Cairn is a text export tool that turns a text conversation into a clean, printable record you can keep or hand to someone who needs it. It works from screenshots of the chat that you add, then rebuilds the conversation in order so you can export text messages to PDF & CSV in a few taps. - Add screenshots of a conversation and let the app read the bubbles and sort them by time - See the conversation rebuilt in order, with sender labels and any gaps flagged, never silently reordered - Save messages to PDF & CSV: a crisp PDF with selectable text you can print text messages from, or a CSV with date, time, sender, and message - Reactions and inline images are carried into the export - Everything happens on your device, and your screenshots never leave your phone iOS does not let apps read your SMS or Messages history directly, so Cairn works from the screenshots you provide, turning them into a fast, accurate backup or recovery record you can print or file away.

Verdict
The clearest difference is in-app purchases: DWTools at none against Cairn's 1. DWTools also leads on iOS requirement (15.0 vs 26.0). On price, ads and device support there is nothing between them.
