Zetamac Arithmetic Practice vs eincard

Zetamac - A mental math practice app used in the Quantitative Finance world.

Less scrolling. More remembering. eincard turns the moment you open a distracting app into a chance to study. Each time you open a selected app, review a few flashcards. Then continue intentionally, or decide you no longer need to scroll. Unlike a rigid app blocker, eincard does not lock you out. It adds useful friction. Screen time becomes active recall, and the habit of checking your phone becomes a cue to learn. HOW IT WORKS 1. Create or import a flashcard deck. 2. Choose the distracting apps you want to gate. 3. Follow the guided setup for an Apple Shortcuts automation. 4. Review cards whenever you open a selected app. 5. Continue after studying or return to what matters. STUDY SMARTER • Remember more with spaced repetition. • Swipe cards into known and still learning piles. • Reverse cards to practice both directions. • Set daily study limits for each deck. • Star important cards and organize decks into folders. • Track reviews, streaks and progress over time. BUILD BETTER PHONE HABITS • Add a study gate before social media and other distracting apps. • Choose how many cards each app asks you to review. • Set an active schedule for school, homework or exam sessions. • Use a short launch pass so intentional app switching stays smooth. • Pause every gate when you need a break.
