First and foremost, the team are extremely communicative and helpful. Every question we asked was answered in minutes and they gave us fantastic and friendly assistance to get us onboarded swiftly. 100% awesome.
The QA feature found literally thousands of errors throughout our translations — we had missed these for *years* using our previous tool.
We export our translations for use in an iOS and Android app — there are variable placeholders in several files and Lokalise makes it super simple to define these so they are exported to the correct format for the target platform; no need to write scripts to convert from iOS "%@" to Android "%s" etc...
Additionally, we love the platform-specific features; being able to specifically disable a key for export on iOS or Android, or change the name of the key when exported, so that it can match that platform's conventions.
The pricing model is sensible, you are charged on translation keys and not penalised for adding new languages. Again, this is way better than other solutions on the market.
When importing translations, Lokalise is intelligent and recognises the language.
All the modern (and obscure) localisation formats that we needed were available.
The web interface is intuitive and easy to learn, you can tab across navigate quickly.
