What is a web app?
A web app is software that runs in your browser instead of being installed on your device. If you've used Google Docs, a banking dashboard, or an online calculator, you've used a web app. You open a link and start using it — nothing to download, nothing to update.
That's what makes them powerful: one link works on any phone or computer, updates reach everyone the moment we ship them, and well-built tools can do their work entirely on your device — so your data never has to leave your browser.
Nothing to install
Open a link and it just works — no downloads, no app store, no updates to chase.
Any device
One app runs on phone, tablet, and desktop from the same URL.
Always current
We ship an update and everyone has it instantly — no version left behind.
Private by default
Tools like ShashaTools run in your browser — your numbers never leave your device.
OUR APPROACH
Free tools, honest products.
We build genuinely useful tools and give a lot of them away. ShashaTools is a growing library of 96+ calculators — finance, health, business, and more — free, instant, and with no sign-up. Other products, like Stelt, are priced fairly for what they do.
Free software has to pay for itself somehow — and the usual answer is stuffing it with third-party ad networks. We'd rather not. Instead of renting our users' attention to Google AdSense, we use our free tools to introduce people to our own products — ATMOS, Stelt, and what comes next. Cleaner for you, and it funds the next free tool.
How the free tools pay for themselves
Product revenue funds the next free tool — no third-party ad networks required.
