Most guitar apps help you learn songs, but struggle to help you manage them after. Instead of forgetting sonogs over time GuitarDex tracks your practices, reminds you what needs attention and makes maintaining your personal catalog enjoyable.
It combines a Pokémon inspired leveling system with practical tools like imported tabs and chords, a tuner, metronome, chord finder with a scale mode, and a chord editor for custom chord sheets.
Frequently being updated and used daily.

- Earn XP by logging practice sessions
- XP scales with song difficulty, practice duration, your highest level reached, and streak bonuses
- Songs progress through statuses: Seen → Learning → Refined → Mastered
- Optional XP boost multiplier (up to 3×) to tune how fast you level up
- Pin frequently-played songs to the top of the library, with status filters and search
- Custom filter chips (by artist, difficulty, or tuning) and sort by recent, level, or age
- Autotune filter — a smart chip that surfaces every song matching the tuning of your last practice session, so you can see what you can play right now without retuning
- Songs decay if not practiced within grace periods
- Harder songs decay faster, but decay resistance scales with total practice sessions. The more you've played it, the slower it fades
- Songs that reach Refined have a minimum floor at level 5
- Songs that reach Mastered never decay below Refined
- Decay rate is adjustable (0.5×–2×) so retention can be as forgiving or as demanding as you like
- Decay can be toggled off entirely from settings
- A stats dashboard that visualizes your practice history with charts

- Interactive SVG fretboard spanning 12 frets, with configurable tuning and capo

- Search mode — chords — pick a root, quality, and optional bass note, and it generates up to 20 playable voicings ranked by how clean they are to fret
- Search mode — scales — pick a root and a scale type (common / pentatonic / modes) and it maps the scale across the whole neck, then breaks it into hand-position boxes you can cycle through
