Frequently asked
What is Pulso?
Pulso is a free app that puts Medellín's public environmental and mobility data on one map — rain radar, river levels, air quality, weather, the Metro and EnCicla bikes — pulled live from SIATA and other open sources, with push alerts when conditions change.
Where does the data come from?
From public sources: SIATA (rain, radar, river levels, air quality, weather), Metro de Medellín (stations and lines), the Colombian open-data portal, and CityBikes (EnCicla). Pulso has no official relationship with any of them — it uses their public data with attribution.
Is Pulso an official emergency service?
No. Pulso is a viewer of public data. It is not an early-warning system and must not be used as the sole basis for decisions affecting life, health, safety or property. In an emergency, call 123 or follow SIATA, DAGRD, and the Área Metropolitana. Read the Terms of Use.
Does Pulso track my location?
Not continuously — there is no tracking, no background location and no history. Pulso may ask permission to take one reading: on iOS when you tap “Use my location” in Alerts, and when you open the forecast if you already granted it; on Android the first time you open the forecast. That single reading is matched against the municipal boundaries bundled in the app, the zone name is kept and the coordinate is discarded immediately. You can skip it entirely and pick your municipality from a list. The map is always centred on the Aburrá Valley, not on you. See the Privacy Policy.
Does Pulso have ads or accounts?
No accounts, no sign-up, no email asked. No ads, no in-app purchases, no advertising identifiers (IDFA/AAID), no tracking. Pulso is free.
The data looks wrong, stale, or missing. Why?
Pulso shows what its sources publish. If a SIATA station is broken, a sensor reports an impossible value, or a source stops publishing, Pulso shows that as honestly as it can — but it cannot substitute for the missing measurement. The app shows the time of the most recent reading and labels previously saved data when it serves it. A value with an old timestamp describes the past, not the present.
The rain radar isn't loading.
The radar may be out of service due to SIATA maintenance or upgrade work. Pulso tries to warn you when SIATA announces it, but cannot always detect it. It also caches the last radar image (up to 6 hours) so you still see something if connectivity drops.
I'm not getting push notifications.
Notifications travel over services we don't control (Firebase Cloud Messaging, Apple APNs), across your carrier's network, and are presented by your device's OS. A notification may fail because of no connectivity, low battery, power-saving mode, Do Not Disturb, disabled notification permission, or OS restrictions. Delivery is not guaranteed — the absence of an alert does not mean the absence of danger. Check that Pulso's notifications are enabled in system settings.
How do I stop notifications?
Turn off Pulso's notifications in system settings: iOS Settings → Pulso → Notifications; Android Settings → Apps → Pulso → Notifications.
How do I delete my data?
Pulso holds no data that identifies you. Your preferences and caches live only on your device and are removed when you uninstall the app. The anonymous crash and analytics data described in the Privacy Policy cannot be associated with you after uninstalling. For any request, email grappestudio@gmail.com.
When will Pulso be available?
Pulso is live on the App Store for iOS. The Android version is in testing on Google Play — anyone can join the beta.
