I am designing an app. I want to know store some metrics about my app in free cloud database. The metrics includes which functionality users using more, number of downloads, user preferences etc. Later, I would like to query this database to understand app metrics.
I googled and found there are some free database hosting services like FireBase, Buddy. I am not sure which one to choose for my use case. Any suggestions?
I know this is not a programming question but its a design requirement I want to make, and if it not the correct place to ask, atleast route me to correct path instead of simply closing or down voting.
