I got tired of apps trying to monetize my attention.

Notifications, ads, endless feeds — it never stops.

So I decided to build an Android app with zero backend.

I'm a Japanese developer, and English isn't my first language, so I used AI to help write this article.

How many productivity apps have you downloaded, only to be greeted by a mandatory registration screen, bloated interface, pop-up ads, or a constant push for a premium cloud subscription?

Something felt missing from every app I tried.

I wanted the simplicity of a paper notebook combined with the convenience of a smartphone — a tool where my thoughts and tasks stay private, on my own device, without constant distraction.

So I built ZEROLOG — a fully offline, minimalist daily planner for Android.

In this article, I’ll share:

The design philosophy

The tech stack

The challenges of building a 100% offline app

And how I passed Google Play’s 20-tester requirement

The Philosophy: "Analog-Inspired" Digital Minimalism

ZEROLOG is inspired by pen-and-paper planning.

No loading

No accounts

No tracking

No notifications

Just open the app, write your day, and move on.

The Tech Stack

React 19

Vite 7

Tailwind CSS v4

Capacitor 8

Why Capacitor?

Capacitor lets me build with React while still accessing native features like:

Haptics (vibration feedback)

Local filesystem

Native notifications
