UpUpFrog

Read full description

UpUpFrog is the slack-off companion that turns your monthly salary into a live earnings counter — making your paycheck something you can watch tick up every single second. The app opens in Demo Mode: your earnings counter keeps ticking around the clock — during lunch, your commute, even while you sleep — so you can actually watch your "passive income" add up. Prefer your real schedule? Switch to Work Mode with one tap, and it only counts time between clock-in and clock-out. Set your monthly income, work hours, workdays, lunch break, and currency once, then watch today's earnings update in real time. Instead of relying on simple accumulation, UpUpFrog recalculates from the current time, so your numbers stay accurate after a break, after lunch, or after reopening the app later. What you can do with UpUpFrog: - Watch today's earnings tick up every 0.1 second - Switch between Demo Mode (all-day passive income) and Work Mode - Convert coffee, milk tea, movie tickets, and custom prices into work time - Use multiple currencies with online rates and built-in fallback support - Keep today's progress on your Home Screen with a widget UpUpFrog is built for motivation, self-tracking, slack-off fun, and salary comparisons. It does not handle payments, transfers, or any real financial transactions — all numbers are estimates based on your own settings.
