Greetings to all developers.
Hello!
I'm software developer from Russia, and made one very popular app in local market. Very soon I realized that I need an ability to give licensed version of app for my friends or reviewers or someone else.
Unfortunately AppHub doesn't provide such functionality(private distribution is pain in ass), so I created a webservice for myself.
After two days I realized that it may be useful for other developers, so here it is:
promo.g33k.ru (here I wanted to post url, but I can't due to low post count. You may find it in my profile->interests)
Now it has:
- JSON/SDK with RSA1024/SHA1 sign for additional security checks
- Binary SDK available
- Russian localization(if anyone cares ) (btw, if you can help translating to other language(s) or correct english misspellings - i will appreciate this).
Now this service works in beta mode.
So for developers I have two questions:
1) Is such service useful for you?
2) How to develop it further, in which way?
Not yet clear
I am sorry, but after reading your post and also checking your website I am still not sure what you offer. For me there is just not enough information to understand and then judge the usefulness of your service.
Maybe you could give a step-by-step scenario: Dev does this, then interested user does that, dev then this ...
Ok, I'll try to describe a little more details:
1) Developer wants to add capability of promo codes in his app(to give some specific users full licensed app).
The first problem is that developer need his own server for checking of promo code validity(hardcoding is not an option, of course).
2) So, Developer registers in my service, add his app's guid to his app list and create a promo code for specific app via web.
3) Developer adds support for promo codes in his app by:
a) adding an text box for user to enter promode
b) adding a web request to specific URL for promocode activation
c) adding to his license check web request for checking is current user activated a promo code.
Benefits for developer:
- Add support for promo codes without owning a server.
- Simple way to give full version of program to friends
Benefits for users:
- User may found promo code for specific app somewhere and use it to get full version of app in simple manner.
Benefits for reviewers/portals:
- Developers can easily give promo code for reviewing purpose or as giveaway for news post.
Clear now
Thanks for the additional info, now it's clear
Well yes, sounds useful. Properly implemented is probably really easier than Microsoft's "closed beta" mechanism, and of course can be used for other, non-beta apps as well.
The icing on the cake would be a "frame application" as sample code that basically does nothing more than asking for a promo code and then check against the list of valid codes on your server.
Sounds intresting but how do you ensure security?
chabun, I thought about security and situation is same as with default checking for trial - there is no security Man-in-the-Middle and direct cracking of xap will work, and there is no way out. I could use RSA signing for MitM, but still cracking of xap is very easy option today, so no one really interested will try to use MitM. When WP8 SDK will be out(I believe it will be in several weeks) - some developers may implement trial checks in native code - this will be much harder to crack.
As for server part there are following possible problems
- App's ID squatting(same as domain, someone else could reserve developer's app's guid). Don't know yet what to do with this, may be think about it later when this happens?
- Promocode's for App ID bruteforce - could be easily avoided via server throttling, if this ever happens - i'll add such checks
- Server DDoS - every webmaster's nightmare, I hope this never happens(or my Amazon AWS will pour my purse empty
rbrunner7, nice idea, I'll add a sample app as soon as possible on site.
This looks like an interesting concept

Yop, you can never avoid direct cracking... However, RSA signing would be good I'd say as it will avoid MitM - with MitM you could create simple tools which can be used by every noob outhere. Cracking xaps requires some skill and it will need an unlocked WP7 as well.
I can see this working i have been thinking about something similar also. You can encrypt the data on device before sending it off to the cloud, you can than verify the encrypted data with a password and compare it to the codes registered on the server. Than link a code to a certain device id (once the code becomes 'registered') if a certain code is already coupled to a deice id and the device is not the same than the app will jump back into trial mode. Otherwise one can use the paid mode.
This can defenetly work and will prevent reselling th codes. Although it requires a server. And users can still hack/patch the app ofcourse but that will require an unlocked device so I should not worry to much about it.
Also to prevent spoofing you can frequently check with the server if this device is legitetmately registered.

That's what I thought of... private/public key
chabun, so, for example, how about following scenario:
for each developer server creates public/private key pair.
when checking license on server: if success server encodes userid with developer private key
when checking license in app: server response decoding via public key(hardcoded in app) and comparing to userId. if ok -> licensed.
You might want to ask @ngreader guys on twitter. They do have this concept implemented in their app.

I'm not sure if it would be good to encode the request to the server as well but otherwise it sounds really cool now... I'll use this service when I need this (and tell my friends about it)
Here is one way to do it http://stackoverflow.com/questions/599837/how-to-generate-and-validate-a-software-license-key

Well, what they suggest is not as good as diverofdark's service which is a lot more secure and still easy to use for the customers...
Greetings everyone!
Today I updated promo.g33k.ru, now it has:
- more detailed about page,
- SDK now includes RSA1024/SHA1 sign for additional security checks
- Binary SDK available
- Russian localization(if anyone cares ) (btw, if you can help translating to other language(s) or correct english misspellings - i will appreciate this).
- Many minor bugfixes.
So, from now this service works in beta mode

