Panecal has functions such as editing and recalculating calculation formulas entered in the past, as well as the capability to use variable memory to only change specific values and do calculations.

A cursor is displayed on the screen, and you can tap the screen or push arrow keys to quickly move to the location you want to edit. Panecal allow you to swipe to scroll through formulas, as well as copying and pasting using long tapping, which makes it a strong and flexible application with an intuitive user interface.

[Main functions]

- Move the cursor by tapping and swipe to scroll through the screen

- Copy and paste

- Can select from a history list of formulas calculated in the past, edit them, and recalculate

- Can calculate binary numbers, octal numbers, decimal numbers, hexadecimal numbers up to 32 bits, and do radix conversion

- Can use M+/M- memory functions and 6 types (A-F) of variable memory

- Arithmetic operations, inverse trigonometric functions, logarithmic functions, power functions, power root functions, factorials, absolute values, and percent calculations

## scientific calculator

NHN-1 is a free advanced engineering and scientific calculator with a transparent widget that has fractions and percentage:

•A resizeable widget with arithmetic, percentage button, and fractions.

•Expression (formula) based input.

•Fraction input and output with conversion to proper fraction, mixed fraction and decimal. Even the quadratic or cubic root functions, for instance, will return fractions when the answer can be written as a fraction.

•Full history with buttons that load old results, in case you need to start over from a previous point.

•Unlimited memory slots that can be named and are always displayed on screen.

•Multiple input fields except on small phones. This let's you do short side calculations without losing your place.

•Pre-packaged functions for quadratic equations as well as many geometric formulae.

•Buttons that store user defined functions that are created by binding an argument to a binary operator.

•Visualization of multivalued complex functions (roots, inverse trigonometric, logarithm)

•Visualization of quadratic and cubic functions

•Visualization of angles returned from inverse trigonometric functions.

•Complex numbers are very easy to work with, and all functions work with complex numbers where they are defined (inverse hyperbolic cosine, for instance).

•There is a fourth layout for small phones that is not shown in the screen shots.

•A unit conversion utility that lets you build arbitrary composite units. Conversion factors are written to the history, so you can bind the factor with multiplication to do the same conversion many times.

The layouts are designed to be ergonomic for each of four device sizes in portrait and landscape. Here are some examples of what we've done to make the calculator easy and speedy to work with:

•On small tablets in landscape, the keys are split so you can operate the calculator with two thumbs.

•On small phones, the numeric keypad is right under your thumb when holding the device with one hand.

•Square root, square, inverse and negation are all close to the numeric keypad.

•On small tablets, the long "NHN-1" button is a gesture recognizer that lets you scroll the six input fields with your left thumb. That way you don't have to let go of the device with your right hand to click an input field.

## SIM Card Manager

SIM Card Manager is a very tiny (only 57 kB!) tool that reads your phone SIM card and displays many useful information:

- Phone type (GSM, CDMA etc.)

- Phone number (if available)

- IMEI of the device

- SIM state (SIM absent, network locked, PIN required, PUK required, ready)

- SIM country ISO code

- SIM operator code

- SIM operator name

- Network type (GPRS, EDGE, CDMA, UMTS, HDPA etc.)

- Network country ISO code

- Network operator code

- Network operator name

- Network service state (registered to network, network not available, emergency numbers only, service powered off)

- Network selection status (automatic or manual)

- Roaming status (active or inactive)

- Voice mail text ID

- Voice mail number

The application also lists contacts stored on the SIM card and allows you to do several operations with the selected one (call, send SMS, share, copy to clipboard, copy to the phone, delete from SIM card etc.).

As an addition, SIM Card Manager lists phone and Google contacts in separate tabs as well.

To access more features, please use a long click on any listed item.

Thank you for using SIM Card Manager and feel free to check out our other applications.

Explanation of permissions required by the application:

READ_PHONE_STATE - to read information from the SIM card

READ_CONTACTS - to obtain the SIM card contact list

WRITE_CONTACTS - to delete the selected contact

READ_CALL_LOG and WRITE_CALL_LOG - for some reason, these permissions were added by Google after uploading to Google Play and SIM Card Manager does not use call logs in any way

## Digital Clock Widget

To use this widget:

- Long click on an empty space of your home screen

- Select Widgets

- Select Digital Clock 4x1 or Digital Clock 2x1

IMPORTANT! If you use Memory Booster or any other kind of task killer, make sure that Digital Clock Widget is on its white list or it will not work properly.

If the widget stops working after upgrading to a new version, please uninstall and reinstall!

Digital Clock Widget is a very tiny (only 90 kB) home screen widget that displays current time, date, day of week, alarm clock and battery level percentage (+ battery temperature). It contains 2 versions:

- 4x1: You can click the time (to open an alarm tool), date (to open a calendar application), battery level (to open the battery usage screen) or settings icon.

- 2x1: You can click the time to open a context menu with alarm, calendar, battery and settings items.

The widget also contains a cuckoo clock that notifies you on every full hour. The cuckoo can be easily activated/deactivated or set a time range of automatic activation.

The widget allows you to change size and color of all texts, including the background transparency. Use the options to create an ideal digital clock for your device.

## Mathematical Formulas

The application contains well known and useful formulas of many different topics of mathematics. It is a great tool for (not only) students of grammar, high and university schools.

Please note that the app size is only 100 kB! The reason is that it contains NO IMAGES (except the launcher icon) and all formulas are rendered in run-time from text resources, using my own simple mathematical rendering engine. It also means that the application can be easily localized to any number of languages.

The formula text size can be increased or decreased and clicked to share in all ways your device supports (Facebook, email attachment, Google Drive etc.).

Enjoy! :-) And if you wish to add more formulas, please do not hesitate to contact me.

Explanation of permissions required by the application:

WRITE_EXTERNAL_STORAGE and READ_EXTERNAL_STORAGE: In order to share a formula on Facebook or attach it to an email, a PNG image file containing the selected formula must be created first and stored to the device. The files are very small and do not occupy any significant space.
