Musical Meter 2 vs Dosis!

Musical Meter makes learning to read and play music rhythms fun. Thanks to its innovative, two-hand design, our app teaches you not only when to play a note but how long to hold it. Visual representations and animated examples let you see and hear how to play each music symbol. Interactive, randomly generated levels ensure you truly understand the subject matter. Our notation looks professionally engraved so you’ll be ready to read real sheet music. This precision app will hone your timing and help you develop a strong, internalized sense of rhythm. This second app in the Musical Meter suite introduces the following concepts: • compound time (6/8, 9/8, and 6/4) • eighth and sixteenth notes and rests • dotted quarter and eighth notes Sight reading and timing exercises are mentally demanding, so have fun but remember to pace yourself. Enjoy!

Dosis! makes everyday ionising radiation tangible – factual, multilingual and clutter-free. • Ambient dose: Shows the current dose rate of the nearest official monitoring station (Germany: BfS ODL-Info; Switzerland: NADAM/NAZ). Your location is used on-device only and never transmitted. • Flight dose: Estimates the effective dose of a flight from origin, destination, cruise altitude and travel month (solar cycle) – with intuitive comparisons (panoramic X-ray, days of natural radiation, hours on Guarapari beach, minutes in the Gastein radon gallery). • Food: Converts the radiation dose of 40+ foods into microsieverts and "banana equivalents" (potassium-40 and others). • Radiation hotspots: Places with extraordinary radiation – natural hotspots (Guarapari, Ramsar), nuclear sites (Chernobyl, Fukushima, Mayak), space (ISS, Moon, Mars) and historical uses (shoe-fitting fluoroscope, radium dials and more) – with dose values, maps, photos and sources. • Learn: short, accessible articles – What is background radiation? Doses in medicine (with a table from dental X-ray to CT), the story of the banana equivalent dose, why food is radioactive, mineral water and infants. • Works worldwide: outside Germany and Switzerland the app shows a clearly labelled physical estimate (per UNSCEAR) instead of a measurement. • Topographic maps with country borders and capitals – for your location, every flight route and every radiation hotspot. Note: Dosis! is for information and education. It is not an official dose assessment or alert level. Languages: German, English, French, Italian, Spanish, Chinese.
