See your scratch-and-flare cycle clearly
Cosi Care pairs photo logs with a symptom diary to catch what triggers your skin's bad weeks, then guides the right care step.
Free to start. No card needed to sign up.
Track once. Understand your skin.
Three quick steps build the picture your skin has been trying to tell you for years.
Photograph the skin
Take a photo of the affected area. Cosi Care timestamps and maps it to a body region automatically.
Log symptoms and context
Answer a short daily check-in: itch intensity, sleep, food, stress, and any new products.
Receive pattern insights
The AI surfaces correlations between triggers and flares, and prompts care steps at the right moment.
Everything your skin journal should be
Designed around the real patterns of eczema, psoriasis, and other itch-prone conditions.
Timeline view
See your full photo and symptom history as a chronological timeline. Spot when flares started and what appeared in the days just before.
Trigger correlation
The AI matches your logged context (diet, stress, products) against flare timing to surface your personal trigger patterns.
Care step prompts
When the pattern predicts a rough patch ahead, Cosi Care surfaces the care actions most likely to reduce its severity.
Clinic-ready report
Export a structured summary of your flare history and triggers for your dermatologist appointment in two taps.
Family mode
Manage tracking for children or multiple family members from one account, each with their own separate logs and care plans.
Evidence-based guidance
Care suggestions are grounded in established dermatology guidance. Cosi Care helps, it does not diagnose.
Your skin tells a story. Most journals miss the first chapter.
Most flares have a build-up phase two to four days before the visible reaction. Cosi Care's daily photo log captures that window, giving the AI enough context to spot the early warning signals you've likely been overlooking.
See the full methodCare prompts arrive before the flare peaks, not after.
When Cosi Care recognises a familiar build-up pattern, it suggests which care steps have helped before and flags known triggers to avoid. You spend less time reacting and more time preventing.
Start tracking freePatterns most people never see coming
Designed around the real picture of how eczema and psoriasis actually behave week to week.
Sleep disruption and flare severity often track together with a two-day lag. The photo timeline makes that connection visible in a way a written diary rarely does.
Stress-triggered flares tend to appear three to five days after a high-stress period, not immediately. Logging daily makes that delay visible over time.
When you arrive at a dermatology appointment with a structured trigger log and dated photos, your doctor can make decisions from evidence rather than memory.
Built around the conditions that need this most
Atopic eczema
Eczema flares are intensely trigger-dependent. Cosi Care tracks dietary, environmental, and stress inputs against photo evidence to find the specific drivers for your skin.

Psoriasis cycles are longer and harder to read day-to-day. The multi-week timeline view reveals the slow-build pattern that short diary entries miss entirely.
