Pulso

Pulso puts what SIATA publishes about Medellín's Aburrá Valley on one map: where
it is raining right now, how the rivers are running, what the air is like and what
tomorrow looks like.

Pulso is an independent app. It does not represent SIATA, the Área
Metropolitana del Valle de Aburrá or any other government entity, and is not
affiliated with them. It uses only public data, published by those same
organisations.

WHAT YOU CAN SEE
• Rain radar, animated over the last hour
• River and stream levels, in the risk colour SIATA reports
• Air quality: overall AQI, PM2.5, PM10, O₃ and NO₂
• Temperature and wind by station
• Two-day forecast for all 13 municipalities and corregimientos
• Medellín Metro, EnCicla bike share and the valley's bus routes
• Compressed natural gas prices

BUILT FOR A VALLEY WITH REAL RISK
When a layer comes up empty, Pulso tells you why: the data did not arrive, SIATA
is not responding, or you have no connection. An empty map is not the same as a
calm valley, and this app does not present it as one. Every screen shows the time
of the data you are looking at, and offline it shows the last saved data, labelled
as saved.

OPTIONAL ALERTS
You can switch on severe-event alerts in Settings. Alerts only — never
advertising. The data depends on what SIATA publishes, so Pulso cannot guarantee
an alert will always arrive.

NO ACCOUNTS, NO ADS
No sign-up, and we do not sell data. Pulso may ask for your location to work out
which municipality you are in; only the municipality is saved, never your
coordinates, and you can decline.

DATA SOURCES
Pulso is an independent app and does not represent any government entity. All
data is public: Pulso only reads what these organisations publish on their own
channels. It has no privileged access, no
agreement and no reserved channel.
