History

How the rate moved

6 hours, 24 hours, 7 days or 30 days. A rate holds until it changes, and the chart draws it that way — no invented curves between points.

We'll tell you when it hits

Create an alert in two taps and get a notification when the best rate crosses your target, or get the rate at the time and on the days you choose. In soles, or in pesos on the TRM. No account, no e-mail address.

Frequently asked questions

What does it cost?

Nothing. pulsoFX is free, with no ads and no in-app purchases.

Where do the rates come from?

From each exchange house's public pages, checked every minute, plus the official rate published by the SBS as the SUNAT reference. Colombia's TRM is the rate certified by the Superintendencia Financiera de Colombia, taken from the open data on datos.gov.co.

What happens when a house stops publishing?

We mark it outdated and leave it out of the best-rate picks, instead of showing an old number as if it were current.

Does it work for Colombia?

Only to follow the official TRM (USD/COP): the rate, its history, alerts in pesos and widgets. We don't compare exchange houses in Colombia.

Do I need an account?

No. The app has no sign-up and no login.

How do alerts work?

Pick buy or sell and a target rate, and you get a notification when the best rate crosses it. In pesos, the alert follows the TRM. It needs notification permission; a target that has already been crossed will not fire.

What data do you keep?

If you turn on alerts we store your device's push identifier and the alert you created. Nothing else is linked to you. The privacy policy has the full detail.

Is there an Android version?

It is in development. The iPhone app is the one you can use today.
