Koala is the ultimate pocket-sized sampler. Record anything with your phone's mic or load your own sounds. Use Koala to create beats with those samples, add effects and create a track! Koala's super intuitive interface helps you make a track in a flash - there is no brake pedal. You can also resample the output of the app back into the input, through the effects, so the sonic possibilities are endless. Koala's design focuses totally on making the music-making process instant, keeping you in the flow and keeping it fun, not getting bogged down by pages of parameters and micro-editing.

Verdict

The call

The clearest difference is in-app purchases: DRM at none against Koala Sampler's 8. DRM also leads on rating (5.0 vs 4.8) and price ($1.99 vs $4.99). Koala Sampler's advantage is review sentiment (88% vs 57%) and update cadence (every 3 weeks vs every 7 months). On ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

DRM holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Koala Sampler has 1.4K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 88% of Koala Sampler's written reviews are positive against 57% of DRM's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Koala Sampler ships an update every 3 weeks, DRM every 7 months. The most recent releases landed on September 25, 2026 and September 10, 2026 respectively.
