Just launched Pinegrow Web Designer ( http://pinegrow.com ) two months ago. The company is actually run by my wife and me, but I do all the work with Pinegrow while she is taking care of our other projects. Pinegrow has been paying most of our bills since launch and I have a lot of expansions in the pipeline: full support for Foundation alongside Bootstrap, developer edition that'll work with templates, a similar app…
Man, 3 days is nothing! Give me some time to fall in love, and I'll happily pay. It seems so shortsighted, as if I'd somehow use up all the usefulness of your app in 7 days or perhaps even 30 days. Its a tool for work, and if it can reduce my load in any significant way I'd pay $500 for it. Now, I'll never really know. Too bad... for both of us.
I get your point and have thought a lot about it before deciding on 3 days.
3 days was a compromise between having a short sales cycle (we are bootstraping the app) and letting users try the app before they buy it. We also have an online version available for free without any time limitations. The only thing the online version can't do is open local files.
We'll reconsider extending the trial to 7 days.
If you like the app and feel it could be useful to you it would be a shame to blow it off simply because of the short trial. If you need to try it out for longer, just send me an email and I'll set you up.
