PrettyRandom vs CyberTracker

A random number, as fast as a tap. Set the lowest and highest number you want. Choose whether those two ends count. Then get a number in one of three ways. THREE WAYS TO GET A NUMBER • Tap the circle • Shake your phone • Set a timer and let numbers arrive on their own SET THE RANGE Tap either end to change it. Any two whole numbers work, including negative ones. Mark an end as inclusive to allow it, or exclusive to leave it out. That way 0 to 10 can mean 0 through 10, or 1 through 9. GOOD FOR • Deciding who goes first • Picking a chore, a seat, or a place to eat • Rolling dice when the dice are lost • Drawing a winner from a numbered list • Showing a child how ranges and chance work NOTHING LEAVES YOUR PHONE PrettyRandom makes no network calls at all. There are no ads, no analytics, no accounts, and no tracking. No data is collected, because there is nowhere for it to go. There is no sign-up and nothing to learn. Open it and you have a number. Requires iOS 17 or later.

CyberTracker is software from a South African non-profit company, CyberTracker Conservation, that develops handheld data capture solutions. The software was first developed as a way to allow illiterate animal trackers to communicate their environmental observations. A prototype was used in 2002 to record details of animals killed in an outbreak of ebola. It has since evolved to become a general purpose data capture and visualization system. However, it retains the ability to be used by illiterate and low-literate users. CyberTracker's primary user base is wildlife biologists, conservationists and disaster relief workers.
