The app was written in Python and started out for the HP-45 (ROM is included) but finally included also the HP-35 and the HP-80, as well as three others. For macOS and Windows you could just run the included executables, or with the Python code, this will run fine on Linux if you have Python installed. Nice thing is that you can also modify or tweak the Python code if you wish.

As she states, this is not a "how to learn HP or RPN" but there is a lot of included online help, and the original HP manuals are available online.

What an amazing resource for anyone wanting to learn more about the inner workings of these legendary calculators.

The app is made specifically for casual contributors and beginners as no prior knowledge about OpenStreetMap (such as tagging schemes) is required to contribute with this app. Furthermore, there is a bit of gamification and statistics that aim to introduce and try to inspire users to venture deeper into the world of OpenStreetMap.

This app finds missing map data in your vicinity and displays it on a map as quests. Solve each quest by visiting the location on-site and answering a simple question to update the map.

The info you enter is directly added to OpenStreetMap in your name, without the need to use another editor. OpenStreetMap is a really valuable free resource that anyone can contribute to, and which numerous mobile apps also use for their navigation. It is the Wikipedia of Mapping!

The app is open source and is available both on the Google app store but also on the F-Droid store.
