Toki

Toki is a live voice interpreter that works where the internet doesn't. On planes, in cities without roaming, at field interviews and overseas meetings. Toki understands you as you speak and interprets on the spot. Speech recognition and translation both run on your iPhone, so you need neither Wi-Fi nor roaming. LIVE, BEFORE YOU FINISH Words appear while you're still speaking, with the translation flowing right underneath. When a sentence ends, its translation moves up large and stays there long enough to read. However fast the talk gets, you read one sentence at a time. FLOATING OVER OTHER APPS Send the translation to a small window and it stays on screen while you watch a video or check a map. Short vertical clips are no different, foreign speech reads as it plays. The window's play button pauses and resumes interpreting. 100% ON-DEVICE, NO INTERNET Download the language packs once and Toki keeps working in airplane mode. Losing signal never stops the conversation. 9 LANGUAGES, ANY PAIRING English, Korean, Japanese, Chinese (Simplified), Spanish, French, German, Italian and Portuguese, in any combination. SAVED AUTOMATICALLY Slide to finish and the whole conversation is saved to History. Expand, copy and share it anytime. PRIVATE BY DESIGN No servers, no accounts, no ads, no tracking. Audio is discarded right after recognition and never stored. YOUR INTERPRETER BUDDY Toki is a slightly spaced-out baby bunny. It listens closely with its long ears, interprets, and dozes off when you pause. Poke it and it hops for joy, with a soft boing on every bounce. FIRST 30 MINUTES FREE Every feature is fully open for your first 30 minutes. To keep going, subscribe to Toki Pro for unlimited translation time.

Verdict
The clearest difference is update cadence: Toki at every 2 days against Underlairs's every 3 weeks. Underlairs's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 26.0). On price, ads and in-app purchases there is nothing between them.
