Counting is the first step.

Discover why we built Contalo and how one simple action can make something visible to everyone.

How it works

Step 1

Create counters in seconds

Give it a name, set a starting number, and you're counting. No setup, no menus to dig through.

Step 2

Invite friends

Send a link. Anyone who opens it can join the counter and start tapping — no account required.

Step 3

Count together, live

Every increment appears on everyone's screen instantly, so the number is never out of date.

Step 4

History and activity

See exactly who counted what and when, so there's never a dispute over the final tally.

Step 5

Beautiful statistics

Track trends over time and see who's contributing the most, with charts that update as you go.

Needs, causes, field signals.

Cities

Everyday problems, maps, services, real-time data.

Brands

Purpose, campaigns, participation.

Communities

Shared signals, culture, games.

Events

Attendance, finish lines, milestones, shared moments.
