J. R. Haigh's recommendations for Android
'''F-Droid (https://f-droid.org/ )''' (GPLv3+) – libre software repository, from which the following can be downloaded (To install, you need to enable ‘unknown sources’ because it is separate from Google.); |
'''FAST App Search Tool''' (GPLv3) – quick application launcher from double-clicking or up-swiping the home button; |
'''Hanger''' (GPLv3) – recent application launcher widget for notification bar (tip: pin FAST so that you can quickly get to applications that have fallen off the list); |
'''Kiwix''' (GPLv3) – offline Wiktionary, Wikipedia, etc.; |
'''LibreTorrent''' (GPLv3) – reliably download large files such as those used by Kiwix; |
'''RPN''' (GPLv3+) – step-by-step calculator with no need for parentheses (e.g. try pressing [[1]], [[Enter]], [[2]], [[Enter]], [[3]], [[×]], [[+]] and compare this with [[1]], [[Enter]], [[2]], [[+]], [[3]], [[×]]); |

All of these applications are libre software (you are free to use, study, modify, and share them) and the offline content files for OpenStreetMap and Wikimedia's wikis are also libre.
