Zolia: Efficient & Flexible Symptom Tracking Symptom trackers usually fall into two traps: they are either hyper-basic diaries that fail to capture real health complexities, or they require endless scrolling and menu-clicking, such that they aren't sustainable for consistent use. Zolia fixes this by giving you total control over the structure. It lets you organize your tracking however you want into custom sessions to eliminate wasted effort and repetitive tapping. You decide exactly what you want to track and how you want to track it. Core features: Customizable Sessions: Organize your tracking however you like. Create a morning session where you track your sleep and morning meds, a walk session where you track steps and how you felt, or anything else you can think of. Mix and match notes, symptoms, meds, ratings, factors, and more. Customize colors, emojis, and numeric ranges. Batch Log Medications: Use "Accept All Defaults" to log your standard medication protocol in a single tap, rather than tapping through every single item individually. You can also backfill specific date ranges if you need to catch up on past logs. Data Privacy & Free Exports: Your health data is stored entirely locally and never shared with external servers or LLMs. You can export your raw data via CSV or SQLite at any time for free, or set up optional automatic backups to your own private cloud storage. Data Analysis: The app looks for correlations across your history to help you find connections. Our Approach to Pricing: Basic logging, data entry, and data exporting on Zolia will always stay free. In the future, some analytics features will become part of a premium tier, but you will never be locked out of tracking or accessing your own daily data. Note: Zolia is a personal tracking tool and does not provide medical advice. Always consult your doctor regarding your health.

Tired of jumping between 3 apps to track one body? Zebra is a calm symptom tracker for people managing POTS, EDS, and Fibromyalgia. Track flares, symptoms, medications, salt, water, triggers, notes, and orthostatic vitals in one iPhone app, then turn your recent history into a doctor-ready PDF. Built for invisible illness, brain fog, and the appointment scramble. TRACK WHAT MATTERS Zebra helps you capture the pieces that are hardest to remember later: Daily flare severity and notes POTS, EDS, and Fibromyalgia symptom check-ins Salt and water tracking Medication entries Trigger notes Orthostatic vitals: lying, standing, and recovery heart rate and blood pressure Trends across your recent history GUIDED ORTHOSTATIC TESTS Use Zebra's step-by-step orthostatic flow to track heart rate and blood pressure while lying, standing, and during recovery. Enter readings manually or, when available, use HealthKit support for heart-rate capture. PROOF FOR YOUR DOCTOR When an appointment is coming up, Zebra can export a 30-day doctor report PDF with your flares, symptoms, medications, salt, water, triggers, notes, and orthostatic summaries. No more digging through Notes, screenshots, and memory the night before a visit. MADE FOR BAD DAYS Zebra is designed to be fast, gentle, and low-friction. Use curated symptom lists instead of building a tracker from scratch. Track what happened, leave optional details for later, and skip the guilt. Missing days do not erase your history. PRIVATE BY DESIGN Your health history is sensitive. Zebra is built as a native iPhone app using Apple's health and data frameworks. You stay in control of what you track and what you choose to share. FREE TO TRACK. PREMIUM FOR DEEPER HISTORY. Start with core tracking for flares, symptoms, medications, salt, water, triggers, notes, trends, and orthostatic vitals. Zebra Premium adds expanded history and doctor-report access for users who want more appointment support. Zebra is for people with POTS, EDS, and Fibromyalgia who want less app-juggling, clearer history, and proof they can bring to a doctor. Zebra does not diagnose, treat, or replace medical care. It helps you organize and share your own tracked history. Privacy Policy: https://zebratracker.app/privacy Terms of Use: https://zebratracker.app/terms
