ThoughtTrace
Read full descriptionHide full description
"Think analog, save digital." ThoughtTrace is a seamless tool to digitally save and organize the deep thoughts you've written down with pen and paper. Some ideas are only born when you freely move a pen across a blank sheet of paper, rather than typing on a keyboard. ThoughtTrace maximizes this "handwritten thought process" and securely manages your notes afterward. β 3 Core Features of ThoughtTrace β 1. "Intelligent Timer" for Deep Thinking Place your iPhone or iPad on the corner of your desk and set the focus timer. Setting a time limit flips the switch in your brain to "just write." 2. "High-Quality Continuous Scan" for Handwritten Notes Once you finish writing, simply point the app's camera. It automatically detects document edges, removes hand shadows and wrinkles, and instantly converts your notes into crisp, highly legible black-and-white data. You can also continuously scan multiple pages without closing the camera. 3. Reflect and Organize (Folders, Tags, PDF Export) Beautifully organize your scanned notes using folders and tags. Look back on the trajectory of your thoughts through a chronological timeline. You can also combine multiple notes and export them as a single PDF (*Pro feature). β Privacy First β All your ideas and notes are saved strictly on your device. They are never sent to external servers, allowing you to write down your thoughts with complete peace of mind. *The free version has a daily limit on the number of scans. Upgrade to the Pro version with a one-time purchase to unlock "Unlimited Saves," "No Ads," and the "PDF Export" feature.
