Practical software built for everyday use.
We build and operate focused web tools and business software used for everyday financial planning, learning, public discussion, and field service operations.
Each product is designed to stay fast, straightforward, and easy to use without unnecessary clutter.
Independent and focused on
useful software.
Celestiq Insights is an independent software company based in Bengaluru, India. We create and maintain our own digital platforms and business tools rather than doing client outsourcing work.
Staying small and self-funded lets us focus directly on product quality, keep our public web tools free through standard advertising, and continuously improve Service Saint for small businesses.
"Our goal is simple: build straightforward software that helps people calculate decisions, test their knowledge, share views, and manage daily business work cleanly."
Simple tools that
respect your time.
Every platform we run is shaped around three practical standards for the people who use it every day.
Clear Interfaces
Pages load quickly and stay organized around the task at hand, whether you are running a loan calculation or preparing a customer quote.
Practical Coverage
We focus on everyday tasks across financial and health calculators, quizzes and brain games, multilingual polls, and field-service billing.
Responsible Data Handling
Free calculators work without signups, accounts and cloud backups stay under your control, and we never sell personal or business data to brokers.
Four active products
