Show HN: I give you the most suitable outfit to wear depending on weather

I learned a lot while coding this little side project app on Android and iOS, like using the OpenWeather API.

I created the algorithms to propose the suitable outfit for the day anywhere in the world. It took some time to assembly and think about the looks and the illustrations. But I want to talk to you about my biggest pain: the timezone module.

It was very difficult to get the app working on every timezone of the world. Indeed, I wanted to give weather from morning to night but I needed to know what time was at every town of the world (to display only 4 simple informations : morning, afternoon, evening, night). At fist, I wanted to use the Google Timezone API but it was very expensive.

My first solution was to use Kevin Robert module called city-timezone, it covered 80% of the users requests. Sometimes the city is not found, in this case I choose a timezone list from the web that I parsed, then I used another list for the towns of the world with a timezone indication code inside. So I was able to match the town with the timezone when a user select a town. And finally, if the timezone of the town is still not found, I use timezonedb API (link below) who let me cover at the end almost all the town of the world.

I also set things to not call too much the weather API (like if you want to get the weather 8 mins later at the same position, I didn’t call again the API, I save it for 10 mins inside the app).

The app is still in progress, because I want to add an Inspiration section and to create a more complex outfit proposition algorithm (I like it so far, but I think it can be improved). I already got design feedback by a UX/UI designer that helped me to think about the future experience inside this little app. I also used the Humaaans illustration base and recreated clothes on top, it was very creative and fun to do.

Fun fact: I wanted to create this app at the beginning only for Men living in Paris, France because it was my actual pain: what outfit I should prepare to look my best throughout the full day? And now, my biggest users this month (51%) are Women living in US and UK. It took me a huge amount of time to create english speaker and Women version of the app, but it was a great idea to offer the app to as many people as possible from the beginning, because my target users revealed itself.
