A really important element of WhatsApp's global success is that they had a Java ME app for featurephones.

US-centric competitors would only support iOS and Android, whereas WhatsApp was running on the hundreds of millions of 2003-2010 vintage Nokia/Samsung featurephones that were in daily use in India, Indonesia, Nigeria, etc.

That is also part of UX. When it comes to messaging apps, Snapchat is one extreme of the spectrum -- iPhone-focused, cryptic UI, teen-oriented, majority of users in USA -- and WhatsApp is the very opposite. Both are successful examples of UX focus.

> cryptic UI, teen-oriented

These things go hand-in-hand by the way. And that's not a complaint, it's just funny how "only teens bother to figure this out" can be an honest-to-goodness feature under specific circumstances. Especially if you (basically) need to be "introduced" to a program and all of its quirks through your friends.

I hated it at first, but I've come to really appreciate being able to swipe around through almost all the screens, vs. having to stretch across my phone to hit menus on the far corners in other apps

Agreed. They still need to put in more subtle cues to do things though. Most people don't know you can use multiple filters/stickers or touch a location to change it.
