TrackBack Symptom Tracker vs Caliper

TrackBack is the comprehensive tracking tool designed for people investigating chronic allergies, food sensitivities, IBS, migraines, eczema, and mysterious recurring symptoms. Whether you're just starting to track or looking to finally discover your triggers, TrackBack is here to support you every step of the way. VOICE-FIRST LOGGING Seamlessly log your symptoms and observations in 15 seconds. Speak naturally like "had rash after eggs this morning" and TrackBack automatically parses factors, symptoms, and timing. No forms to fill out, no endless tapping—just speak and go. PATTERN DISCOVERY Gain valuable insights into your health with detailed charts and visualizations. See correlations between what you eat, what you do, and how you feel. Understand your trends and identify triggers as you track. TARGET-FIRST INVESTIGATION Focus on what matters to YOU. Create custom investigations for specific symptoms you want to solve—that mystery rash, recurring headaches, digestive issues. TrackBack helps you investigate specific problems, not just journal everything. BIDIRECTIONAL TRACKING Track what makes symptoms worse AND what makes them better. Most trackers only let you log problems. TrackBack shows the complete picture so you can identify both triggers and helpful patterns. PRIVACY FIRST Your data is securely stored on your device using Apple's Private iCloud technology, keeping your information private and ensuring you stay in control. Export anytime, delete anytime. No tracking, no ads, no selling your health data. APPLE HEALTH INTEGRATION Automatically import relevant health data from Apple Health for a more comprehensive view of your patterns. PERFECT FOR TRACKING: - Chronic allergies and food sensitivities - Mystery rashes and skin conditions (eczema, hives, dermatitis) - IBS, bloating, and digestive issues - Migraines and chronic headaches - MCAS and histamine intolerance - FODMAP sensitivities - Any recurring symptom doctors can't explain HOW IT WORKS: 1. Define what you're investigating (your Target) 2. Voice log daily observations in 15 seconds 3. Review correlations in visual charts 4. Run elimination experiments based on patterns 5. Share detailed summaries with your healthcare provider BUILT BY SOMEONE WHO GETS IT TrackBack was created by someone dealing with chronic allergies and a four-month mystery rash that doctors couldn't diagnose. Built from frustration with symptom trackers that require 20 minutes of form-filling when you just need quick answers. FREE BETA TrackBack is currently free while in beta. We're building this WITH our users, not just FOR them. Your feedback shapes what we build next. Questions or feedback?

Most face apps guess from a photo. Caliper measures. Using the TrueDepth sensor — the same hardware that powers Face ID — Caliper captures 1,220 points of real 3D geometry and turns them into millimeter measurements: interpupillary distance, face width, jaw width, facial thirds, symmetry deviation and more. Every number comes with its ideal range, your percentile, and the published research behind it. MEASURED, NOT GUESSED - Real mm measurements from depth data, not pixel estimates - Repeatable to ±0.4 mm across scans - Every value cross-checked against published norms (300+ studies, 81 cited papers) - Tap any finding to read the actual research YOUR FACE MAP - Your own scanned 3D wireframe, not a stock head - Symmetry mirror mode shows exactly where left and right differ - Front, three-quarter and profile views with measurement callouts A 66-DAY PLAN THAT ADAPTS - Daily tasks built from YOUR weakest measured axes - Step-by-step guides: facial exercises, de-puff massage, posture work, skincare technique - Add concerns the scan can't see (acne, dark circles, thinning hair) — the plan retargets instantly - Honest expectations: every task says what it moves and when you'll see it SEE EVERY CHANGE - Milestone re-scans lock your progress in numbers - Change map shows where your face actually moved, in mm - Score trends, streaks, achievements and personal records MORE TOOLS - Color Analysis: your seasonal palette derived from measured skin values, not a quiz - Research Library: browse every cited paper with DOI links - Lock Screen widgets keep your streak and next task in sight - Export your scanned 3D face mesh (USDZ) AI, USED HONESTLY - AI coaching tips ride on top of the measurements — they never replace them - Future Self renders visualize where your plan is taking you, with bone structure locked: only habit-reachable changes are shown - Hairstyle Studio previews cuts on your own face, ranked by your measured face shape MEMBERSHIP Caliper is free to download.
