Aksar

Aksar is a free, open-source app for learning the Khmer language — and for Khmer speakers learning English or French. Whether you're starting with the Khmer alphabet or building everyday vocabulary, Aksar gives you a calm, focused way to practice every day.

The Khmer script can feel intimidating at first. Aksar breaks it down: learn each consonant, vowel, and sign step by step, with clear audio and bite-sized practice that builds real recognition.

WHAT YOU CAN DO
• Learn the Khmer alphabet — consonants, vowels, and combinations — with native-quality audio
• Build vocabulary through short, varied lessons (recognition, listening, matching, and recall)
• Practice in the direction you need: English → Khmer, French → Khmer, Khmer → English, or Khmer → French
• Hear how words and example sentences are pronounced
• Track your progress lesson by lesson

LEARN FASTER WITH SPACED REPETITION
Aksar schedules your reviews using a modern spaced-repetition system (FSRS). It shows you each item right before you're about to forget it, so you spend your time where it counts and remember more with less effort. Set a daily review goal and keep a steady, sustainable rhythm.

WORKS OFFLINE
Everything runs on your device. Learn on the bus, on a plane, or anywhere without a connection — no internet required.

PRIVATE BY DESIGN
• No account, no sign-up
• No ads, ever
• No analytics, no trackers, no data collection
Your learning progress stays on your device and is never sent anywhere.

FREE AND OPEN SOURCE
Aksar is completely free, with no subscriptions or in-app purchases. The full source code is open for anyone to inspect, learn from, or contribute to:
