NEXO: Daily Medical Diagnosis
Medical
NEXO is a daily clinical diagnosis game for physicians and medical students. Every day a new fictional case is published with up to 6 progressive clues. You search for the ICD-10 diagnosis and get proximity feedback in 5 levels: exact code, same category, same group, same chapter, or different chapter. A wrong answer tells you how close you were, so the error itself teaches.
Beyond the daily case there are two other modes. Continents brings 103 cases organized by regional epidemiology across Africa, the Americas, Asia, Europe and Oceania. Multimedia brings 123 cases built on real clinical images and sounds: X-ray, CT, MRI, ultrasound, ECG, endoscopy, colonoscopy, dermoscopy, fundoscopy, physical exam, histopathology, blood smear, karyotype, PET/CT, otoscopy, mammography, colposcopy and cardiac and respiratory auscultation.
649 cases across 25 medical specialties, in 6 languages: Portuguese, English, Spanish, French, German and Russian. Global leaderboard, achievements and daily streaks. The daily case is free forever, with no ads.
NEXO is not a clinical diagnostic tool. It is an educational game based on fictional cases, for training purposes only.

Unscript: Speak English Daily
English speaking
Unscript is an English speaking practice app for iPhone, built for learners who know the words but hesitate when it is time to speak. Practise the same real-life conversation through four levels: read the full line, fill missing words, use first-letter hints, then speak from the meaning alone.
Word-by-word scoring shows what you missed. Replay your own voice beside a model reading, look up words in the built-in glossary, and revisit conversations with spaced repetition. Speech recognition runs on your iPhone; recordings stay on the device for the current practice session. No account or ads are required, and optional progress sync uses your own iCloud.
The library covers 562 dialogues across 61 situations. The free tier includes 44 dialogues and all four practice levels. Unscript Pro unlocks the full library through a subscription or a one-time lifetime purchase. Available in English and Simplified Chinese on iPhone with iOS 17 or later.
