"Clever PDA Software" The headline for many years on PocketIQ's website. "We are committed to providing you with top quality shareware and freeware software for your Psion or other Symbian/EPOC compatible computer." PocketIQ was an EPOC spin-off site from Palmscape I think and took over the sales/marketing of a reasonably large collection of mostly shareware applications.
The website was a bit intermittent for the first few months of this year (2006) and eventually went completely offline around mid-year. Hence I'll start to try to capture below all the applications and associated files that used to be available.

| BatCheck (50KB) | Peter Csutora |  BatCheck is a small and extremely useful application that monitors the status of the main and backup batteries. A must with rechargeable (NiCd or NiMH) batteries. These keep their voltage constant for a while, then even before your Psion gives you any warning they get exhausted. By configuring BatCheck to your own needs you will be warned in time to change batteries. Features: Unlike other programs that only tell you the status of the batteries when they are in foreground, BatCheck will gauge the battery levels at certain time intervals (1-60 minutes, selectable). Normally the program sits in the background using virtually no battery power itself, wakes up when its time for a checking, and goes back to sleep if the batteries are good, without disturbing you or being noticed. If the batteries are not good, the program comes to the foreground and warns you. You can select two warning levels for both the main and backup batteries: a 'low' and a 'replace' voltage level. By setting a warning level higher than the built-in levels you can prevent accidents caused by sudden battery power loss. If you want, you can ask the program not to warn you repeatedly, only once the first time when the main or backup levels reach the low level. Next time it will only warn you if the machine has been switched off then back on, or when they reach the replace level. You can ask the program to do a check at every switching on. If you have lots of other startup programs, you can select a delay time for battery check (0-20 seconds), so it will pop up after all the startup programs are done with their jobs. You can also ask the program to monitor if the external power is connected or not. This is great if you use your machine plugged-in, and the plug slips out of the machine without being noticed. You can select a top limit for the main batteries, to prevent accidental overcharge of rechargeable batteries by the mains adaptor. The program will tell you the voltage in 2 decimal values for greater accuracy (e.g. 2.28 Volts). Toolbar support and full system-compliance. Help file included. The program is compatible with the Psion Series 5/5mx, Revo/Revo Plus, Series 7/netBook classes of computers. The Help contains warning level suggestions for 5/5mx machines. In any case, it is recommended that you experiment with different warning levels and select the ones that best fit you, as battery types and machine usage varies.

Contact Manager is fast and allows contact information to be found quickly and with the minimum number of keypresses.Contact Manager is available in 2 versions: Contact Manager v5.1 for use on both the Psion 5 and the Psion 5mx. This version of Contact Manager utilises a standard Psion Data file in order to hold contact data. This means that contact data can easily be passed from one machine to another and read on any machine by using the standard Data application. Contact Manager (mx) v1 is for use only on the Psion 5mx. This version of Contact Manager utilises the data held in the built in Contacts application but provides a far better interface with links to other standard applications such as Agenda, Data and the internet software.

| Encrypt-It! (106KB) | Peter Csutora |  Encrypt-it! is a high security file encryption utility. Features: Featuring two very strong algorithms: a 256-bit RC-4-workalike and a 128-bit Safer SK. They are both used in many commercial applications like Netscape, Oracle, Lotus Notes, Apple security, etc. So far no one could crack them! Written in C++ and supplied as an OPX file, these algorithms work very fast: the top speed of RC-4WA is 90 kB/s, and Safer SK-128 is 52 kB/s (measured on a 1.5 MB file). This means that a typical file of 30 kB is processed in less than a second! Encrypt-it! is the only encryption program to use a one-way hash message digest function (Secure Hash Algorithm, programmed in C++) to make the final key used by the algorithm very secure. It scrambles simple passwords like "NikonF5" into almost true random characters. Furthermore, the program is able to generate unique keys even if you use the same password for several files. Securely wipes files before deletion to ensure that portions of files can't be recovered using disk editors. With all these features Encrypt-it! is the strongest and fastest encryption utility ever created for a Psion palmtop! The program itself is small, and very easy to use. Encrypts and decrypts any type of file. Batch mode: select up to 100 files from any folders, even entire folders, then encrypt/decrypt them using a single push of a button. You can even mix files to be encrypted and files to be decrypted in the list. Quick Decrypt function: if you want, you can decrypt a file quickly by launching it from the system screen. Quick Update function: the program launches files after decrypting them (Data, Agenda, Word, and most files created by third-party programs). After you edited the file it encrypts the file automatically. If the file was not changed, the un-encrypted version is wiped and deleted from the disk to make the process really safe. This is a great way to password protect even Agenda and Data files! Also features a stand-alone wiping tool: use it to "wipe" the free space on either the internal drive or a compact flash disk. This way, sensitive data even from deleted, un-encrypted files can't be recovered. Compresses Data files before encrypting to save disk space. Special integration with VReader5 to password protect text, e-text and tcr files. The program comes with an extended Help file. Installs in English, Italian, German, French, Dutch, Danish, or Hungarian. v4.0 Shareware - see Peter's home page at http://members.tripod.com/~csutora/index.htm for details. |

