All learning features are completely free, so you can jump in no matter what skill level you're currently at. There are no ads, but there is a paid version if you want to donate. It's got extra bonus features like speech output, synching across multiple devices, user defined study lists, etc.
Most other apps simply present you with a wall of information about one kanji after another, and expect you to wade through the whole lot in a very tedious and inefficient way.
By contrast, Kanji Tree's revolutionary approach is simple, fun, and super effective. The more you learn, the more you can explore. And the more you explore, the more your previous learning gets reinforced.
• Kanji Recognition Game.
The learning process is broken down into three natural stages. The first is a gentle introduction which trains the pattern matching area in your brain to recognize kanji shapes. By focusing on this activity to begin with, you will amaze yourself by how powerful your own learning abilities really are.
• Word Reading Game.
The next stage takes the kanji you can recognize, and teaches you Japanese words which use them. Most kanji can be pronounced in different ways, depending on which word they're used in. By learning actual words , you naturally learn the kanji pronunciations at the same time. Don't waste your time trying to memorize lists of meaningless gibberish, or obscure pronunciations you will never need.
• Word Writing Game.
The final stage to leaning kanji is being able to write them. This will lock them into your memory in a way that reading alone will never do.
• Go At Your Own Pace
Kanji Tree takes the chore out of kanji study, making it a fun and rewarding experience. You are in control at all times; study new things or revise item you've already seen, whatever suits your mood. Sit down for half an hour in the evening, or take it out for five minutes while you're waiting for a bus. Kanji Tree automatically tracks your progress and builds your personalized ideal study list, you just play the games.
Take time out to explore as much as you like. Tap on any kanji or any of it's parts to bring up the dictionary, and browse freely to satisfy your curiosity and build connections in your brain. Then just press "Back" to seamlessly pick up where you left off.
