Mobile prototyping from the past.
Why should I use this?
You shouldn't. You should use a modern prototyping tool if that's available to you. These are great options: Framer, Principle, ProtoPie, and Origami.
What's Lemonade for then?
There are niche scenarios in the industry that hand you lemons:
- Companies don't have licenses of prototyping tools.
- Prototyping tools are not IT approved.
- Prototyping tools are available, but the online-sharing portion is not approved to use.
- The work is so secretive that it cannot be uploaded to vendors' servers.
First, try everything else.
And then, if you're still curious, give this one a try.
