OK — been using this thing for about a few months now and it's stuck on my phone, reckon I'd say something since someone asked me a few days back. Am based in the UK, mainly bet football and racing, a fiver here and there, so take it how you like. How I found it was honestly pretty stupid — I never could figure out what an ew payout would be once you get five places instead of three. Basically I'd eyeball it and then be surprised. Now stick my stake in first, every time, even the boring singles. The single bet calculator tool is the one I use most — type in the price and your stake and you get returns with no faffing, either odds format. Same tool covers the fiddly ones — acca and treble maths, a lucky 15, yankees, and that's where most people I know lose track. If you fancy a poke about, it's here super heinz bet example and there's no login wall, which I appreciated. One thing that genuinely made a difference were the nerdier extras. They've got an implied probability calculator that shows the overround, and there's the kelly tool — I use half kelly since full stakes are terrifying. The dutching one is decent for when I'm spreading across selections. Not all sunshine though. The interface is pretty plain — not much flash, which honestly I don't mind but some will. Phone-wise it's usable but the bigger tables make you pinch and zoom. Also there's no proper app, just the site — doesn't bother me just flagging it. Right, that's me. Doesn't cost anything, barely any ads, does what it says. Anyone who still does the maths on paper, have a look — saves me a fair few arguments with the bookie.

Right — been using this thing for about four months now and I keep coming back, reckon I'd write something up since a lad on another thread asked me last week. Am in the UK, mostly stick to footie and the horses, nothing mad, just so you know where I'm coming from. How I found it was honestly pretty stupid — I could never get my head round what an each way return actually came to when the place terms changed. I'd just wing it and then be surprised. These days I stick my stake in before every slip, even the boring singles. The single bet calculator is the part I'm on daily — you put in the price and your stake and it shows returns straight away, fractions or decimals. Same tool covers the bigger stuff — doubles and trebles maths, lucky 15 and lucky 63, patents and yankees, honestly that's where I'd always mess it up. If you fancy a poke about, it's over at what is a super heinz in betting and it's free with no account nonsense. One thing that actually changed how I bet were the more serious extras. The probability calculator and it makes obvious what margin's baked in, and a kelly calculator — I stick to fractional kelly since full stakes are terrifying. The dutch tool is handy too when I'm splitting a race. It's not perfect mind. Its layout feels a bit basic — zero polish, which honestly I don't mind but some will. On mobile it works though the lucky 63 breakdown make you pinch and zoom. Also there's no app, it's browser only — slight shame but worth saying. Anyway. Doesn't cost anything, not plastered in adverts, works. If anyone even now works out returns on a calculator app, give it a go — saved me plenty of arguments with the bookie.

Pass this along to anyone you know dealing with similar questions, the answers here are clear, and a stop at vexaropartners adds even more useful material, this is the kind of resource that deserves to circulate widely rather than getting lost in the constant churn of new content online that buries good work daily.
