About SPQR Developers
Building smart, reliable software that solves real-world problems.
Who We Are
A small but mighty independent development studio
SPQR Developers was founded on a simple belief:
software should make life easier — not more complicated.
We create thoughtful, practical, and beautifully engineered apps that help people
work smarter, stay organized, and enjoy their hobbies.
Our name, inspired by the Roman “Senātus Populusque Rōmānus,” represents
craftsmanship, durability, and a commitment to building things meant to last.
What We Build
Purpose-built apps designed with everyday users in mind
GrowZone
A smart gardening companion that recommends plants based on
your climate, sunlight, soil, and growing zone — and keeps all
your gardens, notes, and photos synced across your devices.
Auction Calculator
A specialized tool for collectors to calculate true auction costs,
including buyer’s premiums, taxes, shipping, and currency conversion.
Fast, accurate, and tuned for hobbyists and professionals.
Future Projects
We’re expanding into smart utilities, productivity tools, and
helpful hobbyist apps — each built with clarity, ease-of-use,
and precise engineering.
Our Philosophy
Simple. Useful. Built with care.
At SPQR Developers, every feature starts with a real user problem.
We prefer clarity over complexity, performance over bloat, and
craftsmanship over shortcuts.
Whether it’s calculating an auction fee or choosing the right plant for your yard,
our goal is always the same:
deliver tools you can trust — every day.
