The compare
How do you know you're actually improving?
Your memory of a take starts cleaning up the mistakes within about thirty seconds. That's the 30-Second Memory Window, and it's why “that felt fine” is useless feedback.
A recording doesn't clean anything up. Put today's take next to last week's, flip between them, and you'll hear exactly what changed.

Last week the fill in bar five ran ahead of the beat. Today it lands where it should. You'd never catch that from memory.

Same notes, cleaner attack. The level stops jumping around every time you dig in.

Take 1 chops the long notes short. Take 4 lets them ring into the next bar.

Get early accessVoice Memos vs RunThrough
Why use RunThrough instead of Voice Memos?
Voice Memos is great for catching an idea before it's gone. It was never built to tell you whether you're getting better, so the clips pile up and you stop opening them. The difference isn't the recorder. It's what happens after you hit stop.
| Compared on | Voice Memos | RunThrough |
|---|---|---|
| Made for | Grabbing an idea before it's gone | Working a part until it's better |
| Where takes end up | One long list of "New Recording 214" | Filed under the song or lesson you're practicing |
| Hearing what changed | Play one clip, open another, try to remember the first | Two takes side by side. Flip A/B mid-phrase |
| The hard bars | Scrub back by hand, again and again | Loop the same bars in both takes |
| Practicing with a lesson | Switch apps, lose your place | YouTube lesson and your takes on one screen |
| Notes | Rename the file and hope you remember why | A quick note on every take, while it's fresh |
The Momentum Loop
How RunThrough helps you break through practice plateaus
Plateaus usually aren't a talent problem. They're a feedback problem: you can't fix what you can't hear. RunThrough is built around one short loop we call the Momentum Loop, and every lap starts a little higher than the last.
01 / Record
Repeatable reps
Same bars, same tempo, one take. Short enough that you'll actually do it again tomorrow.
02 / Compare
Honest checkpoints
Today's take next to last week's. Your ears make the call, not your mood.
03 / Adjust
Compound gains
Fix the one thing you heard, then go again. Small fixes stack up into weeks of progress.
A real session
How do you use RunThrough in a real practice session?
Open the song, loop the hard bit, record a take, compare. The whole thing takes about as long as tuning up.
02 / Loop
Loop the sticky section with the video
- Turn a YouTube lesson into chapter steps you can practice.
- Set loops on the hard bars and stay in the material.
03 / Record
Record one honest take
- Hit record and play. Nothing between you and the take.
- Add a quick note while the take is still fresh in your ears.
04 / Compare
Compare and hear what changed
- Put this week next to last week and flip A/B.
- Trust the playback over your memory of how it went.
Everywhere you practice
Record on your phone. Review at your desk.
Your takes follow you between iPhone, iPad, and Mac, so the one you recorded on the couch is waiting when you sit down to listen properly.
iPhone
Record where you practice. One tap, straight from the song you're on.
Mac
Line up every take from the week on the big screen and actually listen.
iPad
Lesson on screen, take running underneath. Loop the video's hard bars.
Why I built it
I'm not a pro. I'm a guitarist who wants to be as good as I can be.
I'd spend a week on a part, sit down to play it, and sound exactly the same. I never really knew if I was getting better or just putting in time.
So I went deep on how practice actually works: the research on deliberate practice, and what separates the reps that move you forward from the ones that just burn time. The short version: you need feedback you can trust, and your memory of how a take went isn't it.
RunThrough is what came out of that. Record a take, put it next to one from last week, and hear what changed. It's the only practice app I've found that puts two takes side by side, on iPhone, iPad, and Mac.
If you practice a lot and still aren't sure it's working, I built this for you.

FAQ
Questions musicians ask about RunThrough
Straight answers about the app, pricing, and how it's different from what's already on your phone.
Why use RunThrough instead of Voice Memos?
On iPhone that's usually Voice Memos; on Mac it might be QuickTime, GarageBand, or whatever you already use. Those tools are fine for a quick capture, but they were never built for practice as a loop. Your clips pile up with useless names, there's no side-by-side compare, and jumping from last week to today is a chore. RunThrough is one place to record, put two takes side by side, and hear what actually changed.
Why would I pay when my phone records for free?
You're not paying for a microphone. You're paying for the compare step, which is the one thing your phone and the other practice apps leave out: two takes side by side so you can flip between them and hear what changed. Plus organization, and less time lost digging through files or moving audio into a DAW. RunThrough is built so you keep a habit of record, compare, and improve, not record-and-forget. In the app it's $4.99/mo or $39.99/yr (about $3.33/mo), each with a 14-day free trial, or a one-time Lifetime purchase at $119.99 if you'd rather buy it once. These are introductory launch prices and will go up after launch.
What changes about my practice habit?
Instead of record-and-forget, you get a short loop: record a focused take, compare it to the last one, and know what to fix next. That's the habit that makes improvement audible instead of guessed.
I don't really record myself. Why start?
Because without a recording, all you have is your memory, and memory cleans up the mistakes within about thirty seconds (what we call the 30-Second Memory Window). You finish a part, it felt fine, and you move on with no real idea whether it changed. Record one quick take of whatever you're working on and you can compare it to last week and actually hear the difference. That's the whole habit: one take, then compare. It's the difference between knowing you're improving and hoping you are.

What is RunThrough?
RunThrough is a music practice app for iPhone, iPad, and Mac that helps you record takes, compare them, and hear your progress over time. It's built for musicians who already practice and want honest feedback from their own playing.
