The skillset of design is a weakness from our team, we found fantastic and free handwritten fonts to use, but how can we draw the little arrow to the feature? How does that dark screen come up in onboarding design ( with the app underneath) is there an app for this that I can design the screen shots for our developer for our onboarding storyboards? Help? Bootstrapping!
This is quite simple with screenshots and Photoshop. If you are bootstrapping, try resources like fivrr.com, elance.com, or odesk.com
Otherwise, ask your friends/family/neighbors if they have a copy of Photoshop for you to do this.
If you'd like, setup a call and I can have my in-house designer do it for you.
