A neighbourhood that stays in touch.
QuartierApp connects neighbours, families and neighbourhoods so that nobody quietly slips out of view. Simple to use — especially for people who are often left alone with the usual technology.
01 — The problem
Who notices when someone quietly slips out of view?
Closeness happens less on its own these days. People living alone do not always get in touch — and relatives often live far away. The intention to drop by is easily postponed, until a good thought has turned into a too-late.
QuartierApp wants to close that gap without being intrusive: a quiet line between neighbours, family and neighbourhood.
02 — What QuartierApp does
Stay close, without the effort
Not another loud app. A few quiet paths, so that contact and help stay easy day to day.
A line that stays open
Neighbours and family stay connected without constantly having to ask. A short hello is enough to make clear: all is well.
Small help, quickly asked for
A bit of shopping, an errand, someone to listen: whoever needs something just asks — whoever can help, sees it. A neighbourhood finding its way back together.
Large type, clear paths
Built for people who struggle with the usual technology: calm, understandable, with read-aloud output and visible contrast.
03 — Trust
Data about people who need protecting.
QuartierApp is meant for older people and their relatives. Data like that deserves particular care — which is why privacy here is not a footnote but part of how it is built.
- Sparing with data, clear roles, processing in the EU. Who sees what is governed in a way you can follow.
- No selling of data, no tracking, no advertising. The closed pilot starts without any public flow of data.
- People decide, not automation. The important steps stay in the hands of those involved.
Technology for older people must never be complicated. If it is, I have not done my job.
04 — Where it stands
A closed pilot — deliberately small.
QuartierApp currently runs as a closed pilot with individual families. No public launch, no advertising — first it has to hold up in real everyday life, then it opens.
If you are a neighbourhood, an institution or a family this might fit, I would be glad to talk.
05 — Taking part
Does QuartierApp fit your neighbourhood?
Pilot partners and relatives who want to be involved early are best off getting in touch directly.
