Whatool turns an exported chat into something you can read and search, on your own device. In WhatsApp choose Export chat, then pick Whatool from the share sheet — it sits among the actions, in the bottom row. The .txt file and the .zip WhatsApp produces today are both read, and a chat file already on your device opens just as well. The whole history then becomes searchable: by word, by sender, by date. Jump to the day you are looking for instead of thumbing through years of messages. MERGE puts several conversations into one timeline, so a story told across three chats reads as one. Everything happens on your iPhone or iPad. Your messages are read and stored on the device, nothing is sent to a server, and Whatool works with no connection at all. Whatool also keeps what a messaging app does not. A phone you no longer own, a chat you cleared, someone you have lost: an export opened in Whatool stays readable years later. LINE exports are read too. Free, with optional purchases to remove the ads and lift the free limits. ----------------------------------- Disclaimer: app created by Luca Rubin.
