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. ◆ 3 Core Features of ThoughtTrace ◆ 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). ◆ Privacy First ◆ 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.

Screenshots you forgot you took. Links you shared and never reopened. Tuck remembers them for you. Coupon deadlines, bookings, deliveries, read-later links — just take a screenshot or share it to Tuck. It reads the content and reminds you right before it matters. How it works 1. Take a screenshot, or pick Tuck in any app's share sheet. 2. Tuck analyzes it on your device and finds the deadline and the next action. 3. A reminder arrives before it's too late — one tap runs the action. What Tuck detects • Coupon and voucher expiration dates • Bookings, shows, and flights • Delivery updates and tracking numbers • Payments and bills • Places and addresses • Links to read later One-tap actions Use the coupon, add to calendar, track the package, open the map, reopen the link — right from the card. Done items move to the Archive and stay reachable. Private by design • All analysis happens on your iPhone. Nothing is sent to a server. • No account, no sign-up, no cloud. • Your photos stay untouched — deletion always goes through the iOS confirmation dialog. Every core feature is free. Just take the screenshot. Tuck reminds you at the right moment.
