An app that works without a connection

In a lift, a car park or a basement the app does not turn into a white screen: what is already loaded opens, and what was sent is not lost.

Nobody has to think about signal. The catalogue and their bookings open where there is no internet; a request sent in a lift goes through by itself once the connection is back. No «try again» and no lost form.

  • catalogue and bookings open offline
  • what was sent does not vanish
  • no «please try again»

What's inside

Offline is not a mode to switch on: the app simply keeps working.

Local data

Catalogue, services, profile and history are available offline — from what is already loaded.

Action queue

An order, a booking or a message goes to the server once the connection is back.

Pass and documents

The entry code and saved documents open without internet.

An honest status

It is visible what has already gone and what is waiting for a connection — not «sent» after the fact.

Conflict resolution

If things changed while offline, the app says so instead of silently overwriting.

Less traffic

What changed is downloaded, not the whole catalogue again.

How it works

The rule is simple: reading from a local copy, writing through a queue. No step asks anything of the person.

We decide what to store

What must open offline: catalogue, bookings, pass, documents.

We set up the queue

Which actions wait for a connection and what the person sees while they wait.

We describe conflicts

What to do if the slot was taken or the price changed while there was no signal.

that signal cannot stop

Questions about working offline

Does the app work with no internet at all?

It opens and shows what has been loaded — yes. New data of course only arrives with a connection, but nobody hits an empty screen.

What happens to an order sent offline?

It queues up and goes through when the connection returns. The person sees that it is not confirmed yet, rather than a false «accepted».

And if the slot was taken meanwhile?

The app says so and offers another time. It will not quietly overwrite somebody else's booking.

Will a QR pass work in a basement gym?

Yes, the code is on the device. That is exactly the case offline exists for.
