Overview

Built like a study tool, not a distraction machine.

01

Due cards first

The home screen shows what needs attention now, then gets out of the way. That keeps review sessions short, obvious, and easy to repeat while Leitra takes care of when each card should return.

Home, review, repeat

02

Categories with real structure

Organize decks by topic, search within them, and manage cards with a view that feels tidy enough for serious study.

Languages, biology, history, more

Why it works

Calm confidence, not anxious gamification.

Leitra uses clear hierarchy, soft motion, and plain study logic. The interface feels premium without becoming loud, which makes it a natural extension of the Fortunex design language.

Power features

Rich cards, Excel import, reminders, and backup.

Front and back card content can be edited with richer formatting, larger decks can be brought in through `.xlsx` import, and reminders plus local backup and restore help the routine survive outside the ideal day.

Method

A memory system with a point of view.

Leitra is built on the Leitner method: answer correctly and a card moves forward; miss it and it returns to Box 1. That gives weak knowledge more repetition and strong knowledge more space, without asking you to think about the spacing yourself.

You focus on learning, answering, and moving forward. Leitra handles when information should reappear so memory can strengthen in the background with less friction.

01

Review what is due

Leitra starts from the next meaningful action instead of dropping you into a cluttered card list.

02

Move cards through six boxes

Correct answers advance knowledge, while missed answers return to the start so weaker material gets attention sooner.

03

Build durable recall

The app stretches review intervals over time so memorization becomes lighter as confidence grows and the timing is handled for you.

Screens

The product story is visible in the interface.

Review stays focused.

Flip a card, reveal the answer, then move it forward or reset it. The loop is short, direct, and easy to repeat because Leitra manages the review cadence behind the scenes.

Deck management stays practical.

Search, filter, and organize cards by category so the library grows without feeling messy.

Settings strengthen trust.

Daily reminders, appearance options, and backup controls make the app feel owned by the learner, not the platform.
