RandN
Read full descriptionHide full description
RandN is a small, focused iPhone app for picking a random number in a selected range. Why it is useful: - No ads, banners, tracking, or forced videos. - Choose From and To with smooth wheel pickers instead of typing numbers. - Set a higher maximum in Settings when you need larger ranges. - The result updates automatically when either bound changes. - RandN remembers your selected range and maximum between sessions. - A fresh random result is generated each time the app launches. RandN supports positive integer ranges from 1 up to a configurable maximum of 100. The experience stays deliberately simple: open the app, choose the range, get the number.