| FlashBack (49KB) | Peter Csutora |  FlashBack is a fully customisable compact flash-based backup utility for the Psion Series 5, 5mx and compatible machines. It is sophisticated yet easy to use. You just define personal profiles containing single files, folders or entire folder trees, and FlashBack takes care of the rest. It closes files that are open, backs up the profile, encrypts the files, then reopens the files it closed earlier. It reminds you whenever a backup is due. It checks the battery status to make sure that you never start a backup with low main batteries. You can also create shortcuts in your favourite folder: just one click on a shortcut, FlashBack starts, and performs the backup without one more keypress required. A detailed Help and Topic Help screens help you get started. Features: You can define three profiles with completely independent settings. Each profile can store up to 120 items. An item can be a single file, a file folder, or an entire folder tree. This way, if a file folder grows or changes, its new files and folders will automatically be included and updated. Built-in encryption. Uses encryption technology from the author's other shareware program, Encrypt-it! This will ensure the highest security and full compatibility with your other encrypted files. A reminder to alert you when a scheduled backup is due. Backup with one push of a button: you can create a desktop shortcut for a profile. Clicking on this shortcut will start the program, backup files for the selected profile automatically, and quit the program when the task is finished. A convenient way to backup directly from ExtraBars, HotKeys or Macro5! You can define whether you want to close open files and reopen them, simply close them, or just skip the process after backup. You can even configure the program to backup from one compact flash card to another! Just use one profile to backup from the card to the internal drive temporarily, change cards, and use another profile to backup these files to the other card. Built-in battery level check and other convenient functions. Full pen support, graphical printing, Topic Help screens, and detailed Help file. v1.2 Shareware - see Peter's home page at http://members.tripod.com/~csutora/index.htm for details. |

| dCalc - English (78KB) | Bob Hepple |  dCalc is a fully featured RPN (Reverse Polish Notation) calculator as popularised by Hewlett-Packard. Like the HP calculators it operates much more intuitively than calculators with an equals sign. dCalc was formerly shareware but Bob has issued a generic key making the program now freeware. v2.02 5/mx/MC218 - but works in 'letterbox' mode on larger screens.User: Free License Code: E75Y2ABF |
| dCalc - French (78KB) | Bob Hepple | French version of dCalc. Program modes: Financial mode - compound interest, present value, final value, interest, number of payments etc - these all work in the same way as in the HP calculators. Anuities can be set for the start or the end of the compounding period. Days between dates. Scientific mode - Sin, Cos, Tan, Sinh, Cosh, Tanh, log, ln, etc and their inverses. Statistics mode - Sum, Sum-, mean, std dev, factorial, Permutations & combinations, Linear regression. Programming mode - Bin, Oct, Dec, Hex, Ascii and Internet Address (IP) displays. AND OR NOT MOD and shift operations. Prime factors. Graphing of (X, Y) functions is built-in with control of axes and labelling and up to three functions on one plot. Plots can be exported to other applications. |
| dCalc - German (78KB) | Bob Hepple | German version of dCalc. Features: It features nice big clunky keys (easy to hit) and a nice big display. dCalc has a full set of stack manipulation keys (Roll, X<>Y, Enter, Sto, Rcl) which are so essential to the effective use of an HP calculator. It interoperates well with other Psion programs using the built-in copy and paste functions (^C and ^V shortcuts as normal). dCalc operates on real numbers with Scientific, Statistics and Financial functions or 32-bit integers (for programmers). The precision in Scientific, Financial and Statistics mode is the full precision of the Psion - about 15 significant places of decimals. As well as the stack, which is always visible (a nice plus over an actual HP calculator) there are 10 integer and 10 real registers to store numbers. All your numbers and settings are saved between sessions. Programmable keys - 5 keys (f1-f5) can be programmed by the user to execute the Psion's native OPL language which is similar to Basic. Thus you can create your own keys with your own labels e.g. "R100", a key to generate pseudo random numbers from 0-100 (OPL code is "100*RND") e.g. "%" a percent key by putting "y*x/100" into a function key The N-R key provides a Newton-Raphson iterative (numerical) solution for functions. All you need to do is put the function and its derivative (dy/dx)into the f4 and f5 programmable keys (marked f(x) and f?(x) and press the N-R button.
