One of my favorite combinations is Sketch + Invision.
I develop the prototype with Sketch (sketchapp.com) then I import the prorotype to Invision (invisionapp.com), make it interactive/clickable, and share with all my testers to gather feedback/comments.
Let me know if you have further questions - I'd love to help!
