The relaunch of Coe Operations is the direct result of a long retired computing consultant and lecturer being asked by their granddaughter for a World Flags app with maps on her phone. Now that it works as intended, it is offered free of charge to a wider audience.
It shall be released on Google Play Store after user preferences and layout (image sizes) on more devices have been addressed. In the meantime its beta release and associated offshoots are available on their respective web pages, as are the online versions that can be played in most browsers by clicking their icons below.
Whilst I do not guarantee responding to all emails, your feedback is most welcome, as is reporting any errors or broken hyperlinks.

Coe Operations Film Stars is an app about film stars where you can learn or be tested on your ability to identify them. It has just been released with about 130 stars, many more shall be added in the coming weeks and months.
There are links from their pictures to their corresponding Wikipedia bio page and to their filmography from in character shots, which have predominately been chosen from films suitable for a younger audience.

Gathering material for a Film Stars app began in early September 2025 as a surprise for my granddaughter's thirteenth birthday. Not exactly educational in the academic sense of the word but it is attuned to her interests. She is an attendee of the Pauline Quirke Academy of Performing Arts and something of an aficionado when it comes to films and who is in them.

Coe Operations World Flags is a test and training app to improve your knowledge of the world's flags, capital cities and the ability to place countries on a map. It includes links to Kiddle (Kids Encyclopedia Facts) or Wikipedia for further information. Click its icon to play online.
World Flags is the natural progression from a spreadsheet of European flags created years ago for my granddaughter and her primary school by her father, comprising hyperlinks to maps and Kiddle. When asked for an opinion, I immediately copied it to a simple web page as shown above.
I don't know how much it spurred her interest in flags and geography, but she can now identify most in an instant and asked for a flags test with maps on her phone while I was coding something else for personal use.
The following US States and GB Counties apps are exactly the same as their World Flags counterpart apart from their respective data and resource files. Downloading and installation is the same, as is playing online by clicking their respective icons.

An offline Android app for learning about and for testing you on US States, capitals and and their flags, although some states do like to spell things out.
