2.99 doesn't hit my sweet-spot. And I realised that the price has stopped me from investigating the app further, to see what premium features it may offer.
The sweet-spot to get me to check the app specs would be 0.59. Having now watched the video, I'd assume that you would get a referral fee from GoDaddy, at which point I'd want the app for 0.00.
Thanks for the feedback guys. I've thought a lot about this and have some experience building domain tools. The truth is nobody ever purchases domains through the app.
You need massive volume (like advertising) to make this model work--it's just not there.
Making the app paid lets me keep the service running for the few people who think it's valuable enough to pay for.
This is a better solution I think than shutting down the service all together.
I'm definitely considering an ad-supported or free version, but wanted to start with a paid version first.
