There are times where the password of a PDF document is tied to your personal information. For instance, if you have investments being managed by an investment company and they give you a quarterly document as a PDF document. These documents are usually confidential so they protect it with a password that is tied to your name, birth date, phone number, account number, and whatsoever. Remembering a password that hasn't been personally set by you is difficult to remember. Moreover, it gets difficult to remember if the password format changes or the document comes from different groups having their own format of assigning password. Things get inconvenient and this is what this application is for. This application is not meant to break an encrypted PDF document. The application simply remembers the passwords you use to open PDF documents. The next time you open the document again, it won't ask you for a password again.

If there are stuff that we would like to have the best value for our money then it would be on grocery products. These are products that we frequently buy because we need them on a daily basis such as food, house hold cleaning materials, health care, and the like. There are many grocery stores (including online) that offers these products and they come in different size and prices. Before deciding to purchase a product, we only not think of its given cost but also other costs like taxes, sales discount, fare/gas to commute, shipping fee, bulk buy discounts, price per unit and many more. Yup, it gets confusing as it adds up so we just end up buying whichever and wherever we see the product first to get it over with. Although if we think about it, we can't really escape these purchases because they are "needs" and we want to have the most of it with the least cost. So here it is, we built a mobile-application that would help save money. It's a simple stand-alone application wh

Yes, this is a yet another file transfer application. However, we did not build this application to intentionally re-invent the wheel but rather because the lack of application where you get stuck in an unfortunate scenario. We made this light-weight, portable, and dirty file transfer prototype. To make it portable, we developed a Windows and Java version.

Right, this is a yet another Expense Manager application. Have you used one? There are actually a lot available from desktop to mobile applications as you see in Android and iOS. However, one of the biggest problems I had with these expense managers (especially the free ones) is that they are so fully loaded with features (and unrelated features) that we don’t even bother to use and understand (not unless you are the accountant type of guy). It is great nowadays that we can carry this kind of apps on the go (because mobile phones) since we can record our spending habits right there right now. However, having a fully loaded accounting features and technicalities makes it difficult to use for an average user. So what is an average user? I for one is an average user, all we know is that we have cash, we spend some of it, we save some of it, and at the end of day we would just like to know how much and where you spend it.

So you've been a long time user of the Windows OS and one of things that you always do is to keep your files and folders organized to keep yourself productive by efficiently storing and retrieving them at a later time. The problem with Windows is that they never added a feature for users to allow them to add additional information to a file or directory. There are many reasons why this feature is needed especially for a person who manages multiple files and folders. We thought of creating a simple utility program to solve this problem where you can tag notes to your files or folder.

Genealogy is all about family line, more of like the family tree. If you've seen a family tree, you'll be able to trace your ancestors and other people whom you are related with. The experience of tracing the family is pretty much difficult. You will have to rely on strong memory, otherwise you will have to write it down and preserve those papers to be passed on to the next generation. Nowadays that we are in the digital age, software developers created app to do this so that records will be stored digitally thus it makes it easier to process stuff. The problems with those software today is that they run on computers like your typical desktop and laptops. During social gathering, you're not going to expect yourself bringing with you those devices and entering their names to the database. We're lucky today that smart phones have been more powerful than ever that you can do such stuff. So we thought of creating a simple light-weight mobile android application that would do this for you.
