StrumForge
Guitar practice app for iPhone and iPad
A practice app that gets you playing before the spare moment disappears.
StrumForge keeps daily guitar sessions short to start and easy to stay in. Generate a progression, start the groove, and follow the diagrams in tempo on your phone or tablet.
- Built for warm-ups, improvisation, songwriting, and repeatable daily practice
- Portrait controls for quick setup, landscape views when you want more visual context
- No account required to start, and no ads getting between you and the guitar
Free to download on iPhone and iPad, with optional StrumForge Pro subscriptions.
Daily use
Built around the sessions that actually happen
Pick up and start
Open the app, choose a key or leave it loose, hit generate, and you have something playable before the warm-up window closes.
Stay in one groove
Use the same progression for rhythm work, chord changes, scale practice, or short improvisation passes without bouncing between tools.
Adjust only what matters
When the harmony is close but not quite right, lock chords, swap shapes, add chord color, or move one diagram without rebuilding the whole loop.
Play-along
The progression keeps moving while you play.
The app is not just a static diagram viewer. Start the groove and the active chord card highlights in time, so timing, strumming, and chord transitions all stay tied to the same pulse.
- Beat pulse and groove controls keep the loop readable at a glance.
- Chord playback and guitar tone options help the session feel musical instead of mechanical.
- Highlighted cards make it easier to stay with the form when you are practicing alone.
Orientation
Portrait when you want quick control, landscape when you want more context.
In portrait, the app stays compact and easy to launch anywhere. In landscape, it becomes easier to track longer progressions and explore the lower panel where you can swipe from the scale diagram to the chords inside the current key or mode.
- Use portrait when you want a fast setup and a tight working surface.
- Use landscape when you want more room for progression tracking and theory context.
- Works well on both iPhone and iPad when you want a bigger practice surface.
Hands-on control
You can move the diagram layout when your eye wants a different order.
Some practice tools force one rigid progression layout. StrumForge lets you drag a chord diagram into a new position, which helps when you want the screen to match the order you are mentally hearing or physically preparing to play.
- Reposition a chord without losing the rest of the loop.
- Combine movement with chord locks and shape swaps when one part of the progression needs extra focus.
- Useful when you want a phone-sized layout to feel less cramped and more intentional.
Keep it simple
A phone practice tool should stay out of your way.
- Choose open chords, barre chords, triads, or power chords.
- Add sevenths, suspended chords, and add9 color when you want a different texture.
- Use built-in mode and pentatonic views when the session turns into solo practice.
- Upgrade to StrumForge Pro for favorites, sharing, tuner, dark mode, default settings, and individual scale diagrams.
- Turn on left-handed diagrams when that matches the way you read the instrument.
- Reset quickly and start over when the current setup has gone too far.
