users to buy extra blocks in case they regularly use our app!
