iOS app plans for year 2011

It’s that time of the year again, the time for new year’s resolution and planning. The past year has brought interesting addition to our family: our baby girl “Youyou”. On business (or iOS app) side, I joined the iPhone (iOS) developer program in July (paid the $99 annual fee), and released the first app myNestEgg ~ the retirement calculator in middle Sept. The second app collegeFund ~ college savings calculator shortly followed. The results exceeded my expectation, as I released a few updates to fix the problems/add features. Meanwhile, I went to the Voice That Matters – iPhone developer conference (Philadelphia) in Mid Oct. Meeting iPhone developers and learning new things are the main take aways there.

For the new year, I am thinking of two things: 1) Continue to improve the existing apps; 2) Work on an iPad version of retirement savings planner. I don’t have a definite timeline yet, as I still have a day job, but I hope to release the iPad app before the iPad 2 arrives.

myNestEgg v 1.3 released

This is to fix a show stopper problem in v 1.2, as pointed out by one of the users. The problem happened after a user used the keyboard to input data (dismiss the keyboard by tap background), the app will add a comma to “beginning savings” and “salary”. This causes confusion and mis-calculation down the road.

The problem is fixed now in v 1.3. The user needs to update the app to get the fix. In some cases you may need to re-enter the “beginning savings” and “salary” if those numbers are no longer correct in the app. Please let me know if you have any problem.

I am sorry for the inconvenience it may have caused, and wish all a good holiday.

myNestEgg 1.2 released

Known problem in version 1.2
(11-21-2010) I received a user bug report this morning: the calculation results is not right due to the extra comma separator in “beginning savings” and “salary”. I fixed the problem this afternoon and submitted the binary (version 1.3) to App store. Stay tuned.

myNestEgg_bug_1

What’s New in Version 1.2
1) Add new icons for the tab bars (the 3 bars at the bottom);

2) Add “shake” function to “Settings” tab bar. When at “Settings” tab, if the user shakes the phone gently, the rates will reset to default values: 7% annual investment return, 2% annual inflation. Note the user still needs to tap “Set Rates” button to make the rates take effect.

3) Fix the minor problem where the inflation rate picker moves when the user switches to the “settings tab”. Note this behavior has not affected calculation results.

I just found a bug shortly after the release. If someone reports the problem to me, he/she will have the opportunity to win the $25 Amazon gift card.

collegeFund free for now at iTunes App store plus more

(Update Dec 16, 2010) Free again for limited time (until Dec 25).

What is it?
collegeFund is a college savings calculator iOS app (iOS 3.1.2 or later) I released a while ago (Oct. 5 to be precise). Link to iTunes App store here. For a limited time (this annual benefits enrollment and holiday season), I am making the v 1.0 app for free. I will end the promotion as soon as the v 1.1 approves.

collegeFund_iTunes_store_2010-10-27

Why free?
I am out of mind :-) Actually I thought about this before the release. Over the years I came to believe college education is a prerequisite for many things in life: the college experience, the knowledge learned and friendship formed in college, last but not least, the skill of “how to learn on one’s own” and a path to entry level job. For me and my wife this is not possible without the sacrifice of our parents. This March our baby daughter was born, and we enrolled in a college saving plan for her shortly. We are just trying to repeat what our parents did for us.

In the same spirit, we would like share this little app with all the hard working parents.

Is it really free? Am I ask anything in return?
Yes. If you are happy with the app, you can help me out by

1) send me feedback, including write reviews on iTunes store, good reviews only :-) ; send me unpleasant reviews by email (uudaddy no spam AT gmail DOT com).

2) I do have a paid app, myNestEgg ~ the retirement calculator at App store. So if you have an extra dollar(s), you can buy or gift this little app during holidays :-)

What if you already paid for the app?
First I want to say “thank you”. I can either refund you the 99 cents, or give you the myNestEgg app.

What if you already bought myNestEgg too? We are not entering an infinite loop here, let me know and I will send you something, for your patronage.

myNestEgg 1.1 released yesterday

I know, I know, I am a little late making the announcement. But I was fighting a small battle.

Anyway, the latest and greatest is here. It has all the goodies of version 1.0 plus the following new things:
========
Fix the problem in “email results” when income_ratio is larger than 100%, the email results shows 100%. Now it shows the correct number.

Set default inflation rate to 2% (was 1% before the change); set default investment return rate to 7% (was 6% before the change). We believe the new numbers are more realistic numbers.

Change the calculation of inflation adjustment to fix the “divide by zero” problem in some cases.

At philadelphia voice that matters iOS conference

I am at Philadelphia now. I came here for the VTM iOS conference. Took southwest Air from STL this evening, arrived phl slightly after 10. Planned taking the shuttle, but could not reach the guy per his instruction. Took train to market east/Philly conference center , then called a taxi to hotel. Saw quite some people on street on the way to society hill Sheraton. It seems free AT&T wifi only works on my iPhone, not MacBook. So I settle on iPhone for tomorrow conference info and how to get there.

I also wrote this post via wordpress iPhone app. It requires wp 2.9 but my Stlplace blog was still at 2.0.2 :-(

Oh, by the way, it seems apple fixed myNestEgg app update (1.1) stuck in “upload received” status. It’s in “wait fore review” mode now. This update will fix some of the bugs.

Why I created myNestEgg retirement calculator app?

More Q&A about myNestEgg ~ the retirement calculator app

1. Why do you create yet another retirement calculator app?
I understand there are quite a few retirement calculators in the App store. Some are free, others are not free. MyNestEgg belongs to the latter category. My goal here, as I said the the product description, is to provide a simple and easy to use to calculator retirement savings/income. It shows the “saving progress” and “income ratio” which combined give the user an idea about where she/he is in terms of saving, and what income level to expect when she/he retires. Also the input data is saved on your iPhone, so as the user runs this app from time to time, she/he can get an idea about how the retirement savings account does over the time (so that she/he can act accordingly).

2. Does it support language other than English?
The app use English only at this time. However, as I explained in the support page, the user can adjust the “regional format” to get the local currency.

3. I don’t have iPhone, so…
The app can be run on iOS 3.1.2 or later powered devices, which includes iPod Touch and iPad besides iPhone.

I saw some useful web based calculator, such as this one created by FINRA. One limitation is they don’t save the data, so you may want to write down the results (or better yet save to Google Docs) after doing calculation.

Also, I am consider porting (creating) the app for Android, if there are enough interest to justify my effort.
