Our
laboratory.
We don't just take briefs. We build our own products, with the same principles we work by for you. Here they are.
Why we have a Lab
When the client
is us.
We build our own products with the same judgement we use when we build for you. Every product is different, but the way we think about them isn't.
We feel the pain before you do
We use every Lab tool ourselves, every day, before we publish it. If it annoys us, it doesn't ship. We test on our own skin what we then hand to you.
One thing, done well
We don't pad out feature lists to look bigger. Each product does one thing and does it well. The rest is clutter.
No small print
No hidden subscriptions, no terms that turn up later. What you see is what's there. Just like when we work for you.
Flagship products
Real product,
with real technology.
ResidenceSafe
Turns a daily selfie into legal proof of where you've been.
A presence-certification app for digital nomads and expats. Biometrics, certified GPS and a blockchain timestamp, with eIDAS 2 validity. Proof that holds up to a tax inspection, without watching you the rest of the day.
Tsubasign
Sign and verify documents with a blockchain timestamp.
The Tsuba family: digital signing and verification on the same technical base as Tsubacheck. A record no one can alter afterwards, for contracts and documents that have to hold.
Tsubacheck
A verification platform with facial biometrics (iProov) and a blockchain timestamp. Real R&D, a genuinely complex product.
Metriguest
BI for hospitality: production, bookings, pricing and hotel quality on a single screen.
VerySimpleCRM
A bespoke CRM that does what it should, without what it shouldn't. Just like the name says: genuinely simple.
Tsubacheck + Tsubasign + ResidenceSafe. Three products with real blockchain. This isn't "knowing a bit about it", it's a whole product line. See the blockchain service →
On the App Store and Google Play
Real apps,
published and live.
Anyone can search for them and download them. Own products, under RJ Digital Hub SLU.
Anchor
An offline personal CRM. Your network of contacts, on your phone and nobody else's.
Continuum
Read and listen to the same book, in sync. OCR from the physical book to the digital one.
Lab .ad
Tools we make
because we enjoy it.
Side-projects on the .ad domain. They show our technical curiosity, and along the way we master the .ad we also manage for you.

Andorra's fuel prices, at a glance. Small, useful, ours.
A simple link shortener. Because sometimes a well-made tool is enough.
Generate your app icon in every size the stores ask for. Fast and no sign-up.
Got a product in mind?
If you have an idea for your own product and you're looking for someone to build it with judgement, let's talk. We know what it takes to carry a product from idea to the App Store.
