You know your pain is real. Aster helps you prove it. People with endometriosis wait years for a diagnosis — and those who feel dismissed by their doctors wait longest. What finally gets someone believed usually isn't a number. It's being able to say what the pain feels like, and what it stopped them doing. Aster records all three. HOW BAD, WHAT KIND, WHAT IT COST A 0–10 scale for intensity. Pain character — cramping, labour-like, burning, squeezing, stabbing, dragging, nerve-like. And how much the episode disrupted your day, from barely to couldn't get out of bed. LOG A FLARE IN SECONDS Built for your worst days: big tappable targets, one-tap symptom and location chips, no typing required. Log from the app, your Lock Screen, or a Home Screen widget. Choose which symptoms appear on your log screen so it stays fast. TRACK WHAT ACTUALLY HAPPENS TO YOU Twenty-three symptoms across thirteen pain locations. Cramps, bloating and endo belly, fatigue, brain fog, nausea, clotting, heavy bleeding, spotting, constipation and diarrhoea tracked separately, bladder urgency and leaking, pain with sex, headache, lightheadedness, mood changes and more — across pelvic, abdominal, lower back, hip, thigh, leg and bowel locations. A REPORT DOCTORS TAKE SERIOUSLY Generate a clean one-page PDF designed around what a clinician needs: average and peak pain, flare days per month, your most frequent symptoms, how pain lines up with your cycle, what it's costing you day to day, and the treatments you've tried. Timestamped, structured, and hard to wave away. SEE YOUR PATTERNS Charts show pain over time, symptom frequency, and how symptoms line up with your cycle — so you spot the patterns before your specialist asks. COMPLETELY PRIVATE No account. No cloud. No tracking. Everything stays on your device, protected by Face ID if you choose. We can't see your data — we built it that way on purpose. FREE VS PREMIUM Logging, cycle tracking, reminders, basic trends and the basic doctor report are free — forever. Premium ($3.99/month or $29.99/year, 1-month free trial) adds cycle-day and phase analysis, custom report ranges, medication effectiveness insights, appointment reminders and unlimited history export. Aster is a symptom record, not medical advice, and it doesn't diagnose anything — only a clinician can do that. Your pain deserves to be on the record, and taken seriously.

Verdict
The clearest difference is in-app purchases: Splendid Insight at none against Aster's 2. Splendid Insight also leads on update cadence (every 3 days vs every 3 weeks) and device support (3 vs 1). On price and ads there is nothing between them.
