After selecting a target language, tap "Translate text" and watch your message get translated right in the app! If you'd like to translate a message you received, tap and hold it until an option to "Copy" appears. In TransKey tap "Translate copy", and the translation will appear in the same place!

The clearest difference is ads: TransKey at none against Dialog's shown. Dialog's advantage is chart position (#110 vs unranked) and device support (4 vs 2). On price, rating, review sentiment and ratings volume there is nothing between them.
