Not really free

I tested this app by uploading a picture of a plant I already had identified. I had to use (or get?) a coin before I even knew whether they had correctly identified the plant. They did correctly i identify it. But I dont like the pay aspect or the wait to get in and then if Acacian. On the plus side, another app I tried that did picture comparison was unsuccessful

Stupid nickname requirement about FlowerChecker, plant identify
