Right — have been messing about with this thing for something like a few months now and it's stuck on my phone, so thought I'd write something up since a lad on another thread asked me a few days back. Am based in the UK, mostly stick to footie and the horses, small stakes, for context.

The reason I started using it was actually a bit daft — I could never get my head round what an each way payout actually came to when the place terms changed. I'd just eyeball it and get a shock. Now stick my stake in first, every time, even the boring singles.

Their single bet calculator tool is the bit I use most — you put in your stake, the odds and you get returns with no faffing, fractional or decimal, doesn't matter. It also handles the multiples — trebles returns, lucky 15 and lucky 63, patents and yankees, and that's where most people I know lose track. Have a go yourself, it lives at <a href=https://single-calculator.com/bet-calculator/lucky-63>how to work out a lucky 63</a> and it's free with no account nonsense.

The thing that genuinely changed how I bet were the geekier extras. They've got an probability converter and it makes obvious how much the bookie's taking, plus a kelly staking tool — I stick to fractional kelly because full kelly is terrifying. Dutching calculator is handy too when I'm splitting a race.

Not all sunshine though. The interface looks a bit basic — no flash, looks like it was built by someone who cares more about maths than colours. Phone-wise it's fine although the acca grid make you pinch and zoom. And nothing on the app store, just the site — slight shame just flagging it.

Anyway. Costs nowt, not plastered in adverts, does the job. If anyone even now does the maths on paper, try it — it's saved me plenty of dumb bets I'd have regretted.
