Really good, but there are a few problems

Very nice app. Use all the time for tourney play. The only bad thing about it is that the reset life button on the bottom doesnt work. It does reset both to 8000, but when you subtract any life points, it actually deducts the amount from the life points it was before it was reset. like if they had 1700 lp and i won and reset, if i attacked them for 1000 then it would show 700 LP remaining. Very minor mistake in the programming. just need to update the lp value when you reset. The only other thing is the counter system. It takes a long time to put counters on this thing, so i would recommend using a dice or two.

Great app!

I really like this app. It's simple.
It would be nice if the timer worked correctly (mine starts at 9 hours).
It would be nice if the counter system were easier to use. I understand though counters are used for such a variety of things in yugioh making it highly functional for all users is difficult.
Either way, great work and keep the thought machine open and ready for counter ideas!

I compared this with iDuelPro Lite. The two offer similar features, BUT DuelCalc was much more user-friendly and simplistic to use. I'm sure the full version of iDuelPro has a ton of awesome features, but most of them seem kind of unnecessary... I absolutely love this app, use it every time I play.

I can't seem to find anything wrong with it except maybe a record keeping of lost and won games. Unnecessary, but I figured I had to suggest something in this ridiculously long review. 
