The First Thing it Does

Seattle Rex

When I open the app, is ask me to rate. Well, okay, if you really want me too ... Based on what I've seen so far, all the app does is as you to rate it. That's may only experience with it. I'm really underwhelmed so far. Launched the app, I've spent 2 minutes rating it. Pretty lousy experience if you ask me. Alright, there you go. I did what you asked. I rated. Can I use me time for me now? BTW, my landlord just raised my rent. Can you call her and ask her to lower it back? See, you're not the only one that needs something, I just can't use your device to pop message up asking you for help, though. Seems kinda one-sided.



Please make it work for the apple watch too! It would be really cool!

I've been waiting for this app for so long and they finally did it! Great job! Real randomizer that uses some sort of wind speed measurements to find out a random number so it's more trustworthy than most of other random number generators that work because some simple algorithms! Deff to have you you ever used their website!

Needs history for random list results


Purchased this app not knowing how it would function since there is no trial, found out that there is no way to keep track of generated random lists like the coin toss. Also, there is no “shake” to randomize feature. Was trying to use this app to generate a set of 24 draws on an ESP app using the random list (Green/Yellow/Red/Blue) using the first (1.) result as the draw color, however, since there is no history, its very tedious and time consuming. Will be contacting app store regarding refund.
