I'm a Software Developer from Helsinki, Finland. I create apps for iOS using Swift.
I have created and published 30+ different apps from various categories on the App Store as a hobby. They have been downloaded 140k+ times from over 150 countries.
Currently, I have 4 apps published, and two of them have reached #1 of Paid Apps on the App Store.
Topo Maps, my most popular app. I released it in May 2015. It includes topographic maps to 16 countries.
The iOS app is made using Swift, and the backend is a combination of NodeJS, PHP, and Python.
The app includes many features, such as bookmarks, search, map downloading, route recording, measuring distances, location sharing via a server, and many others.
These apps are only available on the Finnish App Store:
Nautical Charts (Finland) This app is based on the same codebase as my Topo Maps app.
Nature contains 1400 species from the Finnish nature.
ATMs (Finland) displays all ATMs in Finland sorted by the distance from the current location.
It is written in Swift, and I've published its code publicly on GitHub.
