The app has a nice interface, is stable and works well, but ultimately - as has been pointed out several times by other users in previous reviews - it is too expensive for what it offers. The author insists on making price comparisons with 'DeployBot' - one of many online continuous-deployment services targeted at workgroups with multiple live sites. This is, of course, only one of many. Some of the others include FTPloy (mentioned previously), DeployHQ, and Bamboo. All of these charge monthly fees, but offer many features that go beyond this package - e.g., ability to deploy from SVN or Mercury, as well as git.
The fact is, that if you are a developer using git, you are not afraid of complex tools, and is likely to have at least a passing familiarity with the command-line. If you are managing multiple projects on services like GitHub or GitLab, you'll know that these services also offer tools that you can use to setup your own automated integration-and-deployment scripts - and there is a wealth of materials online to show even the greenest newbie how to do that.
But you don't even have to invest that much time or effort into your automated deployment. If you don't want to go and learn how to write GitLab CI/CD configuration files, then just use a tool like git-ftp, suggested previously. That is a free, open-source tool that is pretty powerful, and requires no configuration at all - you just have to learn the single-line syntax command to use when you want to update your site.
I give this 3 stars, for the work that the author has put into developing the nice interface, making the app stable and performing its limited functions sufficiently well. There is definitely something to be said about an easy-to-use interface. But I deduct 2 stars due to the limited functionality, and the pricing - which the author stubbornly insists on keeping, despite user feedback.
