It’s a bit early in the month to say that conversions are down, in my opinion.
But here’s my stats from the start of July up until now for comparision, if it helps:
Downloads: 296
Sign Ups: 141
Depositors: 19
My own rule of thumb is that if I’m getting 1 depositor in 7 sign ups, then I’m doing OK, so things look steady from where I am.
