20 Days Hard

Update – 19/11/2025: A minimal personal web app to track a 20-day challenge.
This is an early version. You might find small bugs, let me know and I’ll fix them.

Intro

I didn’t want anything fancy. All those 75 Hard apps were full of ads, subscriptions, and pointless gamification. I thought, “No, this has to be simple.” Just a way to track 20 days and stay accountable. Purely visual, minimal, and mobile-friendly.

I started this 20-day challenge myself. Once I complete it, I plan to make a bigger version for the full 75 Hard - if I manage it ;-)

This project is inspired by my previous habit widget ideas. It’s simple, lightweight, and keeps me consistent.

Set Up

1. Click 20DAYSHARD on Iphone
2. Tap the Share button (square with an arrow)
3. Select Add to Home Screen
4. Give it a name like "20DaysHard" and tap Add
5. The app now opens fullscreen like a native app

This way, you can use it just like an app, without scrolling, ads, or subscriptions.

What It Shows

• 20 circles representing 20 days
• Click a circle to see daily tasks
• Check off tasks one by one
• Circle turns green when all tasks are completed
• Progress saved automatically in localStorage

How It Works

Open the app in your browser, click a day, and check off each task. Everything saves locally. No forms, no logging, no syncing.

How to use

1. Open the app in your browser
2. Click on a day to see tasks
3. Check off each task as you complete it
4. Progress is automatically saved

Purpose

Not fancy. Not polished. Just a small tool to keep you consistent for 20 days. Completing it gives you a sense of what the next level, like 75 Hard, looks like.
