The Palmtop Guide

Palmtop is a phone that makes its own software. You describe what you need in a sentence, and a small app appears on your grid — a list, a form, a tracker, a board. It is yours: you keep it, change it by asking, and hand it to other people if you want to.

This guide is in four parts. The basics is everything one person needs. With other people is sharing, groups and forms that answer back. At work is what teams and businesses use it for, by situation. How it fits together is the shape of the system, so you can judge whether it belongs in your business.

You do not need to read it in order. If you have five minutes, read the basics and make something.

1 · The basics

Getting it

Three ways, same Palmtop:

Web app Open it in your phone's browser and add it to the Home Screen. Nothing to install, works on any phone, and it is the version that can ring you.
iPhone From the App Store, or the TestFlight beta while the current version is in review.
Android From Google Play.

Whichever you pick, your apps live on that phone. There is no account to make and nothing to sign in to.

Making your first app

Tap Build, and say what you want in plain words:

A list of what to buy for the shop, with prices and a running total.

A minute later it is on your grid. Open it and use it. If it is not quite right, say so — "put the total at the top", "add a column for the supplier" — and it changes. You are not editing anything; you are describing it.

Two things help more than anything else:

Starting from something that exists

+ New → Gallery has ready-made apps: an order form, a sign-up sheet, a poll, a checklist, an expense splitter, and a set of work ones (a shift board, an incident board, a trade blotter, alerts). Install one and then make it yours by asking. Starting from a working app and changing it is usually faster than starting from a sentence.

Where your things live

Everything — the apps and what you put into them — is on your phone. Not on our servers, not in an account. That has one consequence worth knowing:

Back it up. Settings → Back up everything writes a single file. It contains your apps, your data, and the private half of anything other people are relying on: the board your servers send alerts to, the inbox your shared forms send orders to. Restoring it on a new phone picks all of that up exactly where it left off. Keep the file somewhere only you can read.

Keeping the old one

Duplicate (in an app's menu) makes this week's from last week's and leaves the old one alone, with its data, as a record. It is the right move whenever something is periodic — a weekly order form, a monthly count, a per-event sign-up sheet.

On a computer

The web app opens on a laptop or a desktop too, at the same address. It uses the whole window, with your apps down the left, and an app built for a wide screen gets the room. It is the same Palmtop, the same apps.

2 · With other people

Palmtop is built around handing things to people, not around inviting them to a platform. Nobody you share with has to make an account.

Sending an app to someone

An app's menu has Share. You get a link (or a file, for the places links cannot go). They open it, see what it is and what it contains, and confirm. Then it is on their grid, theirs to change.

You choose whether your data goes with it. A blank checklist and a filled-in one are different gifts — sometimes the filled-in list is the whole point. Anything you would rather keep — your notes about a customer, your own running total — can be marked as yours and never travels, even when the data does.

Two kinds of app

Worth knowing before you build something for work, because it decides what you can hand to a colleague.

Most apps are yours to hand around. Everything they need is inside them, so the copy you send works exactly as yours does — the order form, the checklist, the rota, the poll.

Some apps reach your computer: they read a file, query a database, render a report, print something. Those are pinned to the machine that built them, on purpose.

What travels when you share an app An app you hand around goes whole: the copy your friend gets works exactly as yours does. An app that uses your computer travels as its phone half only — the part that reads your files stays on your machine, and never answers an app that arrived from someone else. AN APP YOU HAND AROUND Your phone the app you built Their phone the same app, theirs now all of it goes AN APP THAT USES YOUR COMPUTER Your phone the same app, plus reach Their phone the phone half, on its own only the phone half goes Your computer the part that reads your files stays here — and never answers an app that arrived
An ordinary app travels whole. An app that uses your computer travels as its phone half.

So: hand the order form to anyone. Keep the app that reads your trading files on the machine that has them. If a colleague needs the same thing, they set up their own computer side in a minute, and their data stays theirs — which is usually what you wanted anyway.

Circles

A circle is a family, a class, a team or a group of friends who share apps with one tap. Post an app to a circle and everyone gets Install; post a change and everyone gets Update. A circle has no owner and no server-side membership list: it is a shared key that the people in it hold.

Forms that answer back

This is the one that surprises people. Share a form — an order, a sign-up, a poll, an RSVP — and the answers come back to you, into the app you shared. Not to us; we cannot read them.

Where the replies go You share a form as a link. Anyone you send it to fills it in with no account and nothing to install. Their replies come back, sealed, into your copy of the app on your phone — never to us. Your phone the form you built, and every reply to it Anyone you send the link to no account, nothing to install you share a link their replies come back to you — sealed on the way, and never to us
You share a link; the answers come back into your copy of the app.

That is a whole small business's worth of machinery — take orders, see who ordered what, chase the ones who have not — with no accounts, no subscriptions and no customer list anywhere but your phone.

3 · At work

Palmtop is not a replacement for the systems a business runs on. It is for the gap those systems leave: the thing your team currently does in a spreadsheet, a group chat or somebody's head.

Each of these is a real starting point. Install the template, then describe your version of it.

