Projects
Apps and experiments I've built and published
Mobile Apps
Math Wheel
A family math game: spin the wheel, solve, and level up. Practice or race the clock in Addition, Subtraction, Multiplication, Division, or Mix.
- Challenge: Easy, Medium, and Hard — keypad, multiple choice, or draw.
- Reward: Unlock avatars, music, streaks, and a printable certificate (Easy + Medium; Hard is bonus).
- Play: English, Spanish, Portuguese, and French, with optional Apple/Google backup.
Guess Duel
A fast number duel that turns logic into a lively game with friends — hide your secret, guess theirs, and win in fewer tries.
Three ways to play: Challenge a friend with a cross-platform code, duel the Computer anytime, or crack today’s Daily Challenge.
Built for fun: Reactive celebrations, meme moments, and sound effects keep every round engaging.
Encryptor
A browser-based utility I built to encrypt and decrypt HTML source — handy for protecting snippets during experiments or quick deploys.
Quick workflow: Paste code, encrypt, copy the output. Decrypt anytime to edit again.
Runs locally: Everything happens in the browser — no server required.
Websites
Sites and landing pages I’ve built over the years — including the product pages on this domain for each app I release.
Procolin.com itself is part of the portfolio: one place for project pages, privacy policies, and App Store / Google Play links.
