The reminder names the drug, and you log the dose from the notification • Stopped a medication? It stays, with its history, ready to restart • Body signal: HRV, resting heart rate and steps from Apple Health against your own 30-day usual • Ask Ember: questions answered from your own logs, on your device, with no chatbot and no invented numbers WITH EMBER PRO • Flare Radar reads your own patterns and tells you at 8pm whether tomorrow is one to keep light • Pacing warnings during the day, while a crash can still be avoided • Every pattern, the cycle overlay and your complete history, not just the last 30 days • Appointment mode drafts your questions, shows your numbers in large type, and records what changed • Share your last 30 days as a one-page PDF made on your device, no AI and no internet • One AI Visit Brief a month that turns your logs into a page your clinician can read in under a minute • Experiments: drop one factor for two weeks and compare, sample size included ALSO • Apple Watch app for two-tap logging, plus Home and Lock Screen widgets • Goals where a day too unwell to log does not break the streak • Your own measurements beside your pain: water, weight, blood pressure PRIVATE BY DESIGN • Your logs live on your device and in your private iCloud • Your logs reach our server only when you generate an AI brief. They are processed in memory, never stored, never sold • Ember also sends anonymous usage events, such as which screens you reach, to work out what to improve. Never what you logged, and you can switch it off in Settings • Erase everything you have logged from Settings at any time Ember Pro is an auto-renewing subscription, billed monthly with a 7-day free trial, or yearly.

Verdict
The clearest difference is in-app purchases: ErgoTrend at none against Ember's 2. ErgoTrend also leads on iOS requirement (9.0 vs 17.0). Ember's advantage is update cadence (every 2 weeks vs every 29 months). On price, ads and device support there is nothing between them.
