RotoMe

RotoMe is a listening trainer for the oral interview in the Cyprus citizenship process. At the interview, questions are asked in Greek and by ear. Knowing the translation is not enough: you need to recognise the question when it is spoken quickly and worded differently from what you studied. That is what RotoMe trains. HOW IT WORKS You hear a question in Greek. You answer aloud. You open the translation if you need it. Then you move on. WHAT'S INSIDE - 311 questions across 23 topics - Several wordings of the same question, the way people actually ask - 98 key words with audio and translation - Three modes: shuffled, in order, by topic - Autoplay with an adjustable pause for your answer - Playback speed from 0.75× to 2× - Russian and English translations - Light and dark themes TOPICS Name and surname · origin · age · moving to Cyprus · work · income · family and marriage · children · parents · relatives and languages · free time · why you like Cyprus · home and address · Cypriot food · holidays and customs · religion · application and guarantors · education · passport · Cypriot friends · daily life · police · plans to stay FREE AND FULL ACCESS 46 questions — two from every topic — are free, so you can try all the sections. Full access unlocks all 311. One-time purchase, permanent, no subscription. WORKS OFFLINE Questions and audio are inside the app; no internet needed. The app collects no data. IMPORTANT RotoMe is an independent app. It is not affiliated with any government body of Cyprus and is not an official preparation resource. It does not guarantee that you will pass the interview and is not legal or immigration advice. Audio is generated using speech synthesis: an even pace and consistent pronunciation are useful for practice. At a real interview, speech may be faster and carry a local accent.

Verdict
The clearest difference is in-app purchases: RotoMe at none against Lambda Lingua's 2. RotoMe also leads on iOS requirement (15.0 vs 17.0). On price, ads and device support there is nothing between them.
