Simple Coin Flip (Phone+Wear)
On your phone: Simply tap the question mark or shake and view the result. Tap the coin or shake to spin the coin again.
On your watch: Say "Ok, Google. Start Coin Flip." Tap the question mark to spin the coin.
Spinning coin animation, sound, text, vibration, shake-to-flip and coin type are all configurable via the Settings menu. Verify the flip algorithm is truly random by running the built-in Diagnostic Test and flipping the coin 100,000 times (or more) while watching the results in real-time. (Sorry, no cheating!)

WHO CARRY COINS ANYMORE? I think this was the thinking behind this app. It does a very good job of flipping a coin and showing you the results. Not quite a pari-mutuel result ... but, who cares? If you've got to make a true/false decision, this will help. There is some simple stuff the author could have added to make this worth 5 stars: Make the coin say true/false, or yes/no or buy/save. And, I would have liked a way to keep the coin spinning until I decided to stop it. I teach bus driving, and when I have two students, I use this app to help decide who's driving first. Sometimes I have up to four students. If this app would have permitted me to add the first names of the students I would have paid for the app.
Simple, add free, coin flip app with a satisfying vibration on flip. Flick your phone and watch the coin go. Good for making quick, non consequential decisions. Comes with diagnostic test for peace of mind regarding bias. Only one coin unless you purchase the 99 cent coin bundle, which i am considering 😆
Please add a side-flip feature. Sometimes coins land on side, and it would be fun to be able to enable that here. I think the odds of a side landing are abysmal low tho.
Does what it says with no invasive permissions or ads. Bought the 99 cent pro version five seconds later just to say thanks. Also Pro comes with a bunch of coins to choose from!
Does exactly what it should. And comes with a Mario sound effect for each flip. Exactly what I needed it's great
Thank you for making an app that does what it's supposed to without taking weird private information it has no need to access. Best coin flip app, hands down.
Exactly what it says on the tin. No ads, no gimmicks, just a good coin flipper.
Good app. However, there's only one coin. You can have the option to buy more coins, but I haven't found how to buy them.
DON'T INSTALL THIS. I just got a call that reported this app as a security breach and we had to uninstall thia immediately. UNINSTALL FROM YOUR PHONE IF YOU HAVE THIS ASAP.
It would be great if I could put in a string of results and a bot tries to predict the next result.
No ads no permissions. All apps should be like this. Thanks.
Flips a coin. No ads or permissions. Hope it doesn't update.
My friends and I don't even use real coins anymore. Love this app, you've got to try it!
Got three Breaker of Armies via Mirror March due to this wonderful app. Worth every penny!
Awesome. The statistics and diagnostic are extremely useful.
bro i love this app. im a big dumb baby whos brain malfuntions when i have to make a decision and i just flip this little coin and BOOM choice made babey
Perfect! Coin flip and nothing else.
How does it come, that my diagnostic has the exact same result, is in the picture of the play store? (only took a little longer)
Would be great if there was a British coin
Phenomenal app, no adds, use it constantly
I like that I can turn the sound off
I like it because it shows stats
pretty good and useful
does exactly what it says on the tin
Heads 60-80%
DO YOU WANT TO FLIP A COIN!?
Try Best for u
Wonderful app! My family and I are terrible at flipping coins, so we use this app for board and card games. True to its name, it really is simple and truly random. I made some Pokemon themed coins to customize it for our game. Thank you, this app truly is a gem.
The whole damn thing is rigged man, game over man. You tap it to get tails and then shake it to get heads
I've been using this app for years now. Maybe a 100,000 flips so far. It's simple, it's tiny, it's reliable. All you need in coin flip app. I wish we could change the faces a lot more but overall still loved it. But I get that that would add more bulk to the app.
