System requirements:

Programming calculator. You can write programs for stack machine (with simplified Java like instruction set). Program consists of one or more procedure which can be nested. It is possible to access variables of top procedure (like in Pascal). You can execute program ste-by-step and inspect stack and variables in debugger. Input of commands and thier operands is optimized for mobile phone. This calculator is using floating point arithmetic with quadra precision (64 bits for both mantissa and exponent) implemented by Nikolay Klimchuk.
Main features:
- PCalc keeps in database all your programs. A program consists of main procedure and may be some subprocedures. Program may have input parameters. The values of these parameters will be asked when program is started. Access to the parameters is performed using input instruction.
- PCalc provides stack-based language (like Forth). Operands are pushed on stack and operations are performed with top elements of the stack. Temporary results also can be stores in local variables (of self or outer procedure). Stack is also used to pass parameters to procedures and return values. Content of stack after return from main procedure is treated as program result. It is also possible view values of variables of main procedure (if program should return many results it is more convenient to store them in local variables).
- PCalc provides the following groups of instructions: load/store, operators, functions, control flow. Instructions of first three groups do not require extra explanation. Control flow instructions includes procedure call, return, conditional (IF) and unconditional (GOTO) branches. IF transforms control to the specified label if value on stack is zero. Label for these instruction is specified by selecting instruction in the list. Please notice, that when you are inserting new branch instruction it is not yet present in the list.
- PCalc provides wide editing capabilities. It is possible to add/remove/rename any variable/parameter/function. The only restriction is that it is not possible to remove entity which is used. It is also possible to move label (adjusting all branch instruction referencing this label) or change target of particular branch instruction.
- PCalc allows to introduce new variable only when you are specifying operand for STORE. Operand of load method is selected from the list of available variables. It somehow prevents programmer from using uninitialized variables.

Timer midlet allows to start simultaneously several times. Alarm time can be absolute and relative. It can happen once or with specified period. Different types of notifications are used: vibration, sound, backlight, SMS. Timers are stored in the storage so you can reuse them For example you can enter time needed for preparing some food (eggs, pizza, spaghetti...). Then you just select proper time and start it. Timer can be activated even if midlet is not active (at some models of the phones this feature may not work)
There four main screen in the program. The main screen is "monitor" - it shows state of active timers and allows to add new timer. The "List" command allows to see list of active timers and stop/change/remove any of this timers. "Settings" command allows to change midlet settings - way of alarm notification. When there are no active timers, monitor screen is empty. When you execute "Add" command, list of all timers in shown. You can select proper timer from the list and start it. If there are no timers, empty screen is shown. You can add new timer by executing "New" command. New timer can be saved or can be immediately started.
Timer form ask you to input hour, minute and second. For absolute timers it is time in the day when alarm should happen. For relative timer this values specify interval since current time. If timer is periodic, then relative time will produce alarm with the period equal to the specified interval. And periodic absolute timer will produce alarm each day at specified time (so period is 24 hours).
Timer midlet provides several way of alarm notification: sound (it is possible to configure frequency, volume and note of the signal), vibration, backlight and sending SMS. Also it is possible to specify duration of the alarm - period within which sound, vibration and other effects are produced. In case of alarm midlet shows model alarm alert which is visible until user execute "Dismiss" command. The command also stops sound, vibration and backlight. To be able to send SMS, it is necessary to specify destination phone number in settings. Unfortunately at most of the phones this mechanism will not work since phone will ask user permission for midlet to send SMS each time when it tries to send SMS.
System requirements:
- Java MIDP 2.0

Freeware Video Poker game.
System requirements:
- Java compatible.

This MIDlet will probe several aspects of your MIDP environment and list the results. In particular, it will try to establish a networking connection to check which protocols are available, check several limits of the built-in classes and do some benchmarking on the RMS and the overall device.

Counter for Java - ten counters on your mobile phone.
You can count everything you want (birds, flowers, your guests ect) and you phone will store all this information and can show it to you as a diagram.

Counter supports three modes:

Counting mode
Pressing 0-9 in this mode increase value of correspondent counter. Keys # and * can be used to switch between counters.
To see sum of values of all counters, choose Inspect command
To see diagram of counter values, choose Diagram command
To reset value of current counter, choose Reset command
To decrement value of counter, choose Undo command

Diagram mode
In this mode diagram of counter values is displayed. Pressing 0-9 in this mode increase value of correspondent counter.
To see sum of values of all counters, choose Inspect command
To reset value of all counters, choose Reset command.

Inspect mode
In this mode you can inspect values of particular counter. Pressing 0-9 in this mode choose counter to be inspected. Keys # and * can be used to sequentially switch between counters
To reset value of current counter or all counters, choose Reset command
To switch to counter incrementing mode, choose Counting command
To rename current counter, choose Rename command

This is an implementation of Swatch Internet Time.
