PoliLingo turns your iPhone into a real-time voice translator. Tap a microphone, speak naturally, and hear what you said in another language a moment later. Tap the other mic when they reply, and PoliLingo translates back. Two halves of the screen, two languages, one conversation. PoliLingo runs entirely on your device. The first time you pair two languages, iOS downloads the language pack — after that, no internet connection is needed. Your audio is never uploaded, never recorded to a server, never shared with anyone. — TRANSLATE BETWEEN 9 LANGUAGES — • English • Spanish • French • German • Italian • Portuguese • Japanese • Chinese (Simplified) • Russian — BUILT FOR REAL CONVERSATIONS — • Big push-to-talk mics — one per language, never tap-and-hold • See what you said and what was translated, side by side • Hear the translation read aloud in the target language • Swap languages with a single tap • Conversation history stays on your device; swipe to delete — PRIVACY-FIRST — • 100% on-device speech recognition (Apple Speech framework) • 100% on-device translation (Apple Translation framework) • 100% on-device text-to-speech (Apple AVSpeech) • No account, no analytics, no third-party SDKs, no ads — PERFECT FOR — • Travelers ordering food, asking for directions, checking in to hotels • Multilingual families talking to in-laws or grandparents • Quick conversations with neighbors, drivers, customer-service staff • Anyone learning a language who wants to compare what they said to a reference translation PoliLingo is free, with no in-app purchases. We hope you carry it everywhere.

Verdict
The clearest difference is ads: PoliLingo at none against Calculator⁻'s shown. Calculator⁻'s advantage is device support (3 vs 1) and iOS requirement (13.0 vs 18.0). On price and in-app purchases there is nothing between them.
