About this app

KnowCard turns professional subjects into bite-sized, expert-reviewed flashcards you actually remember.

Study the way that sticks: answer a card, rate how well you knew it, and a spaced-repetition engine brings it back at the right moment — so knowledge compounds instead of fading.

• Expert-reviewed content — every card is checked for accuracy, not crowd-sourced.
• Deep coverage of SAP and IT operations (administration, security, transport, HANA, Linux and more), with new fields added over time.
• Learn as you test — short sessions that fit between meetings.
• Track real progress, favorite the cards that matter, and focus on what you haven't mastered yet.
• Pro+AI unlocks the full library and AI-powered explanations.

Whether you're preparing for a role, keeping your skills sharp, or going deeper in your field — grow as you go, one card at a time.
