Centroid is a Location Based Reminder and Phone Profile Settings utility for Palm Centro GSM smartphones. Once you set-up the Centroid database, you can enable alerts and phone profiles when you are in a specific area. This is useful in case you need to remember something (e.g., buy groceries, etc.) when you are in a particular place. v3.5 onwards has support for messaging on entering or leaving a location. (e.g., message back home on reaching school or leaving office.)
                       

• Automatic collection of GIDs.
• Merge GIDs and specify your own Zones.
• Change phone settings when you arrive at a particular location. (e.g., forward calls to your home land-line when you arrive there).
• You can set the Theme, TimeZone (experimental), Mute Phone and System Sounds and Call-Forwarding.
• Alert at a particular location (e.g., set-up an alert to purchase groceries on the way back from work, when you are near your favourite store).
• Send messages automatically when you enter or leave a location.
• Timed phone settings profile cancellation.
• True one-handed operation.
• Tiny PRC (~ 78 KB).

• TimeZone settings are experimental as the current version.

• If a cell registration occurs while you are editing a location, then we have a problem - may result in "mixing" of records. I'll fix this, but it is all too boring.
