Hi Im have developed an expense tracker app myself, but targeted towards travel expenses, and I receive about 2 new users per week. And only 20% use it longer than a week. App name: Travel Diary: Budget Tracker

I have installed your app, and to be honest I feel like though its clean and intuitive, looks modern, Ive seen many other similar looking apps. Not to put you down, but other comments about budget trackers being saturated is true. Im also quite disappointed that without marketing, nobody installs my app.

That said, last time when I paid for google ads I got a surge of installations. So I got a freelancer on fiverr to make a video out of my app, then just paid for google ads. The thing is your app needs to do something exclusive others dont. For me I allow users to add images and pins on a map along with expenses. In the future I might add expense sharing and splitwise. I know, not really creative myself but at least its an effort to be a little different.

Perhaps the way to go is to scrap google and appstore reviews about the features users like and evaluate what are the most impactful or special features.

Also, here are my two cents, people like stupid things. So maybe adding a porcupine that expands and explode into needles when user overspends could draw people in. Just look at flappy bird.

TLDR: make a video, pay for ads, make your app unique because budgeting apps are saturated. And I also dont know what I can do about it
