What is Forty5?

Forty5 is an independent study app for IB Diploma Programme students, with 54 IB courses (SL and HL separate) and over 1,700 five-minute lessons that follow the current subject guides.

Learn: every lesson teaches one idea with diagrams, tables, timelines and worked examples, drawn step by step like a whiteboard. Tap "I don't get it" to hear the same idea in plain words. Lessons are explained in 9 languages (English, Turkish, Spanish, French, German, Arabic, Russian, Hindi, Urdu), with questions in English as in the exam. Language courses add natural-voice pronunciation of key words, listening and dictation practice.

Practise: exam-style questions with an explanation after every answer, endless new Maths and Physics questions with worked solutions, IB-style papers, timed mock exams and a monthly mock. Reviews bring back what you got wrong, spaced out until the exam. Each course has a Notebook with notes by unit, formulas and key terms, plus a coursework (IA) guide.

AI Summary (Plus): upload your own class slides, notes, a worksheet or a photo (PDF, PowerPoint, Word or camera). Forty5 finds the course and gives you the lessons to study, a short summary in your language and 10 exam-style questions. Your files are never used to train AI.

Plan: set your exam date and a daily goal and Forty5 plans the weeks to the exam, with reminders, a grade estimate (Road to 45) and a home screen widget.

Play: XP, levels, daily streaks with streak goals and friend streaks, a character to dress with items from chests (earned only by studying, never sold for money), daily quests, monthly leagues, class leagues, a monthly tournament and duels with friends. Meet Fortie, the octopus.

Safe and free to start: no ads, no chat with strangers (friends by exact username), students under 16 stay out of public rankings, and parents can link a free account for a weekly report. The first unit of every course is free, no card needed. Plus unlocks every lesson.
