There's a more extended writeup of some of the major changes/features at http://kivy.org/planet/2015/04/kivy-1-9%C2%A0released/ http://kivy.org/planet/2015/04/kivy-1-9%C2%A0released/

Congrats, Kivy team! I'd love to see reviews or performance benchmarks from people who've built using Kivy, but I can't seem to find much recent information. Can anyone help out? Thanks!

  Posts with no discussion don't count as dupes on HN (there's too much randomness in what gets attention for that to be fair). But there have been others: https://news.ycombinator.com/item?id=8181306 https://news.ycombinator.com/item?id=8181306.

are there any major apps written in Kivy and present on all the mobile platforms? or atleast on AppStore and Google Play?

  The only one was ProcessCraft, released years ago. Right now, it seems that peoples are shy to share their apps. We have a list on the wiki of what we have found + users contributions: https://github.com/kivy/kivy/wiki/List-of-Kivy-Projects https://github.com/kivy/kivy/wiki/List-of-Kivy-Projects But i'm sure there is more. Like this one: https://play.google.com/store/apps/details?id=com.nrtech.nrt8000&hl=fr_FR https://play.google.com/store/apps/details?id=com.nrtech.nrt... - Kivy is not referenced anywhere, but it's based on it.

  I like kivy a lot, it is very powerful and promising. The following should not be taken as harsh criticism as it may look: Kivy has two problems in my opinion, why it isn't used more widely. The first is the documentation, which while being quite extensive almost never tells the whole story, especially the many paradigms and details which are very different from other frameworks. Second is how hard it is to even achieve simple tasks (beyond putting a few buttons together). A good example is the almost dysfunctionally complicated ListView, which actually can't do that much. Kivy's widgets in general are lacking, and the visual design philosophy seems to be "ugly by default". This is really just my opinion. I think that the event and input handling is great, and the graphics library is very remarkable for supporting hardware acceleration to a python app on so many platforms.

    Documentation. A subject that is as important as the code, maybe more. We are internally always debating what does an user should known by default, and how. Both matters and depends of the target (noob, average, expert) or which approach first (kv based or python based). I personally don't know how to write a good documentation, except if it's just API documentation. But in that case, API is just not sufficient, as concept need to be explain as well. We have actually one big big big contributor named ZenCode who work behind the scene on the documentation, and constantly fixing our mistake / wording. I ear you loud and clear, wish to have a better programming guide / module documentation as well. About ListView... Let's say it's one of the Kivy widget that doesn't fit to the Kivy logic at all. Historically, i started a POC about it, then a contributor take it and worked a lot to have something that works for any sort of situations. And he tend up to something that cover lot of cases, but still bugs, and not easy to get it. Not to mention issue with performance. That's why i rebooted the ListView from scratch, and named it RecycleView (like RecycledView from android): https://github.com/kivy-garden/garden.recycleview https://github.com/kivy-garden/garden.recycleview The visual design was taken from Meego / Android in the old days. We might be able to refresh the theme one day, if we have somebody that can contribute to it (i mean a real designer, not a coder). I rarely use the default theme, always extend a widget to put the designer visuals i got on customers projects.

  Here's a list of apps on the App Store and Play Store: https://github.com/kivy/kivy/wiki/List-of-Kivy-Projects https://github.com/kivy/kivy/wiki/List-of-Kivy-Projects Around 50 on the Play Store. Only a handful on the App Store. Also, this list is not exhaustive.

  The RaceCapture app is written in Kivy, we support Android, OSX and Windows (hopefully soon iOS). Overall I'm impressed at how well 99% of things 'just work' across platforms. http://www.autosportlabs.net/RaceCapture_App_User%27s_Guide http://www.autosportlabs.net/RaceCapture_App_User%27s_Guide And our app is open source! https://github.com/autosportlabs/RaceCapture_App https://github.com/autosportlabs/RaceCapture_App
