(Strategic Takeaway) {#so-what} All英語辞書 - English Dictionary is a reference app that is completely free. It holds a 5/5 rating from 1 review. > **Bottom Line:** Maintaining the current search index is the primary lever for retention, as the app's value rests entirely on the quality of its aggregated sources.
