This utility is super. It keeps track of several items that are important to your handheld.
Keep up-to-date on things like battery usage, free memory, days since last reset and more. This application has the ability to keep your handheld in tip-top shape if you keep up on all of the maintenance. You can perform record-level or resource-level database editing. It even includes an auto-sleep timer and a serial port debugger.
