What is Eatshimo?

Eatshimo is a personal project I built because I could not find a calorie tracking app that fit my needs.

Most existing calorie apps are either:

Ad-heavy
Locked behind subscriptions
Overcomplicated with unnecessary features
Rely on inaccurate community food databases that you cannot edit

So I decided to build something simpler.

This was basically a “fine, I’ll do it myself” project.

I wanted:

A clean calorie tracker
Full control over my data
No ads or paywalls
Offline-first functionality
Simple and fast tracking
Be able to edit food libraries without creating new food or relying on community databases.

Developing Eatshimo has also been a great learning experience, especially with modern development tools and AI-assisted coding making development faster and more accessible.

I plan to continue building more open-source, privacy-focused tools like this in the future.
