People ask what Parta is for. These are the situations it was built around. None of them are unusual, and the app is only useful in them because the work was done beforehand.
1. A group in the mountains
Somebody is hurt and cannot answer for themselves. The person making the call needs their blood type, allergies, medication and who to ring at home. Rescue statistics show that a large share of call-outs are medical rather than dramatic falls, so this comes up more often than people expect.
2. A week abroad
Five people, one booking, one insurance certificate, and the person carrying it is on the other side of the city. Documents and tickets sit in the group, so the group is never stuck waiting for one phone.
3. Out alone, with somebody watching
A long run, a solo ride, a night walk. You switch position sharing on for the hours you are out, one friend can see roughly where you were, and it stops when you stop it. Not a tracker: a habit of telling someone your plan.
4. A guided tour
A guide is responsible for people they met an hour ago. Guests join the group with a code before setting off and bring their own emergency contacts, conditions and insurance with them. No folder of photocopies, and no asking strangers about their health in front of everybody.
5. A school or club trip
Twenty families fill in their own details once, instead of twenty forms coming back half empty. Leaders see what the group agreed to share, and a changed phone number updates itself.
6. A festival or a weekend away
A crowd with no signal is how a group loses each other. The meeting point, the tickets and the beds are carried by everybody, and if a night ends in a hospital in a strange city, the friends who came along have the blood type, the allergies and the insurance.
What it does not do
Parta does not call for help, does not watch anyone, and cannot find a person. It holds what a group agreed to share, and shows the local emergency number wherever you are standing. Everything else is still up to the people on the trip.
