This app cant keep the fasting records more than 3 to 4 days time. It crashed and started keeping track again. Only the weight you can track continuesly. I don't have any idea about paid version because I don't want to pay just to keep record of my daily foods routines. I'm okay whatever the free one I'm getting now. It helped to start monitoring my food habits and stay on a disciplined diet habits. So for that I gave 2 and for not keeping the full record on free version it got ZERO. Thanks.
