Random Generator

A Simple Tool That Solves Many Small Problems

Random Generator is a lightweight Android app I built to solve a very common problem:
“I just need a quick, fair random result — without ads everywhere or unnecessary complexity.”

Instead of making separate apps for numbers, lists, colors, or coin flips, I designed one fast, offline-first app that does all of it cleanly.

What the App Does

Random Generator includes multiple small tools, each focused on doing one thing well:

🔢 Numbers

Generate random numbers within any range.

Supports large ranges
Optional unique numbers
Sorting (ascending / descending)
Higher limits available via Pro unlock

Useful for contests, simulations, testing, or quick decisions.

📝 Lists

Paste a list of items and let the app randomly pick from it.

Pick 1, many, or all
Optional unique picks
Shuffle support
Save lists & view pick history (Pro)

Great for names, tasks, teams, or everyday decisions.

🔤 Letters

Generate random letters with fine control.

Uppercase / lowercase
Vowels, consonants, or both
Unique letters
Presets like Vowels, Scrabble, Password (Pro)

Helpful for word games, learning, or password ideas.

🎨 Colors

Create random color palettes instantly.

Copy hex codes
View palette history (Pro)
Clean visual previews

Designed for designers, developers, and quick inspiration.

🪙 Coin Flip

A simple, realistic coin flip.

Smooth animation
Haptic feedback
Flip history (Pro)
Premium coin designs (Pro)

Perfect for fast yes/no decisions.

Design Philosophy

This app follows a few clear principles:

Fast & offline-first — works instantly, no accounts
No forced ads — ads are optional via rewarded unlock
One-time Pro access — watch a short ad to unlock Pro for 30 minutes
Clear value — Pro features are explained per screen, not vague

I intentionally avoided subscriptions and dark patterns.

Pro Access (Optional)

Pro features can be unlocked temporarily by watching a rewarded ad.
This gives access to:

Higher limits (e.g. more numbers)
History & saved data
Advanced presets
No banner ads

No payment. No pressure.

Tech Stack (For Fellow Developers)

Kotlin + Jetpack Compose
MVVM architecture
StateFlow
Google Play In-App Review API
Google AdMob (banner + rewarded)
DataStore for persistence
