Dosis!
Read full descriptionHide full description
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.

Maxillofacial integrates the body of oral and maxillofacial surgery knowledge into a single application, comprising a surgical atlas, coding reference, scholarly search engine, and the specialty's first dedicated professional forum. ATLAS A growing compendium of OMS procedures, structured for efficient reference before, during, or after operative care — designed as a working clinical resource for surgeons REFERENCE Organized across Anatomy, Perioperative Care, Emergency Management, Pathology, and Didactics, supporting concept review, board preparation, and protocol verification at the point of care. SCHOLAR A clinical query interface accepting natural language and standard OMS terminology, returning synthesized, citation-backed responses cross-referenced against major bibliographic indexes and current specialty guidelines, ranked according to evidentiary quality, with each claim traceable to its primary source. Scholar is intended as an educational and research reference tool and does not substitute for independent clinical judgment; all guidance should be verified against primary sources prior to clinical application. CODING Specialty-specific lookup across CDT, CPT, and ICD-10, facilitating direct progression from diagnosis to procedure to billing code within a single interface — addressing the persistent overlap between medical and dental coding in OMS practice. FORUM The first dedicated professional community for oral and maxillofacial surgery, supporting case discussion, residency and fellowship inquiry, practice management dialogue, and international collegial exchange among residents, attendings, and program directors. Maxillofacial serves as a unified repository of specialty knowledge and professional community — for residents preparing for board examination, attendings managing clinical practice, and program directors advancing surgical education.

Verdict
The clearest difference is update cadence: Maxillofacial at every 3 days against Dosis!'s monthly. Maxillofacial also leads on device support (3 vs 1). On price, ads, in-app purchases and iOS requirement there is nothing between them.