Thanks! I will check this out
Hey diverofdark
It would be nice if you update the first post in the thread with all information. That's the way it's usually done in the forum.
A possible user (here dev ) can read it and without having to browse the whole thread, he can use your promocode service...
Thanks for mentioning it, I updated the first post.
I don't like filesharing-sites and so on...
So i give free webhosting space for gio devs!
What do you get:
-Unlimited bandwidth
-2GB disk space
-100/100mbit internet connection(12Mb/sec download and upload)
-A subdomain on lemminggaming.org
-AD-free
-You can upload ROMS and websites(PHP&MYSQL allowed) with a FTP client(filezilla)
What do you need to get it?
-PM me with your email
-in 24h you'll get login details and instructions howto change password and howto upload files
What can you do with this offer?
-Host a full website(wordpress, drupal, phpBB EVERYTHING that uses php (+mysql) is allowed, also static HTML pages are allowed ofcourse)
-Host your roms and give direct links
I had it, but the link got changed or something, couldn't use it anymore unfortunetely
Host online
Sorry, didn't reply to PM's, send a PM again with a email if you want free webhosting
I got a special server online for it, special for gio devs
Just curious to know... Do you need that new users subscribe with your referral code to improve your gain? (i'm not attacking you)
For something under 5GiB, you can always use GitHub pages or similar free services from git hosting platforms. The only requirement in most cases is that your website source repository is set to public. Certain CMS even exist for managing such hosting using a convenient UI.
PREMISE
see mockup attachment. fyi, some minor details are left out to protect the premise.
the purpose of the app is to create a countdown clock. and we intend to have different sponsors.
FRONT-END REQUIREMENTS
when the clock expires, it will have beep and vibrate.
to make money, when someone brings up the app on their phone, they would see a coupon from a sponsor company. and upon the launch screen, if the person likes the coupon, they can request to have it e-mailed to them. there's two options to have at this point. a) the app sends me (the app business owner) an e-mail confirming that this individual has requested this coupon. and I'll e-mail it to them whenever I get a chance [but this could get messy if there is a ton of users] b) the app somehow automatically send an e-mail right then and there to the individual [this could be a Day 2 project].
regardless of whether or not the visitor has requested the coupon e-mailed to them, when they click the "ENTER APP" button, they should be transferred to the APP SCREEN.
BACK-END REQUIREMENTS
a. we will NOT store any customer data or e-mails or anything else. we will simply generate a one-time e-mail to that address and that's it.
b. we would like to track a) how many downloads so we can tell potential sponsors b) how often people use the app and how long it's open on their phone for.
c. needs to work on android, IOS and windows phones. we do not care about tablets or computers. smart phones users will be 99% of our audience.
d. we need some sort of back-end or web interface where I can enter in new sponsor names, logos and coupons.
QUESTIONS
1. I'm not going to learn to build this myself. i have no knowledge of how to build one and don't have the time to learn. i plan to hire an overseas freelancer through odesk.com. what program should I ask they use to build this? I've heard terms like swift, xcode, ruby on rails, twitter bootstrap, etc… ideally, is there one go-to popular program that creates a cross-platform compatible app? my fear is that if I have to drop a programmer in the middle of the project and pick up another, will the new person be able to pickup where the last guy left off?
2. how would I go about changing the coupons? and changing the sponsor banner ads? would there need to be some sort of web interface? would I need to purchase a website and hosting account and have some functionality built there? is there some dashboard somewhere else?
3. how big scale a project is this? roughly how many hours should this take a COMPETENT app developer? seems to me like one of the most basic apps you could build but what do I know.
4. at what point does an app get submitted to google play? apple store? windows whatever they have? or do I even need those entities or could I just let people somehow download it from a website? if so, what would I be missing out by not getting it listed under those marketplaces?
5. anything else I have not thought about that I should be aware of?
please advise. thanks in advance!!!

Hi i have read your long query,The app which you described and checking out the mockups seems to be pretty less complicated and i will give you some answers for it.
1) The best thing to do is make an app in popular cross platform frameworks better use html5 frameworks such a sencha touch,jquery mobile etc with phonegap. Look for developers in this category.
2)Changing the banner ads and coupons is simple.Just host that in your server,app will load those ads and banners whens it loads for the first time ,we can refresh the content later by periodic service calls
3) its a small scale project .Just building the app alone will take atmost 30 hours including creating for 3 platforms and excluding testing.
4) its always better to upload the apps their respecttive stores.Apple wont allow apps to sideload fro other sources.For getting listed on those stores you need to get developer licenses 100$ for apple store,25$ for google play store etc
5)Just be aware that the app should work on all ost of the devices ,gives timely updates etc
also you can track the number of downloads from the respective stores,also you can include some analaytic sdk like flurry etc to get the details like "how often people use the app and how long it's open on their phone for".
i am an Cross platform app developer.If you are interested we can talk in Pm. hope i helped
i have some application source code which the author is displaying in github.
i just need modifications for it which are mainly removing features.
I have the exact instructions that i want edited.
The application is like gallery where users post images or videos.
Text me and i will send u the app files link from github.
budget is less then $50.
and wil be paid after completion of work.
if anybody is interested in doing this. Message me. we will talk more there.
