One that will be used on a daily basis, like a tracker

sample: I have a 100 dollar budget for the entire week..each day I will break down cost to each activity
like lunch 6sgd max, transport 5 sgd fixed

and whenever I hit the budget for that activity , this will create a red mark on my list


something like that

it'll be useful for this generation

Include a feature that will calculate Savings, in a way it will motivate people to stick to their budget

or maybe a reward from your website
like 1 dollar every time the user abide by his weekly budget

so cool!

but you need to have it monetized to keep it running...think of products you can sell
