great app. Did you use any framework to build the app (I mean frameworks like sencha, enyos, etc)?

No, I didn't use any framework, but I am using Zepto library. I may remove zepto in the future as all these libraries are very slow on mobile. When I replaced $.html() with dom .innerHTML, rendering time improved by 50% in some cases.

By far the best web app I have ever used. Period. How did you manage to make it so fast? Also most web apps I pin to my home screen (not many) open in safari. how did you manage to get this to open it is own 'app'. It's not a part of safari, it has it owns icon in the app switcher. +1000 KUDOS I WILL be using this app a lot. edit: More kudos for being a Wolverine like myself. Go Blue!

Thanks,

I am not using any framework, and using vanilla JS as much as possible.

If you add these meta tags, it will open as app.
And this for icon

Impressive. I am going to use it even on my desktop. I think it you should make it a reader app (Replacement to Google Reader etc).

Ok, this is awesome. I can't believe no one else (including you) submitted this yet. Bookmarked. Love it.

Wow, good job!

But as you said, given that you didn't use any frameworks the productivity couldn't have been that great... Not to mention that it probably doesn't blend in with the native apps? (don't have a mobile with me right now, so can't test it)

this is an awesome insight. any chance you could share more of these lessons?

You should try it on mobile.

Well, I am not a designer so it took me while to get right colors, background, text sizes, layout etc. You can see my profile here. (http://premii.com).

Initial app took one Sunday. It worked on android browser and iOS. If I only had to make it work for iOS, it would ve been easy, but chrome on android took as much time as the whole app. Later found that there was a bug in chrome. They just fixed it like 2-3 weeks before.

It worked on WP8-IE10 without any special code. I didn't had WP, so I asked reddit/r/windowsphone guys and they told me it works great. Couple of redditors reported minor issues which I fixed.

I am not saying this is easy to do, and I will never advise anyone to user HTML5 if they have CPU intensive task and super complex animation/interaction. However HTML5 is the only platform that can help you develop simple app that works on all 4 mobile platforms (iOS, Android, WP8 and mobile browsers).

You're able to infer the answer to all those questions.

Relative to native. Slow for users. A typical non-super-dynamic app. Use common sense.
