Would you like to improve your drumming? ProJammer will have you jamming like a pro in no time! ProJammer represents a revolutionary way to learn new drum skills quickly. All you need is your drum kit, some headphones and ProJammer – it’s like having your own private drum instructor, plus a backing band! ProJammer is a play-along app like no other: - ProJammer contains multi-track original music (with real instruments, not fake MIDI imitations) that you play along to. - The original play-along music is specifically written to complement each associated drum lesson. - The play-along music is provided in loop form. The loops allow you to get in the groove and play until you feel comfortable, without ever needing to restart the song. - Each musical loop is accompanied by a drum transcription that corresponds to the drum part in the musical loop. - You can change the loop speed! Play along with the loop at a slow speed to learn the pattern, then accelerate the loop to build your chops! - You can selectively mute instruments and the built-in metronome to match your learning objectives. For each loop, you can start by listening to just the drum track to get familiar with it. Next, add the other instruments (guitar, bass, and keyboards) with a few clicks and play along! When you get more confident, you can remove the drum track (and also the metronome), and it’s like you are playing with a backing band! Play the pattern that is transcribed, or improvise your own part! ProJammer is a free app that contains five built-in musical loops plus transcriptions. The built-in loops cover Rock, Funk, World, Blues, and Latin beats. Additional packs of loops can optionally be purchased via in-app purchase.

Verdict

The call

The clearest difference is rating: Vocal Remover at 4.4 against ProJammer's 3.9. Vocal Remover also leads on ratings volume (8.1K vs 7). ProJammer's advantage is ads (none vs shown) and review sentiment (77% vs 50%). On price, update cadence, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Vocal Remover holds the better App Store score, 4.4 against 3.9. That said, the two scores are not equally well evidenced: Vocal Remover has 8.1K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 77% of ProJammer's written reviews are positive against 50% of Vocal Remover's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 2 weeks. The most recent releases landed on November 2, 2026 and November 7, 2026 respectively.
