Our current workflow in Lokalise: when a copywriter populates all 3 languages, we trigger a CI pipeline, which exports iOS and Android localization bundles and integrates them into our application repositories. We use a separate github public repo to push/version all localization files. Pretty simple.
Lokalise has a very user-friendly interface, the filters and tags are extremely helpful in keeping everything organized and the in-line editor which synchs in both directions is a very neat little tool. Even just being able to attach screenshots to provide context has been a huge timesaver. Overall, Lokalise does exactly what it's supposed to do and the constant development has improved the software already so much over the time I've been working with it. However, the most noteworthy thing is the outstanding customer support that deals with questions and issues in record time.
