It's Been This Long

Every day counts — see exactly how far you have come.

What is It's Been This Long?

It's Been This Long is a beautifully designed milestone and streak tracker for iPhone and Apple Watch. Whether you are marking a personal achievement or building a new habit, it gives you a clear, motivating view of how much time has passed since any moment that matters to you.

The problem it solves

It can be hard to stay motivated when you cannot see your progress at a glance. It's Been This Long fixes that by showing you precisely how many days have passed since any event or action — turning invisible progress into a visible source of pride.

Key Features

Designed to be useful, focused, and easy to understand.

Milestone Tracking

Add any meaningful date and instantly see a live count of exactly how many days have passed.

Streak Awareness

Watch your streaks grow day by day, giving you a powerful reason to keep going.

Apple Watch Support

Check your progress right from your wrist without ever opening your phone.

Beautiful, Clean Design

A modern interface that keeps your milestones front and center without any clutter.

Flexible Use Cases

Track sobriety, habits, anniversaries, or any personal achievement — all in one place.

Who this app is for

Perfect for anyone working toward sobriety, tracking anniversaries, building healthier habits, or celebrating personal milestones. If a date matters to you, this app helps you honor it.

Why I built it

I wanted something like a reminder app, but one that flipped the question — instead of telling you what to do next, it tells you how long you have already stayed the course. Knowing it has been 47 days since your last cigarette feels very different from a simple to-do notification.
