When your labs come back "normal" but you know something is wrong, a daily record is your best evidence. Track 50+ symptoms across every body system and bring months of data to every appointment.
✓ Free forever · No credit card · Takes 60 seconds
Track the whole illness, not one diagnosis — 50+ symptoms across neurological, cardiac, digestive, musculoskeletal, and hormonal systems
Create custom symptoms for the ones standard apps ignore, and correlate flares with sleep, hydration, exercise, and cycle
Stop reliving your medical history out loud at every appointment — hand over the report instead
Chronic illness is messy. It does not stay in one body system, it does not show up on standard labs, and it rarely fits into a 15-minute appointment. My PeriScope was built by a woman with a genetic chronic illness who was tired of every doctor visit starting from zero.
Log everything — fatigue, brain fog, palpitations, histamine reactions, pain, sleep, digestion — rated daily on a 0–5 scale, with notes, voice memos, and a private journal. Over months, you get the thing every chronic illness patient deserves: a body of evidence.
Tap the symptoms you felt, rate their severity, add a mood and a quick note. Done.
Charts and AI insights built from your own data show you what is actually going on.
Export a PDF timeline of your symptoms. Hand it to your doctor. Stop being dismissed.
From finally understanding their patterns to walking into every appointment with real data.
"It's easy to use, keeps track of a lot of information that I would otherwise just overlook. Definitely useful for me as I navigate this next chapter of life."

"I found Periscope when I needed to keep track of my periods. It’s easy to use so it puts it all in one place. This helps me organize my thoughts and track whatever hormonal changes I’m going through 💐"
