WHY ASTER • Built for the transition years (ages 35 to 55), not just period tracking • Log 24 menopause-specific symptoms with severity in under 30 seconds • Syncs sleep, HRV, resting heart rate, steps, weight and cycle data from Apple Health, with no retyping • 100% on-device. Your health data never leaves your phone. TRACK WHAT MATTERS • Hot flashes, night sweats, insomnia, brain fog, anxiety, joint pain and more • Daily mood, energy and lifestyle tags (caffeine, alcohol, exercise, stress) • HRT, medication and waist measurements • A calendar history of every day PREMIUM INSIGHTS • Symptom Burden score with a clear severity band and monthly trend • Severity heatmap and time-of-day patterns • Personal patterns: how sleep, HRV and activity are associated with your symptoms • Cycle insights with a next-period window and transition cues • A before-and-after view comparing your symptoms around HRT changes • One-tap Doctor Report PDF for your next appointment PRIVATE BY DESIGN Everything is computed on your device.

You know your body changed. Now see if it's changing back. Log how you feel in seconds. When your dose changes, Dial shows the before and after - proof you can take to your doctor. THE DIAL One glance tells you where you are today, and whether things have eased since your last change. An honest instrument, not a mood ring. BEFORE & AFTER, FOR EVERY CHANGE Adjust your dose, add a medication, switch products - Dial marks it on your timeline and compares the weeks before and after. Each regimen gets a verdict you can stand behind. BUILT FOR REAL BODIES Track the symptoms that matter to you, your cycle as it changes, blood results, and the life events (illness, stress, surgery) that explain the wobbles your dose didn't cause. BRING THE RECEIPTS Export a clean PDF report - your trend, every change, and how each one landed - designed to be handed across a doctor's desk. PRIVATE BY DESIGN Everything stays on your phone. No account. No cloud. No tracking. Dial never gives medical or dosing advice. It shows you your own data, clearly - decisions stay between you and your clinician. 7 days free, then £3.99/month or £24.99/year.

Verdict
Aster and Dial are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
