Is your wallet overflowing with loyalty cards from airline frequent flier programs and hotel, restaurant and retailer rewards programs with AA Advantage, Border's Rewards or BestBuy Rewards Zone?

CardMobili is a mobile app that lets you store all those cards on your phone.   When you need to use one of your cards, you launch CardMobili, scroll down to the card you want to use and click it. CardMobili displays the car number and barcode.

The app worked well on my i776, although the barcodes looked too small to be scanable.  If the code is not readable you can always tell the clerk the number. Update: Pete Orange discovered that if press the OK key a second time when the card is on the screen to show the barcode full screen.

A downside of this app is that you have to use the CardMobili PC site to register for an account and to add loyalty cards.  I couldn't get the PC site to work properly with Opera Mini or Bolt so your really do need a PC. Hopefully the next version will let you do everything on the phone.

CardMobili was chosen as the best new mobile app at the AppCircus  competition at the Mobile 2.0 Europe developer conference held in Barcelona last week.  I was part of the panel of judges that chose the 10 AppCircus finalists.  The overall winners were picked by audience vote at the conference with CardMobili winning top honors.

This is an app for creating a daily journal or diary. Supports emoticons and choosing the day's "mood". Entries are organized by date and you can search the diary a particular word or phrase.

If you register you can archive your diary on UltimaSquare's website and view it online.  Warning: archiving deletes all entries from the phone. The option to view the web archive from within the app doesn't work as it tries to launch the browser which Java apps aren't allowed to do on iDEN phones.

You can view your archived diary entries at www.ultimasquare.com/diary/main.php using a PC or mobile browser. Online diaries are password protected by default but you can make them public if you wish.

J-Address, which is also called JKFriends, is a basic address book.  It has two fields, Name and Details which is a free form field where you can put the contacts, mailing address, phone numbers, email addresses, birthday, etc. J-Address is completely indendent from the phone's built in Contacts app and you can not make calls or text from it.

An open source personal expense manager with predefined categories  like food and clothes and the option to add new categories. There's an undocumented (and untested) sync option that is supposed to send a transaction file to Quicken, Microsoft Money or GNUcash on your PC.

Millilock is a personal organizer that combines an encrypted password keeper, a notes app and an address book. Notes have a "done" flag allowing you to use them as "to-do"s if desired.  The address book includes several fields missing from the Motorola Contacts app including company name, street address, notes and two phone/email fields. Unfortunately it doesn't seem to be possible to make a phone call or sent a text message from the address book.

Millilock is supposed to be able to synchronize your information between the phone and a companion PC app.  I haven't been able to get the synchronization to work.  I might be doing something wrong, but I suspect that the sync feature is incompatible with iDEN phones. The lack of  synchronization is a disappointment but not a surprise as none of the other password or notes apps I've tried on my i776 are able to synchronize either.  Even without synchronization Millilock is a useful app.

Calc is a powerful programmable scientific, statistical and financial graphic calculator with 19 digits of decimal precision and over 200 functions including complex arithmetic, matrix and vector calculations , date arithmetic and unit conversions.

Calc  works like the classic HP calculators using RPN (Reverse Polish Notation).  There is definitely a learning curve to using a RPG calculator, you will probably need to study the extensive manual to be able to make any sense out of this calculator.

The keys work as described in the manual with one exception: The center OK key doesn't work, you need to use the green Call key instead:

An alternate to ExpApp for expense tracking and money management. Money Manager lets you enter expense items and assign them to categories. You can edit the categories and add new ones. There is a nicely formatted monthly expense report showing expenditures by category. You are supposed to be able to email a copy of the report in CSV or Excel format but that function always gives an error on my i776.

I've been using Mini NotePad to write quick notes on my i776.  At first I really liked it but then I discovered a nasty bug. When you save a note in Mini NotePad you have to give it a name.  Then should let you easily find a specific note by name in the program's list of notes. Unfortunately, if you go back in and edit a note its name gets changed to "Mini" when you save it! There is no way to rename notes when this happens either. Before long I ended up with multiple notes named "Mini" and had to open each of them to find the one I was looking for.

That bug prompted me to switch to GBJotPad which doesn't have that bug, in fact it doesn't make you name your notes at all. It lists them with the first few words of each as the title. gbJotPad, like Mini NotePad and unlike all the other notes programs I've tried, lets you suspend and resume the app without loosing your unsaved document.  The only thing lacking in gbJotPad that Mini NotePad has is the ability to enter a line break and gbJobPad doesn't.

I've looked at several tip calculator apps and GeoTip is my favorite.  You enter the total bill, tax percentage and desired tip percent and GeoTip deducts the tax from the total and calculates the tip on the total minus the tax.

The thing that sets GeoTip apart from the other Tip Calculators and makes it my pick is that it lets you save the tip and tax percentages so that you don't have to enter them every time.

GeoTip tip: To enter a decimal point on iDEN phones press the "1" key twice.

GeoTip is free, the author asks you to send him a donation if you like it by using the PayPal link on his product page.
