So — been using this thing for something like five months now and it's stuck on my phone, reckon I'd write something up since a lad on another thread asked me a few days back. I'm based in the UK, mainly stick to footie and the horses, a fiver here and there, for context. What got me on it was actually embarrassing — I never could figure out what an each way return would be when the place terms changed. Basically I'd eyeball it and get a shock. Now stick my stake in before every slip, even a straight one-selection punt. The single bet calculator is the bit I open most — type in your stake, the odds and you get returns straight away, either odds format. There's also the fiddly ones — doubles and trebles returns, a lucky 15, a yankee, and that's where I'd always mess it up. If you want a look, it's over at [url=https://freebet-calculator.com/bet-calculator/accumulator]acca accumulator[/url] and there's no login wall, which I appreciated. What really changed how I bet was the more serious tools. The implied probability calculator which shows you what margin's baked in, plus a kelly staking calculator — I run quarter kelly since full stakes are terrifying. Dutching calculator gets used a fair bit if I'm splitting a race. It's not perfect mind. The design is very functional, let's say — no flash, which honestly I don't mind but some will. On my phone it's usable although the acca grid need a bit of scrolling. And no proper app, it's a website and that's it — fine by me but you asked. Anyway. Free, barely any ads, works. Anyone who honestly adds it up in their head, have a look — saved me a fair few dumb bets I'd have regretted.
