U-Lang is a visual sound instrument that can be used to create digital sound scapes on touch based devices. Its important aspects are the reduced set of grammar, a limited set of input methods. The goal is to create complex processes using very simple, yet very precisely controllable operations. The purpose of the application is to make the nature of sounds, scales and melodies accessible to both novices and experts in a unique way. Apart from musical concepts, U-Lang has a unique gestural interface that changes the way we interact with time & rhythm.
Verdict
The clearest difference is rating: Thesys at 4.7 against ULang's 3.8. Thesys also leads on ratings volume (85 vs 4). ULang's advantage is in-app purchases (none vs 1) and review sentiment (71% vs 59%). On price, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Thesys sells 1 one-off in-app purchase. ULang asks for nothing beyond the download.
Thesys holds the better App Store score, 4.7 against 3.8. That said, the two scores are not equally well evidenced: Thesys has 85 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 59% of Thesys's written reviews are positive against 71% of ULang's, so the app with the better star average is not the one people write more warmly about.
