Decide quickly when you are unsure. FLIP CHOICE is a simple app that lets you spin a coin with a tap and make a result by stopping it at the right moment. With 2 coins, it works like a classic heads-or-tails flip. With 3 to 10 coins, it becomes a fun random picker for multiple choices. It works well for small daily decisions, family moments, classroom activities, party games, or any situation where you want a quick and satisfying way to choose. This version now supports up to 10 coins. You can also assign your own photos to each coin. Use a photo you take with the camera or choose an image from your photo library to create original custom coins. Images can be adjusted in a circular editor with drag, zoom, and positioning controls, so it is easy to make them look right. The experience is intentionally simple. Tap the coin to start, then tap again to stop. The motion and stopping feel are designed to be smooth and satisfying. Simple at first glance, but more personal than an ordinary coin flip. Use your own custom coins to make everyday choices more fun.

The clearest difference is ads: FlipChoice at none against Shake Judge's shown. FlipChoice also leads on update cadence (fortnightly vs every 5 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
