So — have been messing about with this thing for something like six months now and it's basically bookmarked at this point, so figured I'd write something up since a mate asked me a few days back. Am in the UK, mostly bet football and racing, nothing mad, so take it how you like.

How I found it was genuinely embarrassing — I never could figure out what an ew return actually came to with 1/5 odds a place. I used to just eyeball it and then be surprised. Now type the odds in first, every time, even a simple single bet.

Their single bet calculator tool is the bit I use most — you drop in the price and your stake and it shows profit and total return instantly, either odds format. Same tool covers the bigger stuff — acca and treble maths, lucky 15 and lucky 63, yankees, which is where most people I know lose track. Have a go yourself, it's over at <a href=https://freebet-calculator.com/bet-calculator/matched-betting>exchange bet calculator</a> and there's no login wall, which I appreciated.

One thing that really made a difference is the nerdier extras. They've got an implied probability thing and it makes obvious the overround, and there's the kelly staking calculator — I use half kelly since full stakes are far too aggressive. Dutching calculator gets used a fair bit when I'm covering two or three runners.

Not all sunshine though. Its interface feels pretty plain — zero flash, it's clearly function over form. Phone-wise it's usable but the acca grid need a bit of scrolling. There's no app, just the site — doesn't bother me but you asked.

So yeah. Free, no ads shoved in your face, does what it says. If you even now adds it up in their head, give it a go — saved me a fair few "wait, that's it?" moments.
