  23. 23. Keeping the apps up to date • Example from this year • Android 9 – Rebuild – Switch from Eclipse to Android Studio – Switch to Gradle from ad hock build system – Remove ActionBarSherlock library – A lot of time spent fixing UX bugs and crashes on certain phones in certain conditions – Gmail sending bug – Still random crashes • Europeanna searches failing – Lots of tracking down and dead ends trying to find what the problem was – Trying to build a 3 year old web app with a complex toolchain, java scriot, ecs6, node, npm, bower, git
  24. 24. • Show the map! • Show the visualisation!
  25. 25. Monthly usage over 10 years
  26. 26. Listening to this morning. Heard a great tune…..interrupted by the Galway Races Used Tunepal……’s called The Parting………got it from The So much fun……….. listening and learning Irish Trad. Thank you so much for the good you have done and are doing! It is ironic, but one of my mates has proudly proclaimed she has never had a cell phone, computer, nor opened an email account. She is utterly fascinated with Tunepal “I’m sure you’re getting emails every day saying how much folks love your tunepal site and iphone app. I have the app and LOVVVVVVVVVE it! I use it every day. Awesome awesome awesome! Getting a lot of use out of this app now. Everybody I have told so far is very impressed.” It’s pure magic. Thanks a million for having made this diamond and share it with everyone. If there was a God, I’m quite sure that he would have you blessed ! I just wanted to thank you for the great idea and the great job you’ve done with Tunepal. It’s an excellent and very useful tool. Just what I whished for quite often. I am really impressed with the app. It was 100% correct in identifying tunes when I played them on flute or whistle. Having worked in a previous life in ultrasonic testing of materials, I can appreciate some of the problems involved. Thank you, Tunepal!!! You’ve saved lives!!!!!! Fair play to Bryan it’s a wonderful App I have learned lots of tunes from it and Names of Tunes as well Amazing! Congrats! I must be at least 30k of the tune searches 🤔☺ I use it so much. I love it
