This is a Scam app, they take your money to fund a project that you genuinely want to help, then they cancel the funding even though they had endorsed that project and with very little explanation and proof for their reasoning as to why it was cancelled. If you don't ask for a remboursement in a very short window of time that they provide, your money is given away. Don't bother with this app, I don't understand how Google play allows this to be downloadable on their platform.
