Alex was experiencing frequent fainting, and her family noticed the episodes often followed a rapid rise in her heart rate. She wanted a heads-up the moment that started happening. Alex uses TachyMon's alerts as a cue to sit or crouch down when her heart rate climbs quickly, and she finds the app helps her feel a bit more in control of her day. It is a simple but specialized app, and we hope it may help others with POTS, or anyone who wants to be alerted to changes in their heart rate.

Sodi — Sodium Tracker & ScannerTake command of your heart health with Sodi, the definitive tool for tracking sodium, monitoring blood pressure, and revealing the hidden salts lurking in your daily diet. Whether you are managing hypertension, following a heart-healthy diet, or simply curious about what’s in your food, Sodi transforms complex nutrition labels into clear, actionable health insights in seconds. Why Track Sodium?Excessive salt intake is a leading contributor to high blood pressure and heart-related concerns. Yet, standard nutrition labels can be deceptive. Sodi removes the guesswork by providing a "Smart Label Scanner" that instantly calculates sodium content, your percentage of daily goals, and true servings per container. Key Features for a Healthier You. Smart Label Scanner & ParserInstant Analysis: Point your camera at any food label for a live analysis of sodium levels. The Serving Fix: Avoid the "Hidden Serving" trap. Sodi’s parser extracts "servings per container," allowing you to toggle between per-serving and whole-container math so your logs are always accurate. 1. Visual Framing: Use the glowing framing overlay and torch support to scan labels even in low-light grocery aisles. 2. The Animated Sodium RingAt-a-Glance Tracking: Your "Today" screen features a dynamic ring that fills as you log, visually representing your daily budget. Real-Time Stats: Instantly see your total items logged, percentage of goal reached, and exactly how many milligrams you have remaining. Over-Limit Alerts: Receive a heavy haptic thump and a coral "Over Limit" warning the moment you cross your daily threshold. 3. Frictionless Logging & ShortcutsQuick Add Favorites: Access a strip of your frequent favorites—like a morning bagel or coffee—and log them with a single tap. Siri Voice Integration: Hands full in the kitchen? Simply say, "Log sodium in SodiumScan." Siri will ask for the food and amount, queuing the entry for your next app open. Auto-Promote: The items you scan most often are automatically promoted to your favorites for faster access. 4. Deep Ingredient Intelligence 25+ Flagged Ingredients: Sodi doesn't just look at numbers. Our knowledge base flags ingredients like MSG, sodium nitrites, carrageenan, and phosphates. Plain-Language Reasons: Every flagged ingredient comes with a BP-focused explanation, helping you understand why it affects your health. Healthy Alternatives: Receive smart suggestions for lower-sodium alternatives tailored to the product type, from soups and chips to deli meats and sauces. 5. Contextual Education & Hidden Alerts The "Stealth" Salt Alert: Sodi identifies foods that are deceptively high in salt, such as cottage cheese, bread, and dressings. Did You Know?: Tap any alert to see the typical sodium range for that category and learn how to make better choices. 6. The Dilution CounterHydration Balance: Sodium and water go hand-in-hand. Sodi features a water progress bar that scales based on your salt intake—increasing your hydration target on high-sodium days to help your body recover. Advanced Health Integration with Apple Health (HealthKit): Sodi requests authorization to read and write dietary sodium, water intake, and blood pressure (systolic/diastolic). Doctor-Ready Reports: View 7-day bar charts that correlate your salt intake with your BP readings, making your next medical check-up more productive. Custom Targets: Choose from presets (1,500mg / 2,000mg / 2,300mg) or set a custom slider based on your physician’s recommendation. Privacy & Security On-Device Processing: Most analysis, including label scanning and serving math, happens directly on your iPhone to ensure speed and total privacy. Your Data is Yours: We never sell your health data to third parties. Your information is governed by Apple’s strict HealthKit privacy standards.
