Sight-read as fast as you play.
You already play. Take the 20-second test below, then let NoteTrail drill the notes that slow you down.

How fast do you read?
You have twenty seconds to name as many notes as you can, under the same rules as Speed Run in the app.
On a computer, the letter keys work too.
What NoteTrail drills
Every reader has a few notes that stop them.
NoteTrail keeps this list for every note you play. The ones you miss or answer slowly come back sooner, and the ones you know come up less.
In the app it's called Practice next. It lives on the Progress tab, and it's free.

Least accurate first, then slowest.
Play the answer on your own piano.
The iPhone mic hears the note, so you don't need a MIDI cable or an adapter.
It works on acoustic and digital pianos. Audio is analyzed on your phone and never recorded.
Real Piano mode is part of NoteTrail Pro, free for the first week.
The trail
Seven tiers to climb. Three are new.
Tell NoteTrail you're Improving, Intermediate or Advanced, and it starts you on the tier that fits. Every tier sits on the home screen, one tap away; the ones marked Pro need a subscription.
Speed Run, sixty seconds against your own best, runs on every tier except Intervals.

For teachers
A practice summary you can read in ten seconds.
Your student sends it with one tap from the Progress tab: accuracy, streak, each clef, and the exact notes that need work.
There are no student accounts or rosters to manage. Practice data stays on the student's phone until they choose to share it.

Questions
Do I need a MIDI keyboard?
No. NoteTrail listens through the iPhone microphone and recognizes the note you play on an acoustic or digital piano. If you'd rather not use the mic, the on-screen keyboard always works.
Is this for beginners?
Not really. NoteTrail is built for people who already play but read too slowly, and for the teachers working with them. You choose your starting level and skip the first-lesson material.
What's new in 1.1?
Three Pro tiers (Grand Staff, Bass Sharps & Flats and Ledger Lines), Speed Run, and Practice next on the Progress tab. If you already have NoteTrail, update it from the App Store.
Does my audio leave the device?
Never. Pitch is detected on your iPhone in real time, and audio is never recorded, saved or uploaded. The microphone runs only while a practice session is on screen.
