OK — been using this thing for about a few months now and it's stuck on my phone, so thought I'd chuck my thoughts in since a mate asked me the other day. I'm UK based, mainly do football and horses, a fiver here and there, for context.
The reason I started using it was genuinely embarrassing — I couldn't ever get my head round what an ew payout would be when the place terms changed. I'd just wing it and moan when the payout landed. Now type the odds in before I place anything, even a straight one-selection punt.
The single bet calculator is the one I use most — type in stake and odds and it shows the return instantly, fractional or decimal, doesn't matter. There's also the fiddly ones — doubles and trebles maths, lucky 15 and lucky 63, a yankee, honestly that's where most people I know mess it up. Have a go yourself, it lives at betting accumulator calculator and there's no login wall, which I appreciated.
One thing that really made a difference was the more serious bits. There's an implied probability converter that shows how much the bookie's taking, and a kelly tool — I run quarter kelly as the full version is far too aggressive. The dutching one gets used a fair bit for when I'm spreading across selections.
Couple of gripes. Its design feels pretty plain — not much frills, it's clearly function over form. On mobile it's fine but the lucky 63 breakdown are a squeeze. There's nothing on the app store, just the site — slight shame but you asked.
Right, that's me. Free, no ads shoved in your face, does what it says. If you still works out returns on a calculator app, try it — it's saved me plenty of arguments with the bookie.
