## What is Piano & Stickers?

At first, I went looking for an app like this.
One where a parent can properly adjust the level,
the piano sound is the real thing, there are no ads,
and — why not — there's even a reward.
An app with everything on my wish list, all in one.
I couldn't find it.
So I thought, fine, I'll make it myself — and that's how this app came to be.
I'd be delighted if it helps other parents in the same boat.

① Good for
・Your child has started piano lessons, but pitch still doesn't quite click
・You're looking for ear training that's actually fun to keep up
・You want an app with no ads and no tracking
・You want a gentle nudge toward "I'll practice on my own"

② Three simple steps
1. Listen to the example note
2. Tap the key you think makes the same sound
3. Get a sticker for a correct answer and collect it in the sticker book
No reading required to play.

③ Built to feel safe
・No ads, ever
・No tracking
・No personal data collected
・No sign-up or login needed
・Purchases, level settings, and every bit of explanatory text live only inside the settings screen — never one accidental tap away

④ Chord listening, too
We added a chord mode for guessing two- or three-note chords.
Great for kids who've already gotten confident at ear training.
Honestly, it's a level even I can't always ace myself.

⑤ Free to start
Play with the treble-clef Do-Re-Mi-Fa-Sol-La-Ti-Do,
12 everyday stickers, and a 1-page sticker book.

⑥ Premium
Want more? A one-time "Premium Unlock" adds:
・Note matching across two octaves, C3 to C5 (black keys included)
・140 stickers
・A 10-page sticker book
・Chord mode Level 2 and beyond

Rooting for your child's first steps at the piano, wholeheartedly.

## Version history (last 5 releases)

### 2.2 — 2026-08-22

Sticker book pages now turn more naturally, like a real book. The free version can browse pages with the buttons, but stickers cannot be placed on locked pages.

### 2.1 — 2026-07-29

Thanks so much for playing Piano & Stickers!

In single-note mode, your child can now choose the difficulty: treble clef, bass clef, or both.
Chord mode has two new levels too — one for telling perfect fifths apart, one for perfect fourths.
We also added stickers you can only earn in chord mode — special "water stickers."

I hope these new additions bring a smile. Thanks, as always, for playing Piano & Stickers.

・Added Chord Mode for listening to two or three notes.
・Added Chord Levels 1-3, from white-key practice to major and minor triads with black keys.
