What should you eat? Which movie should you watch? Who goes first? Deciva turns everyday choices into a quick, playful moment with a custom wheel and random selection tools. SEVEN WAYS TO CHOOSE • Spin the wheel: create a topic, add your options and spin to pick one. Save favorites, copy lists and use no-repeat draws when you want each option picked only once. • Light-up picker: watch the highlight move between options before it lands on a result. • Finger picker: everyone places a finger on the screen, then one participant is selected. Use it to choose who starts or who buys lunch. • Book of Answers: think of a question and reveal a random, playful phrase for a little inspiration. • Coin flip: let heads or tails settle a choice between two options. • Dice roller: roll one, two or three dice for board games and party activities. • Random number: set a minimum and maximum to draw a number within your chosen range. MAKE IT YOUR OWN Add food ideas, movie titles, weekend plans or names to a custom list. Keep favorite topics handy and look back at previous results in the available history views. Choose or create a topic → Add options → Tap to pick. Made for everyday choices and friendly games. Book of Answers phrases are random and intended for entertainment and inspiration.
