Our vision
We rethink apps for the AI era.
AI changes software twice: how it is made, and what it can do for the
person using it. We work on both at once.
Engine 1Built at AI speed
An AI-first production line turns months into days. Building an app becomes so
cheap that we can serve the niches incumbents ignore – and ship improvements every week
instead of every quarter.
Engine 2Apps that think with you
Inside every app, AI takes over the step people hate and adds an expert at their
side. Not a chatbot bolted on – the product itself becomes adaptive, personal and
measurably better for the customer.
Proven category × the step everyone hates × an AI leap.
How we work
A one-human company.
Behind every app sits an organisation of AI agents: they research, design, code, test,
illustrate and voice. One human makes the calls – and the agents only get as much freedom as they have earned.

Ubo – AI vocabulary trainer
Snap a page of any textbook and Claude on Amazon Bedrock turns it into
structured flashcards after a short wait – any publisher, any edition, five languages. Neural
pronunciation from Amazon Polly, speaking practice with
on-device speech recognition: the microphone never leaves the phone.
Fully serverless on AWS Lambda.

Kids' puzzle book – grades 1 and 2
30 puzzle types – mazes, sudoku, number walls, detective puzzles and more. Each type has its own
generator, built by AI agents: it creates new puzzles every time, and a solver checks
every single one before a child sees it. Plus 214 AI illustrations from the local GPU
pipeline and 759 read-aloud tasks. Built in one night.

Next up: Ubo Coach
Generic AI tutors know everything – except what is in Thursday's test.
Ubo already holds the vocabulary from the child's own textbook. Ubo Coach turns it into a
personal language coach that gets to know each learner over months and years – their
strengths, their recurring weak spots, what works for them – and helps them grow. The
longer you learn with it, the better it knows you. And that knowledge stays on your device.
- Stage 1
Understand mistakes
AI recognises why an answer was wrong – false friend, spelling, gender, a mix-up – and gives a one-line memory hook.
- Stage 2
Knows you, coaches you
A learner profile that grows with every round: strengths and weak spots across tests, school years and languages. The coach reshapes the plan up to test day and keeps working on what still wobbles long after it.
- Stage 3
Speak it
Guided role-plays – at the bakery, at the station, with a new classmate – built from exactly this week's words. Speech recognition stays on the phone.
More apps are on the way – and every new app makes the AI organisation behind them better.

Patrick Steinborn
Product leader with more than 20 years in consumer internet, most of them at VP
level – growth, monetisation, pricing and AI transformation for products used by
millions. He started Remindery Apps in 2026 to prove a simple thesis: with the right
operating model, one person can run what used to take a whole team.
He builds every day, hands-on, with Claude Code as his main tool.

What we stand for
- Users at the centre. Every app starts with the question of what helps the people who use it. For children, that means no ads, no tracking, no dark patterns – and learning progress stays on the device.
- The next generation of apps. AI is not a bolt-on extra for us but the core: our apps take over the tedious work, get to know their users and get better week after week.
- A human has the final say. Agents build, a human decides: a person tests and approves every new app version before it goes to the store – and a person has checked every story and every picture in Silben Lesen before it went into the app.
- Private by default. Whatever can be done on the device stays there. Whatever has to leave it is kept only as long as necessary and never used for advertising.
Let's talk.
