Zolia vs Steady

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.

Steady is a symptom and trigger diary for people living with one or more chronic conditions — the kind where symptoms move for no obvious reason, and the appointment is fifteen minutes long. Half a minute a day. Score how you felt, tick what happened. After a few weeks there is enough in the record to check whether anything you log lines up with how you feel — and when there is not enough, Steady says so plainly instead of inventing an answer. WHY THIS ONE IS DIFFERENT It is easy to build a tracker that announces your top trigger after a week. It is also easy for that answer to be water, because you drink it every day and there was nothing to compare against. Steady will not do that. Before it compares anything it needs at least ten days where a factor was present and ten days where it was not. It checks same day, next day and two days later separately, and corrects every comparison together, so that testing many things does not manufacture a result by luck. Until a pattern clears that bar, the Patterns screen shows you how close each one is and nothing more. WHAT YOU CAN RECORD • Any symptoms you choose, 0 to 10, named in your own words — pain, fatigue, brain fog, headache, nausea, dizziness • Factors — food, sleep, weather, stress, anything you want to test • Flares: a spike at noon that eased by evening, kept as its own event • Medications with reminders, including weekly, every-other-week and on/off cycle schedules • Period days, if you turn cycle tracking on • Sleep, resting heart rate, heart rate variability and steps from Apple Health, if you allow it (read only) • A note for whatever the numbers do not capture • Days you missed. You can fill them in later, and gaps stay gaps — nothing is smoothed over FOR THE APPOINTMENT The doctor's report is one page: how each symptom ran over the period, how closely you kept to your medication, and any association that held up — with the method stated, so a clinician can judge it rather than take it on trust. NO ACCOUNT, NO SERVER There is nothing to sign up for. Your record is on this iPhone and nowhere else — not on our servers, because there are none. Save a backup whenever you like; the file is yours to keep and yours to move. BOUGHT ONCE, NOT RENTED Everything you record is free and stays free: every score, the calendar, the charts at any range, reminders, backups and CSV export. Pro is a single one-time purchase — no subscription, and no trial to forget to cancel. It unlocks the full analysis and the doctor's report. The strongest pattern in your record is free as well. COMING FROM ANOTHER TRACKER Export a CSV and bring it with you. Steady shows you every symptom and factor it found in the file and asks what each one is before writing anything, and importing only adds — nothing already in Steady is overwritten. Two years of history is two years the analysis can start from. IN YOUR LANGUAGE English, Deutsch, Español, Français, Italiano, Português, 日本語, 한국어, 简体中文 and 繁體中文. Steady follows your iPhone's language, and you can pick another one just for Steady in iOS Settings. NOT MEDICAL ADVICE Steady describes what is in your own record. It does not diagnose, treat or prevent any condition, and it does not tell you what to do about what it finds. A pattern is a question worth asking your clinician, not an answer. Never start, stop or change a medication because of something the app shows you.
