Train skills you'll need during case interviews with exercises that fit in your pocket and can be done on the go. Caser is a fast and focused case interview trainer built for key ingredients to success: the structure you're approaching the case with, coming up with creative, well-structured ideas during a brainstorm, and answering personal fit questions the right way. Use flashcard-style practice for structuring and brainstorming, the two well-trainable sub-skills in consulting-style case interviews, done in short reps instead of long-form mock cases. If you're prepping for management consulting interviews, sharpening your strategic thinking through ambiguous business problems, or just want your frameworks to stop feeling generic, Caser turns casebook practice into active recall - just like training your muscles during a workout. Read the prompt, think it through, reveal the model answer, and rate yourself. When you do it enough times, MECE becomes how you naturally break problems apart. You can customize a session by difficulty, case type, or leave it open and let Caser pull from your full library. Work Caser's drills across: - Structuring exercises, where you read a case prompt and reveal a model issue tree: a clean, MECE hierarchy of branches and sub-branches, with coaching notes on why it's shaped the way it is - Brainstorm exercises, in which you read an open-ended prompt and reveal the expected idea buckets with examples - Personal Fit questions, where you'll be shown an interview question and then given guidance for improvement For Structuring and Brainstorm modes, choose the practice mode that fits your moment: - Reveal & Rate for fast, flashcard-style training - Build It for deeper practice where you can build your answer in the app Caser is fully offline, private, and built to fit into whatever five minutes you have. No accounts. No tracking. No data leaving your phone. Just a fast native iOS app that gets out of your way between the prompt and the next rep. Get ready for your case interviews, sharper structured thinking, or just better brainstorms: open Caser and start drilling.
