Right — been using this thing for maybe six months now and it’s stuck on my phone, so figured I’d chuck my thoughts in since a mate asked me last week. I’m in the UK, generally bet football and racing, small stakes, just so you know where I’m coming from.

How I found it was honestly pretty stupid — I never could work out what an e/w payout actually was when the place terms changed. Basically I’d wing it and get a shock. Now punch the numbers in first, every time, even the boring singles.

The single bet calculator is the bit I open most — you put in the price and your stake and it spits out returns with no faffing, fractional or decimal, doesn’t matter. There’s also the bigger stuff — doubles and trebles maths, lucky 15s, patents and yankees, honestly that’s where most people I know got it wrong. Have a go yourself, it’s here [url=https://free-bet-calc.uk/bet-calculator/accumulator]bet accumulator calculator[/url] and it’s free with no account nonsense.

What really made a difference were the nerdier bits. There’s an implied probability calculator and it makes obvious the overround, and a kelly calculator — I stick to fractional kelly since full stakes are a quick route to a dead bankroll. Dutching calculator gets used a fair bit if I’m covering two or three runners.

It’s not perfect mind. Its interface feels a bit basic — no frills, looks like it was built by someone who cares more about maths than colours. Phone-wise it’s usable although the lucky 63 breakdown need a bit of scrolling. There’s nothing on the app store, it’s a website and that’s it — slight shame but you asked.

So yeah. Costs nowt, not plastered in adverts, does the job. Anyone who even now works out returns on a calculator app, try it — saved me a fair few dumb bets I’d have regretted.
