Deliberate practice
Hey, welcome in.
Fretster was born from my real frustration: wasting time every session deciding what to work on. Now it's a platform that gives you structure without rigidity so every minute brings you closer to your goal, whatever path you follow — online or in-person academies, your own course, or your own route — and helps you track your progress without losing momentum. Free, no sign-up required.
Whether you teach in person, run an academy, or have a YouTube channel: define a course once, everyone follows it at their own pace — and each time they practice you see what they did and how they felt, closing the loop.
A short, focused drill. You play it daily, log how it feels and the BPM
A guided set of exercises with warm-up. 15–30 min.

How it works
The practice loop
- 1 minuteset a challenge with a date.
- 5 minutes a dayplay today's drill and log your BPM.
- 1 weekcheck Progress and watch the curve rise.
- 1 monthmark the challenge done and set the next.
1. Set a challenge
In your profile, add a goal with a target date: "Hotel California clean by July 1". The countdown shifts color as it nears.
2. Practice today's drill
The home shows today's drill. Hit Start, play to the metronome, log your highest clean BPM. The streak counts the days you show up.
3. A routine that rotates
The week rotates: a different drill each day so you don't plateau. Exercises holds the full catalog — scales, technique, chords — filterable by difficulty.
4. See your progress
Progress plots your BPM per drill, shows your habit calendar (green = you showed up), and suggests what to hit next. The improvement is in the numbers.
5. Tones and loop
When you want a break from the metronome: amp presets by artist and the YouTube Loop Trainer to repeat any passage.
6. Optional: cloud sync
Without sign-in, your progress lives only here. Sign in with Google and it syncs everywhere you use the app. No emails, no spam.
FOR ACADEMIES & TEACHERS
Scale your methodology without losing individual tracking.
Your students practice more. You know what they did, how they felt, and who needs attention — before you walk into the lesson. Whether you teach online, in person, or run a community — Fretster connects what happens in class with what happens between classes.
How it works:
- See who's practicing and who's not — before each lesson
- Send exercises that show up directly in the student's app
- Define a course once — every new student inherits it and every practice session is logged with their feeling and BPM
- Schedule lessons via Google Calendar — invites and reminders send automatically
- Students join via a WhatsApp link — zero friction
- Every morning, your Inbox shows you at a glance: who's on a streak, who's stalled, who finished their homework, who hit a new BPM record, and today's lessons
Your academy, your name, your brand.
