From firefighters, for firefighters
We are building a digital incident logbook. We already tried once and never shipped it. This time we are going through with it — in public, and verifiably.
From firefighters, for firefighters
Incident documentation made easy
The digital Einsatztagebuch for fire and rescue services. Log radio traffic in seconds — with gloves on, at night, under pressure. Offline. Free. Forever.

This is what the entry stream looks like in the app
Today this still runs on paper
At almost every fire station in Germany, an incident begins with a sheet of paper. The Einsatztagebuch — the operations logbook — is where the radio operator writes down every message: who called, who answered, what was said, and when.
It is a legal record. It is also a mess of hurried handwriting, produced under stress, at night, sometimes with gloves on.
Roughly a million volunteer firefighters document this way. Paper still wins, because a pen has no navigation stack. That is the bar Einsatzlog is measured against.
What the app does
Everything serves one loop: alarm → create Einsatz → log radio traffic → close → PDF report.
An entry in under ten seconds
Timestamp automatic, message type one tap, From/To as suggestion chips drawn from the traffic so far. Four taps plus the message text — that is the design target, and it is written into the spec as an acceptance criterion.
Colour means message type
Funkspruch, Lagemeldung, Auftrag, Anforderung, Dokumentation — each type has its colour, like coloured pens on the paper form. It is the fastest way to find something again in the stream.
Offline is the normal case
No accounts, no sign-in, no connection required. In a basement, in the woods, in a dead spot — the app works completely. All incident data stays on the device.
Incident report as PDF
The payoff: the complete, chronological report to share, print and archive. Also available during a running incident, for the shift handover.
The record is sacred
Timestamps are set automatically. Closed incidents are read-only. Reopening one documents itself. Trustworthiness is a feature.
German and English
Fully bilingual from day one. Domain terms stay German — a Funkspruch is a Funkspruch in English too.
From the app
Light and dark are equal citizens — night operations are normal operations.

Einsatzlog in two minutes
The demo video is being made. Until then, the blog shows every step.
Free. Forever.
Fire departments have no app budget — and they should not need one. Einsatzlog is fully usable without paying a cent. There are no premium features, no user limits, no ads.
Anyone who wants to support the project can do so voluntarily inside the app: one-time donations or a small supporter subscription. It unlocks nothing — fire departments should not bid against each other for safety tooling. You get a badge and our thanks.
On top of that there is a fully open-source FOSS variant without any proprietary SDK.
Built in public
Einsatzlog is being built for the RevenueCat Shipaton 2026 — from the first napkin sketch to the app stores, in a public repository. Specs, design artifacts, roadmap and source are all open. The mistakes too.
