We make software
worth keeping.

Praelion is a UK software company. We make four apps of our own, and we design, build and look after apps, websites and digital services.

Heedli home: keep a moment, My Say, letters and the young person hub
Sealed Scene: guided capture, one shot at a time
Lulnara Today: the last feed, sleep and change at a glance
Gutbean Insights: the likely links Gus has found
Heedli insights: common triggers and times of day

Praelion is a software company in Manchester. We make Lulnara for new parents, Heedli for SEND families, Gutbean for anyone tracing what upsets their gut, and Sealed Scene for photo and video evidence. Then we stay, keeping each one fast, secure and up to date.

Selected work

Our own products, from the app on the phone to the website that explains it. Lulnara and Heedli are live on version 2. Gutbean and Sealed Scene are coming soon.

New: version 2.0

Lulnara

Your baby’s day, calm at a glance.

A shared baby-care record for new parents. Feeds, sleep and changes logged in a tap or by voice, timers on the Lock Screen and Apple Watch, and one day everyone who helps can see. In English and Arabic.

Gutbean

Find what upsets your gut.

A food and symptom diary. Write, snap or say what you eat and how you feel, and Gus, your gut detective, shows you the likely links and the evidence behind them. Patterns to take to your doctor, never a diagnosis.

Sealed Scene

Seal what happened.

Photo and video evidence, sealed at capture. Every file gets a fingerprint and a date from an independent timestamp authority, and anyone you send it to can check it in a browser, with nothing to install.

Sealed Scene: a shot list for the job
Sealed Scene: guided capture, one shot at a time
Sealed Scene: a file checked in the browser, sealed and unchanged

What we make

Most projects need more than one of these. Each starts with the same question: what does this have to do for the person using it?

  • iOS & Android

    Apps

    Mobile apps that feel at home on the phone, from first prototype to App Store and Google Play release.

  • Sites & web apps

    Websites

    Fast, accessible websites and web apps that are easy to update and easy to find.

  • Research to interface

    Product design

    Flows, interfaces and the words on screen, shaped with real people before anything is built.

  • Where it earns its place

    AI features

    Voice input, drafting and summaries that save time, with a person checking the result.

  • After launch

    Long-term care

    Updates, fixes, new OS releases and new features, so what we build keeps working.

How we work

Five steps, on every project. The last one doesn’t really end.

  1. 01

    Understand

    We start with the people who will use it and the job it has to do, and agree what good looks like before anything is drawn.

  2. 02

    Design

    Flows, interface and words, prototyped early so decisions are made on something you can hold, not a description.

  3. 03

    Build

    Apps, websites and the services behind them, built in small steps you can see and try as we go.

  4. 04

    Launch

    Store submissions, hosting, analytics and accessibility checks, planned ahead so release day is calm.

  5. 05

    Look after

    Fixes, updates, new OS versions and new features. Software keeps working because someone keeps looking after it.
