About this app

■ Practice Hiragana with Trains! An Educational App for Learning to Write While Playing
"RailMoji" is a completely new tracing practice app for Hiragana, Katakana, Numbers, and the Alphabet, where children trace letters by running a train on tracks.

Simply trace the screen with your finger, and the tracks will be laid accordingly, with your favorite train rumbleing along! Children receive a "perfect score" when they finish writing, making it a fun and engaging experience that will keep them wanting more.

Start with the free version and try running the train from "a"!

■ Four Reasons Why "RailMoji" is Chosen
1. Naturally Learns Correct Stroke Order
Easy Arrow Guides: All letters come with stroke order guides. Even first-time learners can write with the correct stroke order without getting lost.

Safe "Zero Deduction" Design: No X marks or unpleasant buzzer sounds for mistakes! Even young children can try again and again without frustration.

2. Keeps you engaged! A fun "Train Gacha" to collect!
Clear the letters to get "Hanamaru" marks!

Use the collected "Hanamaru" marks to spin the gacha and collect various trains.

You can make your favorite collected trains your tracing partners and run them together.

3. Supports a wide range of letter learning! Abundant content included
Includes a curriculum that can be used for a long time, tailored to your child's developmental stage.

Hiragana: 46 letters ("aiueo")
Katakana: 46 letters ("aiueo")
Numbers: 1-10
Alphabet: Uppercase ABC and lowercase abc
First Pencil Practice: Lines and shapes (perfect for warming up to tracing)

4. Safe and secure design for young children and parents
Picture and color-based screen: Even toddlers who can't yet read letters or numbers can intuitively play on their own.

Text-to-Speech: Learn not only how to write but also how to read characters with sound effects and voice guidance.

Secure Security & Privacy:
No personal information is collected (learning data is stored on the device).

Personalized ads are hidden with child-friendly settings.

Includes "Parental Gate" to prevent accidental operation (for viewing rewarded video ads, making in-app purchases, and inquiries).

■ Recommended for: (Children and Parents)

* For children aged 3, 4, 5, and 6 (preschool, kindergarten, and elementary school) to begin learning to read and write.
* For children who want to get a head start on learning hiragana and stroke order before starting elementary school.
* For children who love trains, bullet trains, tracks, and vehicles.
* For children who dislike or quickly get bored with paper workbooks and hiragana cards.

■ Pricing Plan
Basic gameplay is free.

Premium (one-time purchase): All stages are unlocked with a single purchase, and ads are completely removed (this is not a subscription, so there are no worries about additional charges).

There are no unexpected charges from gacha (loot boxes).
