Sol Calendar marks the first release from Tentai Technology — a journey that starts here, with a simple calendar app, but reaches toward something far greater.
We believe in building software that respects users. No tracking, no ads, no data harvesting. Just pure, functional beauty. Sol Calendar is free forever, works offline, and puts you in control.
This is our first step. A small release, but crafted with care and attention to detail. Every feature, every pixel, every interaction has been thoughtfully designed.
"The best way to predict the future is to build it."— The Tentai Vision
More is coming. Much more. This calendar is just the opening chapter of a larger story. Stay tuned for what's next.
