A habit tracker app combined with a top Alarm app might be the perfect combination to start with the long-pending goal. Habit Tracker is an all-in-one goal tracker app for Android where you set customized goals like today will be a successful day when I eat apples, (at least/exactly/not more than) two times a day.
Apart from that, this great app for 2019 features detailed reports in the form of graphs and even presents motivation quotes to refuel when you are feeling blue. You can also participate in the in-app forums to interact with people having similar goals. Believe it or not, this is the best Google app that you should add to your fitness regime.