Taking orders from customers

Start from: Order form · Good for: a farm, a bakery, a supplier, anyone with a weekly list and regular customers.

Share the form with customers by link. Orders arrive on your phone as they come in, grouped and totalled the way you asked for. Next week, Duplicate it and the old one stays as the record of what went out. Prices, minimums, cut-off times and "we are away until the 14th" are all just things you ask for.

It will not take card payments, or tell you what to do when you are out of stock. It will tell you who ordered what, immediately, for nothing.

A team's rota, checklists and sign-offs

Start from: Shift board, Checklist · Good for: shops, kitchens, clinics, sites, anywhere with shifts and a handover.

A board everyone has on their phone, that says who is on, what has been done and what is left. Circles keep it in step across the team. Sign-offs — opening checks, cleaning, safety — become a tap with a name and a time against them, which is usually the whole audit trail anyone needs.

It will not be your HR system, and it does not do approvals or payroll.

Knowing when something breaks

Start from: Alerts, Incidents · Good for: anyone running systems that matter — a trading desk, a service, a pipeline, a line.

Your systems already know when something is wrong. Palmtop is how a person finds out. You put a small program on the machines that stay awake — a server, a build runner, whatever raises the alarm today — and it puts alerts on your phone: a severity, what broke, and where to look. Serious ones ring the phone and stay on the screen until dealt with; the rest wait quietly on a board.

How an alert reaches you Your own systems raise an alert. Palmtop Link, on a machine that stays awake, seals it and sends it. The relay carries it and wakes your phone. It lands on your board and rings for a serious one. Separately, the same machine can place a phone call, which is the only route that is a guarantee. Your systems something breaks Palmtop Link on a machine that is awake our relay cannot read it Your phone on the board, always ringing for a sev1 sealed here …and the same machine can place a phone call — the only route that is a guarantee
Four hops, and the honest one at the bottom: a call is the only route that is a guarantee.

What makes it usable rather than noisy:

Be honest with your team about the limit: this tells people, it does not guarantee them. A phone that is off finds out when it comes back. For a genuine 3am page, have it place a phone call as well — it can, through your own telephony account.

There is a separate guide for wiring this into your systems; see the end.

The desk's numbers

Start from: Blotter · Good for: trading desks, ops teams, anyone who starts the day with the same handful of figures.

Fills, positions, breaks, the checks you run every morning — on your phone, from the files or systems that already hold them, arranged the way you actually read them. The work happens on your computer, where the data already is; the phone is the screen.

It will not connect to your database on its own. Someone decides, once, which specific things the phone may ask your computer for, and the phone can only ask for those by name. This is an app of the second kind — see Two kinds of app — so it stays on the machine that has the data.

Field work

Start from: Checklist, Sign-up sheet · Good for: inspections, deliveries, events, surveys.

Phones are good at this and the software usually is not. A form built for one job, used offline, photographs where you need them, and the results collected back to whoever sent it out.

4 · How it fits together

There are two kinds of part, and it is worth keeping them apart: the app you use, and the things that power it. Most people only ever meet the first.

The parts of Palmtop On the left, the app you use, on your phone and your computer, where everything you make lives. In the middle, a relay that carries sealed messages it cannot read. On the right, the two optional parts: Palmtop Hub on your computer, which the phone can also reach directly on your own network, and Palmtop Link on machines that stay awake, which only ever sends. WHAT YOU USE The app your phone your computer everything you make lives here our relay carries; cannot read WHAT POWERS IT — OPTIONAL Palmtop Hub your own AI, your own files Palmtop Link alerts from your systems only ever sends the hub can also be reached directly, on your own network
The app holds everything. The two parts on the right are optional, and the relay in the middle carries sealed messages it cannot open.

What you use

The app On your phone, and in a browser on a computer — the same apps, the same data, the whole window when there is room for it. Everything: your apps and what is in them. The only place your data is readable.

What powers it — both optional, both yours

Palmtop Hub Runs on your computer. Builds your apps with the AI subscription you already pay for, keeps them in version control, and lets an app reach a file, a database or a printer that never leaves the machine. Only what is on that computer already. It answers your phone; it never reaches out to us.
Palmtop Link Runs on machines that stay awake — a server, a build runner, an always-on box — so they can tell you when something breaks. A one-way credential for one phone's alert board. Nothing else.

Neither is needed to use Palmtop. You add the hub when you want more building power or your own files; you add Link when something in production has to be able to reach you.

And one thing in the middle

Our relay The single service we run. It passes sealed messages between the parts above, and wakes your phone when something needs you. Sealed bytes it cannot open, and the minimum needed to route them.

The one rule that shapes everything else: anything that leaves your phone is sealed on your phone first, with keys that stay on it. We carry it; we cannot read it. That is why there are no accounts to make — there is nothing for an account to protect.

What each can and cannot do

When you want it on your own infrastructure

For businesses that cannot use a shared service — compliance, policy, or simple preference — everything here can run entirely on infrastructure you control, with no dependency on ours. That is a conversation rather than a download; ask us.
