Right — have been messing about with this thing for maybe four months now and I keep coming back, reckon I'd say something since a mate asked me last week. Am based in the UK, mostly bet football and racing, a fiver here and there, just so you know where I'm coming from.
 
The reason I started using it was honestly embarrassing — I never could work out what an each way payout actually was when the place terms changed. Basically I'd guess and get a shock. Now I stick my stake in before I place anything, even a simple single bet.
 
Their single bet calculator is the bit I open most — you drop in the price and your stake and it shows the return with no faffing, fractions or decimals. Same tool covers the fiddly ones — trebles maths, lucky 15s, yankees, honestly that's where most people I know got it wrong. If you fancy a poke about, it's over at <a href=https://freebet-calculator.com/bet-calculator/implied-probability>how to calculate implied probability with fractional odds</a> — free, no signup.
 
The thing that genuinely changed how I bet were the nerdier tools. They've got an probability calculator that shows the overround, and a kelly tool — I run quarter kelly because full kelly is terrifying. Dutching calculator is handy too if I'm spreading across selections.
 
Not all sunshine though. The interface is very functional, let's say — not much frills, it's clearly function over form. Phone-wise it's fine though the acca grid make you pinch and zoom. There's no proper app, it's browser only — slight shame just flagging it.
 
Right, that's me. Free, barely any ads, does the job. Anyone who honestly adds it up in their head, have a look — saves me a load of dumb bets I'd have regretted.
