I've been using Designrr for almost a year now, and it keeps getting better! It is my "go to" application when it comes to creating quick start guide, templates, eBooks and other content for my job and my business!
As a full time professor, I can go back into my archives of personal and professional publications, import them into Designrr and revise, repurpose, and reuse work without having to recreate it! In my side hustle, I can generate timely "how to" guides that take my professional look to the next level.
Don't get me wrong, I've tried a lot of other complicate ($$pricey) applications that over promise and under deliver, so for me Designrr is MY tool of choice. If this sounds like a 'too good to be true' pitch I recommend you try it yourself and see what I and others have found. It just works!
