My first ever shipped iOS app. A native sticky notes app built for iPhone that replaces physical sticky notes with colorful, digital ones.

Project Overview
Posty started from a personal problem. I love sticky notes. I use them for quick thoughts, to-dos, ideas, anything that needs to be written down fast. The issue was the paper waste. Every week I was throwing away a pile of them and it started to bother me. So I decided to build a solution myself.
Posty is a native iOS app that replicates the feeling of writing on sticky notes. Simple, quick, and out of your way. No accounts, no subscriptions. Just notes.
Features Built
The app ships with three types of notes and a few thoughtful extras:
- Text Notes: For ideas, reminders, and quick thoughts.
- Todo Notes: Simple checklists with checkable items.
- Drawing Notes: Sketches and doodles with a built-in canvas.
- Highlight & Widgets: Mark one saved note as your highlight and pin it to your Home Screen or Lock Screen widget.
- Live Activity Support: Track your todo progress from the Dynamic Island and Lock Screen without opening the app.
- Curl to Save: A custom corner-curl gesture to save a note, designed to mimic the feel of folding a real sticky note.
Technical Stack
- Swift & SwiftUI for the entire app
- WidgetKit for Home Screen and Lock Screen widgets
- ActivityKit for Live Activity support
- SwiftData for local persistence
This was my first time going through the full cycle of designing, building, and actually shipping something to the App Store. Every step, from setting up the project to submitting for review, was new territory. I ran into a lot of walls but working through each one taught me more than any course ever could.
Shipping Posty is something I'm genuinely proud of. It's a small app, but it's a real one, and it's out there for people to download. That feeling is hard to beat.
