ZoneView vs Aligner Tracker

ZoneView turns your Apple Watch into a heart-rate-zone training companion. One glance gives you what matters mid-workout: your current zone (as color), your heart rate, and elapsed time — on the Watch, mirrored live on your iPhone, and on the Lock Screen and Dynamic Island. TRAIN BY ZONE • Live zone color, heart rate, elapsed time, and time-in-zone bar • Gentle wrist taps when you cross a zone boundary • Zones estimated from your age, or set fully custom boundaries OUTDOORS • GPS route recording for outdoor walks and runs • Zone-colored route map, distance, pace, and per-split breakdowns AFTER THE WORKOUT • History and trends: weekly zone minutes, training load, streaks, and personal records • Home Screen and Lock Screen widgets for weekly progress • Export your history as CSV, or share a workout summary card PRIVATE BY DESIGN • No accounts, no ads, no analytics — ZoneView makes no network connections • Your data lives in Apple Health and on your devices, nowhere else Requires a paired Apple Watch (watchOS 10+). ZoneView is not a medical device.

AlignerDiary is your personal clear aligner journal, bringing daily wear, tray changes, orthodontic appointments and photos together. Redesigned navigation across five tabs makes recording and looking back feel more connected. No registration required. Log when your aligners are in or out Tap when you take them out or put them back in to view your recorded wear time. Add or correct missed entries, record how you feel and leave a note. Review each set of aligners Browse a calendar and daily timeline for each set, with wearing, removed and unknown periods shown separately. Enter the change dates and orthodontic appointments set by your dental professional, and add local reminders. Keep your everyday photos together Take photos or import several at once, organized by date and aligner set. Use the camera guide and 3-second countdown, then adjust the image after capture. Dates appear on thumbnails. Swipe left or right through photo details, or browse with the thumbnail strip. Compare multiple photos in stacked or tiled layouts: pinch to zoom them together, then pan them together while zoomed in. Photos are for personal review; the app does not assess treatment results. Look back with wear-time charts Choose a window of up to 7, 30 or 90 days, limited by your actual history. View daily recorded wear time alongside your goal curve. Recent summaries and per-set averages stop at yesterday; today is marked as in progress. Unknown time is not counted as zero. Make it feel like yours Choose from four color themes, with light and dark modes. The app supports ten interface languages, including Simplified and Traditional Chinese, English, Japanese and Arabic. Your records and photos stay on your device by default. Export a complete manual backup including photo files, or use a private iCloud backup in your own Apple account. iCloud backup requires an available account and network access. Backup is not two-way sync between devices. Optional, voluntary one-time tips are not subscriptions and do not unlock features. AlignerDiary is for personal records. It does not provide diagnosis or treatment advice, assess treatment outcomes or automatically change your treatment schedule. Follow the plan set by your dental professional.
