Why not try My Fitness Pal? At least it's free! I lost almost 4 stone using it (and I took up running from scratch think C25K - but it's 80% what we eat, so that's just an incidental).
I'm now 3 years on, and my 'new' way of eating is just normal now. I know what looks right because of all the times I weighed stuff. I know what recipes work, and I don't snack. Ever.
I haven't been able to run as much the last 6 months, and I had the stress of a parent dying, not to mention the over-eating of Christmas/the temptation of winter 'fodder' eating, but here I am, just unpacking my summer clothes from last year (when I bought size 12s for the first time in my 52 years!) and they all still fit. I haven't done anything other than 'eat normally', but importantly it's the 'new normal' of eating well, but eating within the limits of what my body actually needs.
I tried loads of 'diets' before, including 5:2 (not compatible with a family you're the sole cook for) but I just made sure no main meal was over 600 cals for me, and gave everyone else the same main, but with extra carbs if they wanted them, and loads (and I mean loads!) of veg and salad.
But ultimately, do what works for you. You need to feel great in your own skin, and however you get there never lose that feeling - then you'll find it easier to stay there! I'm sure that's more than half the battle!
Ramping up the running again now (I like to do the Race for LIfe every year) but that's more for my mental well-being than my weight.
Good luck!! You can do it!
