LoAdKer is a novel rhythm event generator that is based on fractal sequences. Unlike most other drum-mahines, LoAdKer has the ability to create complex patterns that evolve over time, sounding similar but not exactly the same. The result can be anything from minimal, repetitive beats to sonic mayhem, aided by the real-time effects that add an extra dimension to the sound. LoAdKer has been designed as a performance tool and, in fact, it is being used as such by the developer himself. Thus, it is remarkably stable and easy to use either in a performance or in a studio. It can be especially useful to those who write electronic, electroacoustic, experimental music, IDM, glitch, noise etc. Features: - four instruments: kick, hihat, fx1 and fx2 with synth and sampler audio engine, filter, reverb, delay controls and more - every instrument has an extra control that determines the degree of their chaotic behaviour (this is where the real fun begins!) - most parameters can be automated in real-time by drawing custom curves, which can be time or beat - based, looped or one-off - adjustable audio buffer size (128 to 4096 samples) - multiple sample rate support (subject to hardware capabilities): 44.1, 48, 88.2, 96 and 192kHz - IAA/AudioBus™ and Ableton Link™ compatible -performance recording - import sounds from and export to Audio Copy™ and AudioShare™, export audio to Dropbox and exchange sounds over iTunes
Verdict
The clearest difference is in-app purchases: LoAdKer at none against Thesys's 1. LoAdKer also leads on review sentiment (70% vs 59%) and iOS requirement (12.0 vs 17.6). Thesys's advantage is rating (4.7 vs 4.3) and ratings volume (85 vs 13). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Thesys sells 1 one-off in-app purchase. LoAdKer asks for nothing beyond the download.
Thesys holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Thesys has 85 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 59% of Thesys's written reviews are positive against 70% of LoAdKer's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on October 16, 2026 and October 13, 2026 respectively.
