OK — been on this thing for about six months now and it's basically bookmarked at this point, so figured I'd write something up since someone asked me the other day. Am based in the UK, mostly stick to footie and the horses, a fiver here and there, just so you know where I'm coming from. What got me on it was honestly embarrassing — I never could figure out what an e/w return actually came to with 1/5 odds a place. I used to just wing it and then be surprised. These days I stick my stake in first, every time, even a straight one-selection punt. Their single bet calculator is the bit I open most — type in the price and your stake and it spits out returns with no faffing, fractional or decimal, doesn't matter. Same tool covers the bigger stuff — doubles and trebles maths, a lucky 15, a yankee, and that's where most people I know got it wrong. If you want a look, it's here [url=https://singlebettingcalculator.uk/bet-calculator/each-way]each way bet calculator free[/url] — free, no signup. One thing that really made a difference is the nerdier extras. The odds-to-probability calculator which shows you how much the bookie's taking, and there's the kelly calculator — I stick to fractional kelly as the full version is far too aggressive. The dutching one is decent when I'm splitting a race. Couple of gripes. Its interface looks very functional, let's say — no polish, looks like it was built by someone who cares more about maths than colours. Phone-wise it's usable though the lucky 63 breakdown are a squeeze. Also there's nothing on the app store, just the site — fine by me but you asked. Anyway. Free, not plastered in adverts, works. Anyone who even now adds it up in their head, have a look — saves me a fair few dumb bets I'd have regretted.
