All You Can ET is a game designed to train cognitive flexibility, a subskill of executive functions. Cognitive flexibility involves inhibiting a prior perspective and considering a new perspective (Diamond, 2013). Players need to apply frequently changing rules to give differently colored aliens the right food or drink they need to survive. How does this support learning? Executive functions refer to a set of top-down, goal-oriented cognitive processes that enable people to control, monitor and plan behaviors and emotions. Miyake and Friedman’s model supports a unity-and-diversity view of EF in that it incorporates the three distinct but related components of EF: inhibitory control, task-switching and updating (Miyake et al., 2000). What is the research evidence? Our research suggests that All you Can ET is an effective way to train Cognitive flexibility. Homer, B.D., Plass, J.L., Rose, M.C., MacNamara, A.*, Pawar, S.*, & Ober, T.M. (2019). Activating Adolescents’ “Hot” Executive Functions in a Digital Game to Train Cognitive Skills: The Effects of Age and Prior Abilities. Cognitive Development, 49, 20-32. Research has found that EF is related to performance in literacy and math along with long-term gains in school performance and academic readiness (Blair & Razza, 2007; Brock, Rimm-Kaufman, Nathanson, & Grimm, 2009; St Clair-Thompson & Gathercole, 2006; Welsh, Nix, Blair, Bierman, & Nelson, 2010) and that disparities in EF among preschool children from low-income versus high-income homes may contribute to the achievement gap (Blair & Razza, 2007; Noble, McCandliss, & Farah, 2007). This game is part of the Smart Suite, created by New York University’s CREATE lab in collaboration with the University of California, Santa Barbara, and The Graduate Center, CUNY. The research reported here was supported by the Institute of Education Sciences, U.S. Department of Education, through Grant R305A150417 to the University of California, Santa Barbara.

Both are free to download. Brain Test sells 2 one-off in-app purchases. All You Can ET asks for nothing beyond the download.
All You Can ET holds the better App Store score, 4.8 against 4.1. That said, the two scores are not equally well evidenced: Brain Test has 71 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 72% of Brain Test's written reviews are positive against 67% of All You Can ET's, so the app with the better star average is not the one people write more warmly about.
Brain Test ships an update every 2 weeks, All You Can ET every 39 months. The most recent releases landed on October 16, 2026 and October 6, 2026 respectively.
