I like that it's easy to install apps with multiple languages available at once (also very cheap).
It also has an inbuilt translation system so you don't have too worry about any language barrier between your user base/customers! The UI could be better but this can probably be improved by adding more features over time as well if needed - which they will do eventually right? There are other competitors out there who offer similar services however DYIPP does them all much cheaper than theirβ¦
Pros
Easy, intuitive interface
Very responsive support team
Ability for multi language usage within same app is good.
