Let me introduce: iSpark

First of all, thanks to the man/woman at Apple who reviewed iSpark in 48 hours! That's a new record for my apps, and I'm really happy about it being released before the new year .

This is what I wrote in the description on the Appstore:

"iSpark is a Particle Manipulator that lets you play around with 4 individual particle launchers. Each launcher can be customized using the sliders, you can choose size of the particles, growth, number of particles launched, speed of particles, you can even change the shape of the particles!

iSpark is the perfect app to play with during boring busrides, lectures or meetings. It's silent, fun and the result of a couple of minutes of tinkering is usually quite breathtaking.

Directly when you start the app there will be a tutorialvideo explaining the basics of the app, after that you're on your own, but you can always restart the app to see the video again.

iSpark manages 1200 particles when all the number sliders are at the far right, this means some pretty tough calculations for you iPhone/iPod, don't throw the app away if you get low framrate, try waiting for a bit or restarting the app. iSpark uses the accelerometer to affect the particles, try rotating your device to get different effects. It's also the perfect app for the holiday, celebrate the new year with 100% safe fireworks!"

And now to the nice part, it's free for NOW, it will be free for 2-3 hours so hurry up and download it now before the price is rised to the unhuman price of 0.99 $...

Download iSpark @ iTunes

Have a great New Year's Eve!

News and a Contest!!!

Good news first

As some of you might have heard, I'm working on a new app, this app will be released sometime in the beginning of 2010, I still need to work alot on the UI but all major functions of the app is already done.

This time I'm really pleased with my work, the new app is a "particle manipulator", which basicly means that you have control of a number of particle emitters :). So far you control 4 emitters and you can move them, change number, size, speed and alot of other varibles. You can also manipulate the color and shape of the particles for each of the emitters.

Contest

Yes I shall have a contest! I need help with comming up with a good name for the new app, if you got a good name for it, post it here in the comments or send it too me by mail at: joakim.rosenstam@hotmail.com.

The rules are the following:

* The name of the app cannot be offensive.

* The name of the app needs to be really awesome, not just "P4rticl3s".

Don't take the contest to serious, I will however reward the winner with... Well we have to see about that later, but the winner will most definitely have his/her name somewhere in the new app :)

That is all for now, more info will come soon, happy holidays!

iKeepScore version 1.5.1 is out!

Great way to start the weekend, my app "iKeepScore" just got through the appreview process and will be out on the AppStore toworrow! I will post a link to the app here when it's out.

This update fixes the bugs i talked about in this post, the update is free so if you are a proud owner of iKeepScore go update it!

Bugs.. Gotta love 'Em :)

Last night I recived a mail from a user of iKeepScore reporting some odd behavior. I booted up my version of iKeepScore, and sure enough the bug was there too. I went to sleep and first thing in the morning I started looking around the code, everything looked ok! Well, to be able to explain the solution I must explain how the app works.

What I have done is that I tagged each cell in iKeepScore with a number from 1 - 108 ( 6 players * 18 cells ) and in the

score calculating code I loop through the cells, adding the numbers together to a total score at the bottom. So this is was basiclly happend : one of the cells had the wrong tag...

So I decided to put the cells tag in the cell. The tag is basicly just a number. If you look to the right you will see two screenshots, the left one is correct, the right one is the one I got the first time. So the bug was this: instead of putting a 6 in cell number

6s tag, I had put 56 there.. and it got better... You can see that the cell where there are supposed to be a 42 is empty? Turns out I put a 41 in

that tag too. That one would have been

really hard for a user to catch, as it adds to the correct column.

I've updated the apps and sent in them to the Apple review team, expect the update to be released in about 3 weeks!

Denied again..

Just got another mail from Apple regarding my new app, looks like I resolved the issue on iPhones but not on iPods, argh... Well I'm fixing it right now, and hoping it won't take another 20 days to get some kind of respond from Apple :(

Small Update regarding the new apps..

Got my first rejection mail from Apple today.. I had forgot to put in an error message that should be displeyed if the user has lost connectivity... Well it took five minutes to put in, so I changed some other things to, I'm really exited about these apps. Sorry for all the secrecy about the two new apps, but I will provide more info when they're out!

That's all for now, have a great weekend!

iThinkQuick 1.1 is now ready for sale! And some stats!

New app in review!

I just sent in a new app for review, it's really 2 apps, one of them is a free version and the other one will cost 0.99$. I wont publish anything about what the app does before it comes out but it has something to do with news...

The free version will have ads in it, and the paid one will remove these. This is the first time I've been working with AdMob and the experience so far has been great, it was really easy to integrate with my app and get to function fully, so thank you AdMob for bringing an easy AdFramework to the table :)

Have a great weekend, I'll be back later when I get some new info about iThinkQuick 1.1!

iKeepScore version 1.5 is out!

iKeepScore version 1.5 passed the review process and is now ready for sale!

iThinkQuick 1.1 in review!

I just sent in an small update for iThinkQuick that fixes a small bug, added some new graphics, added some instructions and I added 2 more minigames. I know it's not alot of games but they really change the flow of the game. I also changed a few things to make the app run on devices with a OS older then the 3.0 version that's out now.

Expect the update to be out in 2-3 weeks ( around the 7th of september ).

This is a simple "minigame" based game. It holds 4 mini games that are supposted to be be completed in under 10 seconds. The 4 minigames are simple, and I'm planning to make more minigames to put into the game.

This game is supposted to be played with friends, alot of them! I got support for 8 players (not simultaneous though), you simply take turn on the singleplayer game.

I'm currently charging 0.99 $ for this app.

You can download the game here: iThinkQuick @ iTunes

iKeepScore

iKeepScore

This is my first app I ever created and sent to the AppStore, it's been out for almost a month and has about 1000 downloads. The price is 0.99 $.

The app itself is very simple, it's a scorepad for miniatuer golf. You fill in your name and then you start playing, putting the numbers in the cells after each hole. It also saves the scores when the app quits. Another feature is the "Shake-to-Clear" feature that many apps utilizes. Simply shake the device and all scorecells will be cleared!
