Keep Screen On & Dimmer Screen vs RPN Deck

Keep Screen On & Dimmer Screen brightness will help you do two those things in zero tap! Just open the app, your phone screen will be on forever and your phone screen brightness will down to zero too! Lower your phone screen brightness is an impressive feature of this app because most of us want to keep screen on and lower phone screen brightness together. Timeout to turn off is also a good feature! This app is useful when you want to keep screen on while uploading video to YouTube, downloading big file or for developer who want to keep screen on! Thank you!

RPN Deck is a reverse Polish calculator built for speed — and for fixing mistakes without starting over. EVERY NUMBER STAYS EDITABLE On most calculators one wrong digit means clearing the lot and typing it again. Here every value stays on screen. Tap a row to correct it in place. Swipe a row away to delete it. Undo steps back through anything you did. RPN, PROPERLY Type a value, press ENTER, type the next one. No parentheses. No equals key. No expression to hold in your head and get wrong three terms later. The stack is unlimited and every level of it stays visible. FAST Four functions and a percent key. TOTAL folds the whole stack into one number in a single press. Nothing is buried in a menu, because there are no menus. THE FULL DECK — a one-time in-app purchase Three ways in, one unlock. The Tape prints every keystroke like a receipt — each entry, each operation, each total — and shares as an image, text, or PDF. Scan points the camera at a receipt so you tap printed amounts straight onto the stack. Voice lets you speak numbers and they land where you'd type them. Family Sharing is supported, so one purchase covers your family group. SIMPLE ON PURPOSE No scientific functions. One surface, and everything on it does something. PRIVATE BY DEFAULT No account. No sign-in. No analytics, no tracking, no advertising. Nothing leaves your phone unless you share it yourself. iPhone, portrait, English.
