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 Chess has a full range of realistic weaker opponent strengths and playing styles catering for players of all abilities from absolute beginners to Grandmasters. On the weaker playing levels HIARCS will make human-like mistakes appropriate to the level of play and this together with the integrated coach advice, assessments and alerts allow you to learn and improve quickly. HIARCS also monitors your chess performance and provides you with an Elo chess rating which tracks your chess ability in every game. It can continuously adjust its playing strength to give you challenging but beatable opponents as you improve.

HIARCS Chess will save battery life by using much less energy on the weaker levels, allowing more playing time on long journeys etc.

the real madra ,

great chess app - let down by substandard graphics

great app. where other chess programmes will either whop you on the difficult levels or throw the game away idiotically on the easy levels, HIARCS really seems to 'do what it says on the tin' as regards matching your playing abilities. even when playing drunk, or at my usual plankton IQ level, every game is a tough one but almost magically well-matched. you never feel [as i've found with other chess apps] that either:

A: the computer is unbeatable
B: the computer is making stupid moves deliberately to let you win.

my one criticism of the game would be the graphics [and application icon - yuk!]. most of my fellow reviewers seem to think they're great. personally i find them a bit fugly, myself. if you want to see graphics on a chess app done right, check out deep green lite.

Outstanding chess app - well worth the money

HIARCS is an outstanding chess application for players of any level. My game has improved significantly since I purchased it six months ago after years of stagnation. The analysis function provides an accurate assessment of a position almost instantaneously and the available levels literally range from world champion down to beginner. As a very average club player I'm happy playing against a rather low setting of about 1350 Elo which results in a fair spread of wins, draws and losses. The openings repertoire covers all the recognised ones as well as quite a few obscure variations, e.g. the Sargasso and St George Defence which I hadn't ever heard of. This results in a great variety of gameplay. If anything I would say the 1350 level is stronger than a human player of that rating, but that doesn't matter as after a few adjustments anyone can soon find a suitable setting to match their own playing strength. I've always found the app very easy to use and the latest version appears to have fixed an occasional issue I used to have where the HIARCS clock ticked down to zero without a move being made in a straightforward position. This is definitely a 5 star app.

Not Good Enough

Hiarcs is just an average chess engine which lacks some very essential functions and features. The engine shows only one single analysis line as if there is no other move and line to choose from. Other engines display at least three analysis lines. There is no arrow to indicate the best moves. Also, there is no indicaton of the percentage of games played in any given openings. Hiarcs does not have backward and forward buttons to go through the moves. The engine takes too long to show the best move and also it has no voice function. Compared to many free chess apps , Hiarcs is not good enough and to pay the high amount of £9.99 for such an average app is in no way justifiable.
