HIARCS is a multiple World Championship winning chess program and the only handheld chess program in the world which has won matches and tournaments with Grandmasters. It twice won the Mercusor Cup in Buenos Aires, Argentina ahead of Grandmasters with a performance of 2900 Elo, the best chess performance rating for any handheld device in history.
In 1997 the World's strongest ever human chess player, Garry Kasparov, said "HIARCS is much better positionally than Deep Blue" and even the current World champion, Vishy Anand, in a recent interview when asked what chess program he uses to analyse with said "generally I use HIARCS".
This power enables your iPhone to play chess like a super Grandmaster, analyse games and chess problems with you, or play at whatever weakened chess strength you want from beginner to GM strength while offering numerous features to help you learn and improve as you play with HIARCS. An advanced set of coaching features helps players of all strengths improve their chess play.

Ratings and Reviews
My Favorite Chess App
HIARCS is now my favorite app. I use an iPhone SE with iOS 12. HIARCS is beautifully intuitive to run, and it shows you it’s Elo rating right on the display based on the processing power of your device. I believe it actually recognizes your phone’s CPU power. It displays 3075 elo on my smartphone. As with most chess apps, the phone can get warm or hot but this just shows the power being used. It can be reduced by features on the app to reduce power used, or by setting the phone to low power mode, or both. Naturally this will reduce it’s playing strength. Very much worth the low price!
It has improved my playing in an enjoyable way.
This program is great fun and a painless way to become a better player. My only complaint was that Hiarcs should concede, and wasn’t. By the time I was finished expressing frustration to my wife, and fellow player, it had conceded. It is a wonderful opponent, so much so that I gave my electronic chess player a name. Last, certainly not least, “Jack” is open to a game, at my playing level, anytime, anywhere. I am indebted to the developers of this delightful device. Peter L.
Most Human-Like Engine There Is
I love to play chess but as busy as I am it can be hard to find a solid 30+ minute block to play uninterrupted. HIARCS adapts to my level in a way no other engine ever has, and I’ve tried a bunch of them. It is just like playing a human, although it does fall into patterns that you eventually get used to. This program scratches the itch until I have time to play OTB or online with a human.
