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.

HIARCS also monitors your chess performance and provides you with an Elo chess rating which tracks your chess ability in every game.

I started playing computer chess back in 1980 with Chess Challenger 7 by Fidelity Electronics. Over the years, I purchased lots of dedicated chess computers and software for the PC including: Chess Challenger 10, NOVAG Super Constellation, M-Chess, Sargon, Zarkov, Chessmaster 10th Edition, Mattel Electronics handheld, Rebel, Shredder, etc., etc., etc.! As you can see, I'm a little bit obsessed...

All this to say, HIARCS is by far the best software/app/chess computer I've ever played. It has an eerily human-like understanding of subtle positions and on the GM levels, is an absolute nightmare to play. My own game has improved immensely by serving as its punching bag, but I'm still able to easily switch it to a level that is my equal by not my superior, so I still have the joy of checkmating it or seeing it resign. This is a CRAZY STRONG chessplayer, and an absolute joy to lose to. It would have eviscerated every other chess computer or chess program I've ever owned, including the Master strength computers; all without breaking a sweat. When the ad copy states that this is true Grandmaster strength, they aren't exaggerating. Buy it! It's the best chess bargain in the world. I have it in my iPod Touch and it's a blast to carry a Grandmaster in my pocket who's always ready for a game.

Good engine, very poor UI

This is a very strong engine, but the UI is very poorly implemented. The chess sets are quite low resolution and aliased, move animation is very jarring and often moves past the target square and often times opponents move is animated while your move is still in progress. Swiping to take back move rarely works, having dedicated buttons for this would be much better. The chip icon at the bottom is quite inappropriate here and touching it does something unexpected. I think the developers of this UI could take quite a few hints from Shredder which has pretty good UI.

crash... crash... crash...

I spent 10$ just to have an application that keep crashing on every action I do! Even the first load crashed! Never been able to change options or level... at 2600 ELO, displays +1.1 after the opening, in my favor! stupid, I am not a grand master!
