I have seen both sites, which are CloudKit and parse, also i have been read the articles as well about the comparison. Still i am not clear of that which is the best backend platform for mobile apps. I am looking forward your answer only for mobile platforms, it can be android or IOS.
Also i need to know about the performance and capacity allocation on each level.
First and foremost CloudKit don't quite support cross-platform. It generally only works with iOS. On the other hand, Parse support cross-platform. From your question, you seem to want to go for both iOS and Android. So for me to answer this question I would say Parse.
For deeper details, this link should tell all you need to know.
UPDATE:
ClouldKit now supports web services API.

where can I find detailed comparisons of the trade-offs in using one or the other?
I presume react native will use the iOS and Android SDKs which will yield better operability, performance, support, and features. Is this true? Where can I find documentation describing this?
As the heavy lifting is done natively by the browsers when using the OpenTok JS SDK, I would not expect much of a performance difference between the two.
I would consider the target audience and what mix of technologies you are using to build your application to be the important question here.
If your application's primary use-case is for mobile users, perhaps going react-native or even native is probably the way to go.
If your application is primarily web-based and you expect the target audience does not wish to install an app for it, then the OpenTok JS SDK might be the better solution.
The readme.md at https://github.com/NativeScript/windows-runtime says that the Windows runtime for Nativescript is in proof of concept stage, and then lists what I understand to be very deep language features that are not implemented yet.
The tone on the https://www.nativescript.org/blog/nativescript-runtime-preview-for-windows-10 announcement seems a bit more enthusiastic about the current feature set.
Being able to use Nativescript on Windows Phone (and any other platform) is incredibly appealing.
TJ, a core team member, recently posted on the forums about this:
Hey #NezzaGrey,
Thanks for reaching out, and awesome that you’re liking NativeScript :smile:. >Straight to the point though—we’re not actively working on UWP support because >1) it’s a ton of work to add a new platform and commit to supporting that >platform indefinitely, and 2) we’re not seeing nearly enough demand from our >community to justify taking on that work.
That doesn’t mean that UWP support in NativeScript will never happen, but it’s >not coming in the short term because we’re just not seeing the demand. That can >always change though. I’d encourage you to add your use case to the GitHub >issue open for adding UWP support in NativeScript: >https://github.com/NativeScript/NativeScript/issues/254. Yes, the issue is >somewhat ancient, but we really do pay attention to well-thought-out comments >during roadmap discussions.
I’ll note two other things. First, our initial work on making a Windows runtime >is completely open source and available on GitHub: >https://github.com/NativeScript/windows-runtime. We’d love to have community >?>help to make the new runtime a reality.
Second, one option you have is to build your iOS and Android apps with >NativeScript and Angular, and to use our code sharing approaches (see ?>https://www.nativescript.org/blog/code-sharing-between-web-and-mobile-with->angular-and-nativescript1) to share your Angular code with other apps. You >could take that approach to share Angular code between your NativeScript apps >and your UWP apps if you use something like Electron. This approach isn’t >ideal, as you’d probably prefer to build a completely native UWP app, but it’s >something to consider if you’re open to using Electron.
Anyways, hopefully you found some of this helpful. If you have any other >questions feel free to follow up.

I wonder why none of the Xamarin Prebuilt Apps at https://www.xamarin.com/prebuilt support both iPad and iPhone? They all have the same design on each resolution. Especially Apps like 'Acquaint' would be perfect on iPad to have the contact list on the left and the details on the right. But instead it just has the same design like the iPhone Version.....
Are there any reasons why Xamarin does not offer samples with different designs depending on the client resolution? Are there somewhere else some examples?
Many thanks!
You might want to take a look at our Creating Mobile Apps with Xamarin.Forms Book First Edition by Charles Petzold.
I work on the same team as Charles and I know it's a topic he's covered in detail. The full book should be available soon too.
BTW, we are looking into creating some detailed, annotated cross-platform app samples that do all the goodies that a typical modern app would be expected to have.
