MyÆDN
Read full descriptionHide full description
The app is in French. MyÆDN is a revision planner for French medical students in their second cycle (DFASM) preparing the EDN, the national written exams of the second cycle. SUBSCRIPTION REQUIRED MyÆDN is a subscription app: planning, calendar, final-review mode and sync require an auto-renewable subscription, after a 7-day free trial. Terms at the end of this description. THE J METHOD, AUTOMATED You remember better when you review an item at growing intervals (J0, J1, J3, J7…). MyÆDN works out when to review each item of the official list and shows only what is due today. A PLAN THAT FITS YOUR LIFE - Enter your year, your EDN date, your working days, your hours and your breaks. - Add placements, holidays and days off: the app moves reviews to your next available days. - Something came up? Change today's hours only, with a preview before you confirm. - Split a large item, add your own courses, restart a whole subject at J0 over one to three weeks. YOUR DAY, YOUR WAY - Hours for each day in several slots; "Mes horaires de ce jour" changes one day or a period (placement, shift…). - Habits and markers (meals, bedtime), the order of your day (J0 first, reviews first or by priority) and a 24 h view. - Ancrages (your error deck) placed when you want; a pass can be done as MCQs only. - Subject blocks: time reserved for one subject (collège) each week, filled with its due passes. - Your calendars in a second column of the day view: say once per event whether it gets in the way. - Item list with last seen and results; "Ma passe du… était la J…" turns an earlier pass into your J3; split items and merge them back. - A clearer home screen: one Add button, and how far behind you are, without red. A VISUAL CALENDAR See your workload over several weeks, coloured from light to dense. Tap a day for its detail. Track your coverage: items seen, in progress, mastered, by subject and overall. FINAL-REVIEW MODE As the EDN approaches, switch to final review: the app spreads read-through passes over all your items and shows an honest summary when time runs short. iPHONE + iPAD SYNC Sign in with your e-mail and find your progress on iPhone and iPad. STAY REGULAR Evening check to postpone or validate what was not done, streak of consecutive days, morning and evening reminders, quote of the day. ACCOUNT PROVIDED BY A PREP SCHOOL If a prep school gave you your account, it only sees that the account exists and the date you last used it: nothing of your work. SUBSCRIPTION A 7-day free trial is offered, then the auto-renewable "Calendrier" subscription unlocks every feature: monthly, every six months, yearly, or yearly "until the EDN". The price for your country is shown in the app before you confirm. Payment is charged to your Apple Account at the end of the free trial (at purchase if there is no trial), then at each renewal. The subscription renews automatically unless it is turned off at least 24 hours before the end of the current period. You can manage or cancel it at any time in your App Store account settings. Any unused portion of a free trial is forfeited when you buy a subscription. Terms of Use (Apple EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Terms and conditions (French): https://pacedstudy.fr/myaedn/cgv Privacy policy (French): https://pacedstudy.fr/myaedn/confidentialite AN ORGANISATION TOOL, NOT A MEDICAL DEVICE MyÆDN helps you organise and plan your revision. It is not a medical device, a care tool or a source of medical content: it provides no course and no clinical advice, and processes no patient health data. MyÆDN guarantees no result, ranking or success at the EDN: your progress depends on your own work.
