OK — been on this thing for maybe four months now and it’s stuck on my phone, so thought I’d chuck my thoughts in since someone asked me a few days back. Am in the UK, generally stick to footie and the horses, nothing mad, for context.

How I found it was genuinely pretty stupid — I never could get my head round what an e/w payout actually came to once you get five places instead of three. Basically I’d guess and then be surprised. Now punch the numbers in before I place anything, even a simple single bet.

The single bet calculator tool is the one I’m on daily — type in the price and your stake and it spits out the return instantly, either odds format. It also handles the bigger stuff — doubles and trebles maths, a lucky 15, yankees, which is where I always got it wrong. If you fancy a poke about, it lives at [url=https://single-calculator.com/bet-calculator/kelly-criterion]kelly bet calculator[/url] — free, no signup.

One thing that genuinely changed how I bet is the more serious extras. There’s an probability calculator and it makes obvious what margin’s baked in, and there’s the kelly criterion calculator — I stick to fractional kelly since full stakes are terrifying. Dutching calculator gets used a fair bit if I’m splitting a race.

Couple of gripes. Its interface is pretty plain — no frills, which honestly I don’t mind but some will. Phone-wise it’s fine although the bigger tables are a squeeze. There’s nothing on the app store, just the site — fine by me but you asked.

Anyway. Free, not plastered in adverts, does what it says. If you even now adds it up in their head, try it — saves me a fair few “wait, that’s it?” moments.