I do not know of any of the stock Xamarin examples that use OnIdiom, but it just a matter of time to code them...hahahah, always just a matter of time and code. (I'm sure the Xamarin guys can chime in on this one):
Xamarin.Forms.OnIdiom Class
<OnIdiom.Phone>Vertical</OnIdiom.Phone>
<OnIdiom.Tablet>Horizontal</OnIdiom.Tablet>
In terms of finding examples that use the Xamarin.Forms XAML OnIdiom I would search Github for OnIdiom, there a few OSS examples of phone/tablet switching floating around there as I used at least one as a template to do a quick phone/tablet prototype for a client.
I have some knowledge of basic PHP developing however right now I am thinking about developing a phone app. I do however have a bit of a conundrum in that I love WP7 and I have so many ideas for features which can't be done on iOS and Android, however at the same time I am completely aware that my target users (filmmakers) generally have iOS or android phones.
Is there a way I can develop the app, which I will get a developer to do rather than myself, with WP7 as the lead platform and then make a relatively simple conversion to the other platforms or do apps generally have to be completely reworked for each platform?
Also, just to though it out there, any idea of where to go to find a freelance app developer?
Thanks
James
I think you have a few options, but the first question I would have is: where comes the data from. Are you the owner of the data, and do you already have a datasource from where you can get the data from? If not I would suggest take some time to write a decent 'backend' from which the different platforms easily can get the data from.
Also all different platforms have their own pro/cons which you cannot share that easily. If you build a WP7 app in silverlight/xna, you cannot directly port it to a ios/android variant, also functionality will probably look/react different. You will need different solutions foreach platform with this approach.
Another option would be to use an platform like phonegap which can create a solution that will work on multiple platforms. (It uses HTML5 to get it work on the different platforms)
Build your app on iOS and android first, and when you have an app to base WP7 development then contact a developer that has made similar apps to yours.
I looked already and couldn't find anything good.
So a question is, are there any good web frameworks that would allow to easily develop GUI for the majority of high end phones? By this I mean
It would have to work "the same" on majority of high end phones (forget the low cost ones)
It would have to simplify the development and hide the ugly details from developer
Clear design and good documentation. Also some stability on the market.
The focus is on good looking and easy to make GUI. Javascript is only a plus.
So basically I am looking for something like jQuery or maybe ExtJS for phone development.
EDIT:
It would be a big plus if it could be consumed in Delphi
EDIT 2:
If it was not clear, I am looking for a web base solution that would run in a browser. So the target is HTML output and not native code.
To contribute to the subject. I found a question that has answers to such topic:
iWebkit vs. JQTouch vs. iUI
So there seem to be the following frameworks:
iUI
jQTouch
WebApp.net
iWebKit
Yahoo! Blueprint
JQTouch
PhoneGap
Sencha Touch
jQueryMobile
PhoneGap supports a wide variety of phones but it does so by making native (or interpreted I don't know) code to run on them, so it is a no go for me.
Yahoo! Blueprint supports a lot of phones also, but seems to need a special framework to run on. So also a no go.
jQTouch and WebApp.net look promissing, but they only support webkit based browsers. Yes these are in majority these days probably, but Blackberry for one has non webkit based browser and Blackberry is very important to me.
I will keep looking, in the meantime, don't be shy to contribute ;)
EDIT
Found this wiki about some frameworks. Most are embedded.
http://en.wikipedia.org/wiki/Multiple_phone_web_based_application_framework
EDIT2
I added Sencha Touch (www.sencha.com/products/touch) to the list as it was added after this post was created. They are the former ExtJS and now have the WebKit based mobile solution.
EDIT3
I added jQuery Mobile (http://jquerymobile.com/) to the list as it was added after this post was created.
Sencha Touch seams to be the solution. Since UniGui for Delphi/Lazarus already supports eye catching ExtJS it would be ideal if it extends to Sencha Touch. We will see.
I'm confused, do you want a web framework that runs on the web for phones (like jqTouch), or are you looking for something that will create native apps provides some amount of portability (like MonoTouch/C#)?
lightweight jquery-like alternative that works on android & iphone (& possibly blackberry & winmo) is xui, cfr. http://xuijs.com/documentation and http://github.com/brianleroux/xui.
edit: xui is more about javascript and less about a good looking GUI, so this might not be what you're looking for after all.
