I am a night owl and yesterday night I read an e-book from Luke Wroblewski about the Polar app which I enjoyed very much: It’s very interesting, well written, explained in detail and completed with cute, heartwarming illustrations.
Short summary why this PDF is worth reading if usability concerns you (and even if you’re not in app developing):
- You’ll find thoughts on user interaction depending on the devices and different screen size (one thumb, both thumbs, mouse).
- When to register or sign in?
Recommondation: As late as possible, allowing users to interact and investigate. Store information locally prior to logging in.
- How to teach the app’s function?
Don’t let your users wait, they are eager to get started. Think of in time education instead of a longer guided tour at startup.
- How to display loading in progress?
You may have noticed on Facebook and the e-book explains in detail why they prefer a skeleton previews over a spinner.
- Force on your core strength and stick to your pattern!
The example is great and smart and I’m not gonna reveal it! Read it on page 32 ff.
