Influent is a Language Learning Game focusing primarily on vocabulary acquisition and pronunciation. It was initially developed in Japan at the University of Tsukuba's Entertainment Computing Laboratory under the Monbukagakusho Government Research Scholarship. Inspired by Dreamcast titles of old (namely Shenmue and Toy Commander) Influent immerses players in a fully interactive 3D environment where the names for absolutely every object in the game can be gleaned with a single tap! In fact, even more information can be learned with a double-tap! Every door, drawer, and cabinet can be opened with a tap-and-hold, revealing more things to be learned! Packed to the brim with hundreds of native audio pronunciations (painstakingly recorded specifically for this game), Influent offers players of all ages a unique opportunity to enjoy learning both vocabulary and pronunciation in the language of their choice.

Verdict
The clearest difference is rating: Influent Language Learning at 4.3 against Kbook's 3.3. Influent Language Learning also leads on ads (none vs shown) and review sentiment (57% vs 42%). Kbook's advantage is update cadence (monthly vs every 6 months). On price, in-app purchases, monetization model and device support there is nothing between them.
