Elsa is a retro style sampling keyboard with tempo based looping. Record, save, load, reverse samples with a multi octave on screen keyboard or plug in your core midi device of choice, soft- or hardware. Elsa comes with three built in effects, a reverb, a resonant filter and a sample rate/bit crusher. Samples are looped in three different modes, one off, forward and/or forward-reverse. The start and end of playback also comes in three modes, one set of start and stop for all, one set per note and/or one set per octave, allowing for many different types of samples.

Verdict
The clearest difference is price: KAiKU Control at Free against e's $5.99. e's advantage is update cadence (every 3 weeks vs every 5 months) and iOS requirement (11.0 vs 14.0). On ads, in-app purchases and device support there is nothing between them.
