RBP SYSTEMS · SOFTWARE FOR THE RASPBERRY PI

One family of assistants. Almost any business. Yours to own.

Private, pay-once software for the Raspberry Pi: for the household, the trades, the care home, the kitchen and the office. And when nothing on the shelf fits your work, we build the one that does.

WHAT WE HAVE BECOME

It started with one personal assistant. It grew into a family.

We began with three small programs for the home: one for your day, one for an aging parent’s medicines, one for a student’s classes. Then business owners started asking what one could do for them.

Today the family runs a care facility’s duty log and medicine pass, a painter’s room-by-room estimates, a roofer’s jobs, a kitchen’s plate costs, and a small office’s books and customer statements.

WHY A FAMILY, NOT A PILE OF APPS

Built from the same proven parts.

Learn one, know them all

Every assistant opens on the same desk, with the same contacts, places and items. Moving from one to the next is like moving to a new room in the same house.

One fix helps everyone

The books, the statements, the scheduling are shared. Improve them for one customer and every assistant in the family gets better.

Already working in the field

These parts run every day in real homes and businesses, so a new assistant is mostly assembly rather than invention.

CUSTOM SYSTEMS

Don’t see your business? We’ll build it. Most one-offs are done in under a month.

Most custom software starts from a blank page, and you pay for every hour of it. Ours starts from a family of working assistants. Most of what your business needs (scheduling, records, people, billing, statements) is already built and running. We adapt what fits and build only what is truly yours.

Less to build means less to bill, and less to wait for. That is why most one-offs are running in under a month, at a price you won’t find elsewhere.

We show you the parts that already fit your work, running.

We build the rest

You own it, it runs on a Pi in your shop, and nobody rents it back to you.

Put your Raspberry Pi to work. Or set one up for someone you love.

Three small programs that run on a Raspberry Pi you own: your calendar, your money, your contacts, your medicines. No cloud, no subscription, no account. Pay once and it is yours.

HAVE A PI IN A DRAWER?

Almost everyone who bought a Zero 2 W has one sitting idle — a project that fizzled, a board bought for someday. This is someday. Slot in a card, power up, and it is a complete private assistant. No flashing images, no command line.

BUYING FOR A PARENT?

The Senior Assistant puts large, clear type on their television — medicines and appointments that remind them when it is time, and a text to you if a dose is missed. You can set it up from your own house.

TRY IT BEFORE YOU BUY IT

The demos on this site are the real programs running live on a Raspberry Pi right now — not videos, not screenshots. Nothing is installed on your computer and nothing you type is kept.

OWN IT, DON'T RENT IT

Pay once. No subscription, no account. Every one of these runs offline on a small device you hold in your hand — and if you ever need help, you get the programmer who wrote it.
