I built Trek after splitting costs on road trips with friends

I'm Jozef, a European living in South America. On a three-person road trip to Bolivia, only two of us installed the expense app. We had to manage spending in Paraguayan guaraní, Bolivian bolivianos and US dollars.

On a later trip to Buenos Aires there were four of us, more currencies and again someone who didn't want to install an app. I sent the final balances through WhatsApp and Signal because everyone wanted to see the result.

Afterwards, friends also asked what the Bolivia trip had cost, how much a restaurant meal cost and which places were worth visiting.

That's why I built Trek: to keep track of the trip's costs, work out who owes whom and share a link that friends can open without installing the app.

What Trek does

• Log stops with photos, expenses and notes
• Multiple currencies with automatic exchange rates
• Works out who owes whom
• Friends can join by link, no account needed
• Share the whole trip as a read-only link
• Free for one trip, with more in Trek Plus
