Letting go

Letting go

After more than 7 years maintaining CambiosUY it’s time to say goodbye. It has been a great experience developing this app and getting so much great feedback.

I started developing CambiosUY just to learn how to develop an app for iOS. I wanted to do something simple and useful. In Uruguay we still rely so much on the US dollars for big purchases like cars, houses and even some electronics. The price of the currency goes up and down, so it’s useful to have some way of checking what the price is before you decide to do a purchase like this. We also use other currencies when we travel, for example Argentinian pesos when we travel to our neighbor country or Euros when traveling to Europe.

Basically, the app was divided in 3 sections:

– One where you could choose between 7 currencies and see what was the price for that currency. In this section you could also see the evolution of the currency over the last week, month and year. There was also a recommendation whether it was a good moment to buy or sell the currency. This was based on the current price and whether the value was higher or lower compared to the one over the last weeks, months or year.

– Another section where you could use your current location to see money exchange places to buy or sell foreign currencies.

– And finally, one of the most useful to me, that was a calculator that told you the equivalent value of some currency. For example if you have 40 Uruguayan pesos you could get 1 dollar, and so on.

At some point, I added an in app-purchase feature that sent notifications when a certain currency went above or below a certain threshold. This was useful for people that were waiting for a certain currency to go down so they could buy it at a lower price, or sell it when the price increased.

After a couple of months that I released the app, and with the help of some ads, I managed to turn CambiosUY in the most downloaded app in the iOS store for a few days. This was huge to me, the app was being downloaded more than Facebook, Whatsapp or the most successful apps at the moment.


So, after all this, why letting the app go?

Many reasons, but the main one is that I would like to focus in other things. The apps is no longer being used as much as it used to. I haven’t added any new feature or improved the app in the last few years. Sometimes we carry over with many things that doesn’t help us move forward, so it’s better to just let it go.

It was a great experience, and I would like to write about lessons learned and the technical details of how I implemented the app in the future. But for now it’s time to say goodbye and think in what to do next.
