iMessage Analyzer - Mac App
Analyzes a user's iMessages while providing cool functionality
Analyzes a user's iMessage database (chat.db*) to understand a user and their friends' messaging habits by graphing (and calculating statistics) on those characteristics.
Adds some unique functionality from Messages.app that provides a better experience, including a refined search for messages.
*chat.db, where a user's messages are stored, can be found in 2 ways:
- Where Messages.app (Apple's official Messages.app - iMessage for Mac) stores its data
- Where the iPhone's chat.db database is stored after a backup to the computer
Newest features
- Double messages: See who sends the most followup messages; defined as successive messages sent by the same person within 3 minutes to 8 hours of the last message send time
- Conversation starters: See who starts the most conversations; defined as who messages first after 8 hours of the last message in the conversation
Current Features:
- Looks like iMessage
- Contacts tableview on left side with contact name + profile picture
- iMessages you sent are in blue on the right side of messages panel
- Normal text messages you send are in green
- iMessages you received are in gray on the left side of messages panel
- Shows each message's date/time and read receipts
