I love everything about InVision.
Since I started using it 3-4 years ago they improved so many things and added really useful features. They collaborate with so many top designers of the industry that they always know what we want. I really appreciate the effort, time and love they put into their products and it's always fun to use them.
The tools I use on a weekly basis are:
InVision (Webapp); Freehand; Craft; Designbetter.co
All my designers loves the service, but I am struggling to use it, I find its UI/UX uncomfortable and not obvious. The most terrible is a mobile version of the web-site, extremely slow.
- Atomic has exactly what you're looking for. I use Components to break down prototypes into smaller chunks (think Symbols in Sketch). Then I can have anyone on my team work on a component and pull it all together in a prototype. As you build a bigger library of components, prototyping your product will get faster. This comes in handy when you have little time to create prototypes (e.g., design sprints). Check Atomic out and let me know what you think!
