About

Truly Simple Symptom Log

Read full description

Truly Simple Symptom Log is built around a single conviction: health tracking should take seconds, not minutes. Most symptom trackers are overbuilt and cluttered with complicated graphs, gamification, mandatory onboarding, and subscriptions that make the act of recording how you feel a chore. This app strips all of that away. It features a calm, minimal, one-screen logging interface that feels closer to a personal journal than a medical tool. It’s perfect for people with chronic conditions, people exploring cause-and-effect with their health, or anyone who just wants a friction-free way to log their mood and symptoms and then move on with their day. There's an in-app purchase that allows you to lock the app and export your data, but all core features are available in the free version and can be used for free as long as you like. Features: • One-screen logging: Record your mood, symptoms, potential causes, and notes on a single page. No tabs or multi-step wizards. • Heatmap calendar: A color-coded monthly data view gives you an instant visual summary of how you've been feeling over time, so patterns become obvious at a glance. • Accessible by design: Enlarged, comfortable touch targets prevent mis-taps when you're not feeling well. Fully optimized for VoiceOver screen readers and scalable dynamic text for low vision. • iCloud Sync: Logs sync silently and automatically across your Mac, iPhone, and iPad. Status indicators let you know your data is secure at a glance. • Free core features: All core logging is completely free. A single one-time, lifetime purchase unlocks optional data exports and a biometric privacy lock.
