Your voice builds a reef. Stimmriff turns speech training into a game. You read short texts aloud, the app listens and shows you right away how clearly you spoke, how fast – and how many filler words crept in. The clearer you speak, the clearer the water in your reef becomes, and the more sea creatures move in. WHAT YOU PRACTISE β€’ Clear pronunciation – word endings, consonants, clean transitions β€’ A calm pace – neither rushed nor dragging β€’ Fewer filler words – β€œum”, β€œuh” and β€œbasically” fade with practice β€’ Confident delivery – from a single sentence to a whole paragraph 100 LEVELS, FIVE REGIONS From the sunny coast through the coral reef and the seagrass forest down into the lightless abyss. Every region has its own texts, its own light and its own creatures. The demands grow with you: short sentences at first, whole paragraphs in the abyss. For the third star each level asks a little more – and the app tells you exactly what is still missing. PROGRESS YOU CAN PROVE Rising scores alone prove little, because the texts get harder. That is why there is the benchmark: the same fixed text, at fixed intervals, always measured the same way. This comparison shows you in black and white what has changed in clarity, pace and filler words. TARGETED PRACTICE The app remembers which sounds you find difficult – swallowed endings, hard consonants, long words – and puts together matching exercises. FOR KIDS: THE JUNIOR REEF A separate area with Klara the turtle: the snake eel glides through rings as long as a long β€œSsss” lasts. The motorboat dolphin races to the island on a rolled β€œBrrr”. The parrotfish turns colourful when words are spoken clearly. Plus its own speaking path with short sentences. No losing, no time pressure. FOR EVERY SCREEN Made for iPhone, iPad and iPhone Duo – outside and inside. With support for larger text, increased contrast and reduced motion. YOUR DATA STAYS WITH YOU That is rare for a speech app, so here it is plainly: Stimmriff sends nothing. Your voice is analysed entirely on your device. No recording is stored and none is transmitted. No account, no server, no ads, no tracking. The app even works in airplane mode. A FEW MINUTES A DAY An exercise takes less than a minute. A reminder at a time of your choice helps you keep going, and every day in a row brings more pearls for your reef. NOTE Stimmriff is a practice and entertainment app for speech training. It is not a medical device and is not intended to diagnose or treat speech, language or voice disorders. The junior area does not replace speech therapy. If you suspect a speech, language or voice disorder, please consult a doctor or speech therapist.
