How the diagnostic worksKey figures
the ecosystem
Everything you need
to progress without guessing.
A diagnosis calibrated to your hand
The Crash Test tabs are transposed onto the fretboard zone that matches YOUR measurements. What we measure is your block — not your morphology. Next: an exercise library, scored and sorted by block.
Quantified BPM tracking
Log your tempos exercise by exercise. Visualize your progress curves over 30, 90, and 365 days to target your strengths and weaknesses.
Progress, earn XP, unlock achievements
Ranked on your rate of improvement — not your absolute level. Every session earns XP, every milestone unlocks an achievement. A beginner who works can overtake an advanced player who stagnates.
Film your progress, share it
Record yourself playing while the tab scrolls on screen — the frame automatically follows your hand movement. Vertical or horizontal, ready to post on your socials.
A help chat, with guitarists and AI Guitar Heroes
Score sharing and technical mutual aid between guitarists — backed up by AI guitarists specialized by technique.
A personal page
Bring together everything you want to show about yourself in one place: a customizable page, your social networks, your bio, your gear, your photos, your feedback... The classics — but you can also showcase your social media videos and link them to a tab from your dashboard. Every visitor gets a page with different content each time.

The questions you're asking before you try it
Can an app really measure my playing?
RIFFLEX doesn't judge your musicality or your level, but your potential — the one you haven't tapped into yet. It measures physical facts: the span of your hand and between your fingers, your tempo per exercise, the time spent, your consistency. Based on your results, it pinpoints your weaknesses, shows you what's off, and suggests a training program built on that diagnosis. Numbers, not opinions.
I've already tried apps, nothing changed.
Generic apps give you generic content. RIFFLEX does the opposite: taking into account your posture, your position and the shape of YOUR hand, it builds exercises tailored to YOUR hand. Then, at the end, it takes YOUR results to suggest YOUR training program. We don't sell you 500 random exercises — we give you the right ones.
What if I find out my level is low?
The Crash Test doesn't measure your level — it locates your block (we all have one!). Two very different things. And the ranking rewards your progress and your experience in the app, not your level: everyone starts from their own measurements.
I don't have much time to practice.
"Not much time"? You do have some, and that's exactly the point. Instead of wearing yourself out for hours on exercises that don't target YOUR problem, you work only on what's blocking YOU. Less time, more result — trust me ;)
Do I need any special gear?
Not necessarily. Your guitar, your phone or your computer, and maybe a webcam. That's it.
I'd rather work alone, my own way — I already know my blocks.
RIFFLEX is built for that. Diagnostic or not, you're free: the exercise library is also sorted by block (with plenty of filters), you dig in wherever you want. RIFFLEX suggests a program to close your gaps, but you're the one driving. We give you a framework, your numbers, not orders.
