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.

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!

Nice app

I agree with one of the other reviewers that the strength might be overstated (including for humans; I won't tell you what Hiarcs rates me but there's no way I'm that good). However it's a fantastic training program and a handy opponent. I like it a lot and I've already recommended its training features to several people.

Raised the Bar!!

For those that are familiar with chess programs, Hiarcs needs no introduction. It comes with a strong pedigree and many championship awards. Needless to say, I was anxious to see that program in the app store.

There are many very good chess programs for the iphone now, but Hiarcs is just a cut above. It shares all of the features, except one, of the top programs. The one shortcoming is that you cannot download pgn games, and I hope that it is resolved in an upcoming update since that would make an already great game even better.

For me, it came down to Fritz and Hiarcs. Hiarcs wins from an engine strength standpoint, but how badly do I need to get smashed when I'm an average player (but even GM's will find it challenging!). The difference is in the extra features that make playing a game more enjoyable. Things like engine playing style, book styles, and adapting its strength to me. All of these features also aid my development for my improving game.

So, if you are looking for a strong program, features to make the game enjoyable to play and learn, and pleasing graphics and intuitive play, then look no further than Hiarcs Chess.
