Meh, it's like everything looks fine but wanting to go deeper there is non after first layer (example right from the start, my first champion look was Alkali mid big counter is Diana, but there is only Diana jungle build... Gunfire build 😤) Edit. Now there is mid-Diana, one star more
★★★★☆Angelo Lapuz· Nov 15, 2021
I like this app because it gives me a lot of information about different champions and items in league, but i want to know what buff do those creeps and dragons in league give. Hope you put those in your app.

★★★★★Charles Vallestero· Dec 7, 2024
Very useful in every way, from looking for builds, runes, champion informations, lores and skins. Everything is in this app.
★★☆☆☆Alcier· Aug 23, 2023
This app is pretty good but just now, it recommended the most horrendous build. And frequent and high win rate builds disappeared, it now only shows one build. Lowering my rating.
★★☆☆☆austin smith· Feb 4, 2023
It's a decent app but its key feature for me is the esports tab that has vods ready for me to click, the tab regularly gets stuck on "waiting for results" and doesn't update for the leagues I follow. Very annoying
★★☆☆☆Osprey Gaming17· Feb 10, 2025
Summoner search is bugged. It's glitching and kept saying error pls fix
★☆☆☆☆Osprey Gaming17· Sep 26, 2024
I've updated the app but lethal tempo doesn't show up, and other items aren't updated
★★☆☆☆Osprey Gaming17· Jan 12, 2026
