OK — been on this thing for about five months now and it's stuck on my phone, reckon I'd say something since someone asked me the other day. Am based in the UK, mostly stick to footie and the horses, small stakes, so take it how you like. How I found it was honestly embarrassing — I could never work out what an ew payout actually came to when the place terms changed. Basically I'd eyeball it and moan when the payout landed. Now I stick my stake in first, every time, even the boring singles. Their single bet calculator is the part I open most — type in stake and odds and it spits out returns straight away, either odds format. Same tool covers the fiddly ones — doubles and trebles maths, lucky 15 and lucky 63, patents and yankees, and that's where most people I know mess it up. If you fancy a poke about, it lives at free lucky 15 bet calculator — free, no signup. What really changed how I bet was the nerdier bits. They've got an odds-to-probability converter that shows how much the bookie's taking, and a kelly staking calculator — I stick to fractional kelly because full kelly is terrifying. The dutching one is decent when I'm covering two or three runners. It's not perfect mind. Its interface feels a bit basic — no frills, it's clearly function over form. On mobile it's usable although the bigger tables are a squeeze. There's no proper app, just the site — fine by me but worth saying. Right, that's me. Costs nowt, barely any ads, does what it says. If anyone still does the maths on paper, try it — saves me a fair few "wait, that's it?" moments.

Solid quality, the kind of work that holds up to a careful read rather than a quick skim, and a quick look at nevirounion kept that standard going strong, content that rewards attention rather than punishing it is something I appreciate more and more these days online across nearly every topic I follow.

So — been on this thing for maybe a few months now and I keep coming back, reckon I'd say something since a lad on another thread asked me the other day. I'm UK based, generally do football and horses, a fiver here and there, so take it how you like. The reason I started using it was actually pretty stupid — I could never work out what an each way return actually came to once you get five places instead of three. Basically I'd wing it and then be surprised. Now stick my stake in before every slip, even the boring singles. The single bet calculator is the one I'm on daily — you put in stake and odds and it spits out profit and total return instantly, fractional or decimal, doesn't matter. It also handles the fiddly ones — acca and treble returns, lucky 15s, patents and yankees, honestly that's where most people I know got it wrong. If you want a look, it's here free super heinz with singles bet calculator — free, no signup. One thing that really shifted things for me was the geekier extras. The implied probability thing which shows you how much the bookie's taking, and there's the kelly criterion tool — I stick to fractional kelly since full stakes are far too aggressive. The dutch tool gets used a fair bit for when I'm splitting a race. Couple of gripes. Its interface is very functional, let's say — no polish, which honestly I don't mind but some will. On my phone it works although the bigger tables make you pinch and zoom. Also there's nothing on the app store, it's browser only — slight shame just flagging it. So yeah. Doesn't cost anything, not plastered in adverts, works. If anyone even now works out returns on a calculator app, have a look — saved me a fair few dumb bets I'd have regretted.
