iDailyDiary

I found this software "iDailyDiary" very useful. It ended my search for a software version of the diary. The basic version is a freeware with all the basic features enabled and with only certain add-on features like spell check, adding on tags that are missing. The only issue I think with this software is that the files created (one single file for one journal, not date-wise!) are stored with extension ".idd", and I do not think this extension is standardized. Any issue with the main software and all the journal entries might go for a toss.

Cool Cool

This is probably the best product in the Indian market. An ultimate cool one, especially in this heat.
