Right — been using this thing for something like six months now and it's basically bookmarked at this point, so figured I'd say something since a lad on another thread asked me the other day. Am in the UK, mainly do football and horses, nothing mad, for context.
The reason I started using it was honestly embarrassing — I never could figure out what an e/w payout actually was once you get five places instead of three. I'd just guess and then be surprised. Now stick my stake in before I place anything, even a straight one-selection punt.
The single bet calculator tool is the bit I use most — you put in the price and your stake and you get profit and total return with no faffing, fractional or decimal, doesn't matter. It also handles the fiddly ones — doubles and trebles maths, lucky 15s, patents and yankees, honestly that's where I'd always got it wrong. If you fancy a poke about, it lives at <a href=

One thing that genuinely shifted things for me is the more serious bits. There's an odds-to-probability thing and it makes obvious the overround, and a kelly staking tool — I stick to fractional kelly since full stakes are far too aggressive. The dutch tool is decent if I'm splitting a race.
Couple of gripes. Its interface is pretty plain — no polish, it's clearly function over form. On mobile it's usable although the acca grid are a squeeze. There's no app, just the site — doesn't bother me but worth saying.
Right, that's me. Free, barely any ads, works. If anyone even now works out returns on a calculator app, have a look — saves me a fair few dumb bets I'd have regretted.
