Here are the apps that I was not able to find on the master list on page 1 (or maybe I'm not searching the right text), and they definitely should be on the list. I hope to see them on Jolla someday :-).

• video editor (should be as easy to use as iPhone's built-in video editor)
• ebook reader with support for epub, Kindle (azw, kf8), lit, and mobi
• comics reader with support for all the popular formats (cbr, cbz, cb7, cbt, cba)
• WordNet dictionary
• AED (Advanced English Dictionary), or something as polished as this Windows Phone app
• CamScanner, Genius Scan, or something similar to take photos of documents, automatically color/contrast correct and align them, noise reduce, and convert them into PDFs
• planetarium app similar to Google Sky Map
• famous quotes/quotations app
• IMDb client
• Wikipedia client
• Kayak client
• Wego client
• SkyDrive client
• Google+ client
• Google Hangouts client
• LinkedIn client
• Gmail client
• Yahoo! Mail client
• Tincore game keys mapper
• Amazon store app
• Craigslist app
• Groupon app
• clipboard manager app like Clipper+ or Android
• bubble level app
• SPL meter to accurately measure decibels
• find-my-phone app using GPS with ability to remotely lock/wipe phone
• 360 degree panoramic capture app similar to Photosynth

I apologize if any of these apps have already been mentioned deeper into this thread but did not make it onto the master list.

Cheers,
Tom
