About NumberPal

Rudhen-Electronics proudly presents NumberPal as the world's first easy-to-use number logger - in the broadest sense - for the Android platform.

NumberPal can be: just a number, a money amount, a mileage, a date or time, a temperature, a weight or distance, the numbers on dice or a roulette, but also a PIN code or password. We even support short texts.

The application opens with an index page and further one page per number. Each number page contains a description of the number and its value. Historic values are also kept in the database and can be visualised with a simple swipe-upwards action.

As NumberPal can also be used to store PIN codes and passwords, the app itself is also protected via a PIN code - for the normal items - and a password and AES encryption for the items that you tag as so-called Secure Items.

The first time

The first time after installation, NumberPal asks to accept its terms and conditions. There are no surprises in them but we insist that you read and accept these terms and conditions to avoid any issues afterwards. Further use is very intuitive.

Index Page

NumberPal provides a nice one-page overview of your current numbers. How many numbers are shown depends on the user rights. If more numbers are desired, then the user can buy more number pages from our NumberPal shop, with blocks of five.

Number Page

Each number has its individual page with on the upper half the description of the number and on the lower half its current value. Swiping left/right takes you to the next/previous number.

Page History

NumberPal keeps the history of each number in its database. By swiping upwards, the number history is shown. Swiping down returns us to the Number Page. How many history entries are shown depends on the user rights. The user can, for once, buy off the history limit from our NumberPal shop.

NumberPal Shop

The NumberPal allows to buy more user rights and to get rid of the advertisements.

Data protection

We understand that the data that you store in NumberPal can be very important. To support that, a back-up and restore system is in place with which the user can backup and off-load his data to a PC.

Pin Code

The collected user data can be highly confidential. Therefore, NumberPal can also be protected with a 4-digit PIN and a password for the really secure items.

AES Password Security

For the real confidential information, NumberPal has an extra level of security via a password mechanism. Also the database for the numbers tagged as Secure Items is encrypted with AES.

Social Media Sharing

Page sharing on all the popular Social Media sites can be done with a few button presses.

Integrated support

NumberPal has done its utmost to create the best user experience. Examples are our integrated context-sensitive help system, user tips and a news message facility from us to you.
