An app built around how you work.

Not a template with your logo on it. I build each app from scratch around the way you already do things: your groups, your categories, your wording, the exact message your team sends today. It replaces the WhatsApp lists and spreadsheets you keep by hand, and sits on your phone's home screen like a normal app.

Made for you, priced for you, no monthly fees. Organisations: tell me your budget. You try a working copy before it goes live.

What it costs you now

Manual admin is never free.

Put in your own numbers. Typing, checking and re-sending the same list adds up fast.

Time spent a year 260 hours

That is about 33 full working days, every year.

The alternative most teams look at is a subscription app charged per user, every month, for as long as you use it. Mine is one price, then hosted free on your own account.

Pricing

Fair for students. Flexible for organisations.

Every app is made to measure. The price is fixed in writing after a short chat, before any work starts.

Organisations

Your budget

Clubs, CCAs, tuition centres, coaches, charities and small companies.

  • Tell me your budget. I'll show you what fits it, and what a little more would add
  • One link for everyone, no accounts or passwords for your members
  • Each person fills in their part, the app adds it up and writes the WhatsApp summary
  • Data in a Google Sheet your organisation owns
  • A one-page guide with QR code for your people

Shaped to your team: your groups and roles, your categories, your message format word for word. Examples: attendance sheets, session bookings, duty rosters, equipment sign-out, sign-up sheets.

Two demos you can tap

Copies of my own two apps, filled with made-up data. Tap the days, flip the cards, tick things off. Nothing is saved or sent. Yours would be built around your own subjects, plans and routine.

Study Buddy

Built around one diploma's timetable, modules and assessment style: classes and rooms, assessments counting down, notes, flashcards, and one search across every slide and guideline in the course. Classmates use it too, each with their own data in their own Google account.

Life Admin

Built around my own week: my trainer's programme, my own gym days, my bills and my review routine. It pulls in my sports watch and calendar, so I plan in one place and track in the apps I already use. Locked with Face ID.

How a job runs

From chat to app on your phone

  1. Chat

    Tell me what you do by hand today. Screenshots of your current list or chat help most. Free.

  2. Scope and price

    I write down what the app will and won't do, with a fixed price. Nothing starts until you agree.

  3. Test copy

    You and your team try a working copy and tell me what to change.

  4. Live

    It goes live on your account, with a one-page guide and QR code.

  5. Two weeks' cover

    Anything that breaks in the first two weeks, I fix free.

Questions

Before you message

Is there a monthly fee?

Not to me. The apps run on Google's and Cloudflare's free plans under your own account. Small teams stay well inside the free limits.

Do my members need to download anything?

No. It's a web link. They can add it to their home screen and it opens like an app, on iPhone or Android.

Where does our data go?

Into a Google Sheet or Drive folder you own. I don't keep a copy. If you stop using the app, the sheet is still yours and readable.

Can you change it later?

Yes. Bug fixes in the first two weeks are free. New features or bigger changes after that are quoted per job.

Will you build my school project?

No. I build tools that help you study and stay organised, not work you submit for marks. If an app idea is part of an assignment, I can talk it through with you, but you build it.

Why are student prices lower?

Because I'm a student too, and a good planner shouldn't depend on your budget. Organisations pay for the extra work a team app needs: more people, more roles, a handover guide.

How do you build so fast?

I design the app, decide what goes in, test it and set it up. Claude, an AI model, writes most of the code to my spec. That's how one person ships a working app in days.

What can't you build?

Payment processing, app-store apps, or anything that needs a big shared database for thousands of users. For those, I'll tell you up front and point you elsewhere.

Show me how you do it now.

Send me a screenshot of your list, sheet or group chat on Carousell. I'll build the app around it, and tell you roughly what it costs before you commit to anything.

I study full-time, so I take on a few projects at a time. Message early if you have a date in mind.
