Hey Product Hunt community! 👋
I'm super excited to share Flash Calculator with you all. I've been working on it for a while to address the pain points of slow, bloated, and popup-heavy calculator websites that are difficult to use on mobile devices.
What makes Flash Calculator special?
Websites built with Next.js are lightning-fast thanks to their static edge, so you can say goodbye to slow loading times.
You'll also love the mobile- and PWA-friendly interface that looks great on all screen sizes, including when you're working offline.
There's a variety of calculators at your disposal, ranging from scientific computations to loan EMIs, fitness, and unit conversion tools - the list goes on!
Finally, all calculations in Flash Calculator are performed in your browser for ultimate privacy.
I'm eager to hear what you think about Flash Calculator, receive any feedback, and learn which calculators you'd like to see in the future.
