Dual up down timer vs Screenseer

With a simple user interface users can quickly setup and use a heat up and cool down styled timer. The screen flashs black at the end of the heat up portion and white at the end of the cool down portion.

Do you have a modern phone or tablet that lies idle when you're at home or work? Or perhaps you have an old device gathering dust in a drawer? Give them a new purpose with Screenseer—the endlessly-on, fully-customizable clock app you never knew you needed (but now won’t live without). What it does: Turns any screen into a stylish clock—because time waits for no one, but your screen definitely can. Runs 24/7 so your device finally has something productive to do (unlike you during meetings). Works well on modern devices and lots of "vintage" models. Why it’s awesome: Comes with multiple clock faces—analog, digital, maybe even existential (we’re working on it). Customize colors, fonts, and backgrounds like a true design diva. Use solid colors, your favorite static image, or even a moody video background. Use Screenseer to: Add flair to your desk, nightstand, kitchen counter, or shrine of obsolete gadgets. Give new life to your old hardware instead of tossing it into the eternal drawer of tech shame. So go ahead, install Screenseer. It’s free, it’s fabulous, and it makes your screen look like it actually belongs in 2025. It's meant to be run on a device that it permanently powered and it's a perfect use for an older phone or tablet! Current clock channels: Basic clock - It's anything but basic!
