What’s new
New in Forty5.
Everything we added to the app lately.
Updated October 23, 2026
Learning
“I don’t get it”
One tap explains an idea again in plain words, with an everyday picture. In Physics, Math AA and Math AI so far.
Highlights and animated diagrams
Formulas and key terms stand out like a highlighter, and diagrams build step by step.
Worked examples
Every Physics lesson and every maths lesson now has a worked example.
Coursework guide
An IA guide for every course: how it is marked, a step-by-step plan, common mistakes and a checklist. It never writes the work for you.
Road to 45
An estimated grade for each course and your Diploma total out of 45, updated as you learn.
Study plan to the exam
Set your exam date and the app spreads the lessons over the weeks before revision.
Daily study goal
Choose 5 to 30 minutes a day. Only active study counts, and reminders change from day to day.
Listening and languages
Natural voices on every device
Lessons and language questions are read by natural voices on iPhone, Android, Windows and the web. Lesson cards are read in your language.
Two-voice listening exams
Conversations in the style of Paper 2, with questions, an optional transcript and slow replay. Five in every Language B and ab initio course.
Dictation
Language courses: listen to words and short sentences, then type them.
Slow replay
In language courses, the turtle button plays a question again, slowly.
Lessons in French and German
Lesson explanations now come in French and German too.

Three quests a day, and a chest every fifth day you finish them all.

A short round of the questions you missed, for double XP.
