Perfect Circle
Perfect Circle is a mobile-first drawing challenge. Tap Enter, then draw one continuous loop around a glowing dot with your finger. The app measures how round your loop is in real time and shows a live accuracy percentage, with the pen trail glowing from red to green as your circle improves and sparks trailing your fingertip. Releasing after a full loop triggers a ring flash and reveals your final score, a rank line, and your best score. A result card shows your loop against the perfect ring so you can see exactly where you drifted. Share your score card to the community or replay instantly. Fully touch-based, portrait-only, with an English and Chinese language toggle.
