Comments on SaioApp - The Othello engine for Android

★★★★★ J K · May 30, 2021
I love this elegant app. It's like playing Othello with God; if you ever win, you know you're either lucky, improving, or some combination of both. My only problem is, I can't figure out how to play as white. Surely it's something obvious that I'm just overlooking.
★★★★★ Ben Seeley · Jul 30, 2018
As a World Champ of Othello, of all the apps I have tried, Saio is my new favorite Othello app! The endgame quizzes are my favorite part. Saio also has an incredibly strong engine. Nice graphics, mostly easy to use, and cool technical features.
★★★★★ Jeff · Feb 8, 2024
Neat tool. Needs a few tutorials beyond the manual, but the stat listings per play make it worth the cost. Would be fun if I could link my game history directly to app.
★★★★★ may gon · Aug 14, 2019
It was a huge challenge for me to defeat this saio app, the developer is great for making this app, nice graphics. Keep it up
★☆☆☆☆ Olli Makkonen · Sep 29, 2022
The app keeps asking permission to make calls with my phone. When I obviously do not accept, the app crashes after launch.
