About this app

■ A train that writes letters!

RailMoji is a tracing app with a twist: wherever your child's finger goes, a railway is
laid down and a little train rolls along it, clickety-clack. Finish a letter and a flower
stamp appears — and the wish to do just one more grows on its own.

■ What there is to trace

· Shapes and lines (the very first pencil strokes)
· Numbers (1 to 10)
· ABC — capital letters (26)
· abc — small letters (26)
· Spanish, Portuguese and French each get their own accented letters too
· And as a bonus: Japanese hiragana and katakana (92 characters)

■ The right stroke order, from the very first try

Every character comes with a stroke-order guide. An arrow gently shows which way the hand
should go, so even a first attempt is written in the correct order.
No red crosses, no buzzers — nothing is ever marked wrong. Little ones can try again as
many times as they like without ever feeling they failed.

■ Collect the trains

Every finished letter earns flowers. Spend them on the train gacha to collect different
trains, which then ride along with your child on the next letter.

■ Made for small children

· Playable before they can read: pictures and colours carry the screen
· Sounds and a voice that reads each character aloud, so the sound is learned too
· Rewarded video ads only, behind a grown-up confirmation your child can't tap by accident
· No personalised ads (child-directed settings)
· A parental gate in front of purchases and contact
· No personal data collected — progress is stored only on the device

■ Premium (one-time purchase)

Every letter is free from the start. Premium doesn't unlock content — there is no
content to unlock.
One purchase removes the ads and turns the daily free gacha into two pulls a day.

Turn letter practice into train time.
Start free, and set the train rolling on the letter "A".
All letters free. Trace with a train, learn the right stroke order. Age 3+.
