Most people don’t think about keystrokes when they register a domain. A great tool to check the mobile keystroke compability is Domainatron. Domainatron checks domains for their mobile usability.
I guess Viooli.com is pretty bad:
| Keystrokes: | 24 |
| Modes: | 1 |
| Repeat Keys: | 1 |
| Obscure Keys: | 1 |
