The is good in ways, straight forward to use, however even after purchasing pro version it would let me set up notifications, option for this is even greyed out completely in phones app settings so I'm assuming it needs an update that it likely won't get?...as I'm not the first person to email they have ignored. can only recommend the free version as pro features are janky at best right now, save your £2.99, one of payments are nice but only for something that works as advertised

I've looked at several of these intermittent fasting apps and this is easily the best. It allows you to set an alert for the start time, and then you just press a button after the last meal of the day and then before the first meal. It logs your times and you can enter your weight as well. It doesn't ask for unnecessary information like details of what you've been eating. Also only £2.99 one off. All the other apps are over complicated inflexible and expensive moneyspinners for their operators

I love this app. After trying it out for free found it easy to use, to alter the fasting times and add weight, etc - unlike the first two I tried - so I paid for the Pro version. Very happy with it. Update: still love the App except the fact that the weight loss change doesn't work. Having lost 15lbs and logged each loss it still says I've lost an 8lb change and does not veer from that figure. 20th Nov 2020 -- Still using and loving the app. Lost 24lbs doing 16:8 since 12 July.
