Stop retreating to the easy part of the fingerboard. Walking Bass Trainer makes you find chord tones across the whole double bass — in time, in tune, and without falling back to the positions you already trust. I built it because I had exactly that problem. I play double bass, and I write software. I realized that when practicing walking lines I'd happily use the parts of the fingerboard I knew well, while the awkward positions stayed awkward. So I built something to break the habit of retreating to familiar positions. Walking Bass Trainer deals you a chord, keeps time, and listens through your microphone while you walk. Find a chord tone and it lights up. Play it sharp or flat and you see by exactly how many cents. Then the next chord arrives. A new puzzle every bar. You're walking at 120 BPM. Dm7 appears. G7 is already waiting underneath. You find F. It lights up. You reach for C higher up the neck. You're 17 cents sharp. Next bar. G7. Keep walking. It won't give you walking bass lines to memorize. That's deliberate. This isn't a walking-bass course. It's for players who understand chords but want the connection between chord symbol, sound and fingerboard to become automatic. Because on the stand, nobody waits while you work out where the 7th is.

Verdict

The call

The clearest difference is price: Quartet 2 at Free against Walking Bass Trainer's $2.99. Quartet 2 also leads on rating (4.8 vs 3.7) and ratings volume (59 vs 3). Walking Bass Trainer's advantage is in-app purchases (none vs 5) and update cadence (every 3 days vs every 2 months). On ads, monetization model, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Quartet 2 holds the better App Store score, 4.8 against 3.7. That said, the two scores are not equally well evidenced: Quartet 2 has 59 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 89% of Quartet 2's written reviews are positive against 100% of Walking Bass Trainer's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Quartet 2 ships an update every 2 months, Walking Bass Trainer every 3 days. The most recent releases landed on November 5, 2026 and November 6, 2026 respectively.
