Hushknock reminds you to take your medication and keeps nudging until you confirm. It is discreet: the lock screen shows only the time, never the medication name, unless you choose otherwise. Everything stays on your phone. FREE, ALWAYS • Unlimited medications, any schedule: every day, every few days, specific weekdays • Nudges that repeat until you tap Taken. Choose Gentle, Persistent or Relentless, per medication if you like • Ring like a phone call: each nudge can ring for 30 seconds and gets through Focus • Discreet lock screen: "Time for your 9:00" instead of the medication name • Lock screen Live Activity and home screen widget for the next dose • Snooze, skip, and a streak that only breaks when a dose is actually missed • A dose stays open until your next dose of the same medication, so a late evening pill is not marked missed at midnight • Quiet hours and time zone handling for travel • Notes on any taken, skipped or missed dose, with quick reasons like "side effects" or "ran out" • Export your full history as CSV PRO • Insights per medication: on-time, late and missed, your weakest time of day, and one-tap fixes such as a harder nudge or a moved reminder time • 12-week history for every medication • Doctor report as a one-page PDF, with your notes if you choose to include them PRIVACY No account. No server. Your medications, doses and notes never leave your phone. Anonymous usage statistics only (which screens are used), no health data. IMPORTANT Hushknock is a reminder tool, not medical advice. Follow the instructions of your doctor or pharmacist, and never change a dose because of this app. Notifications depend on your phone's settings; the silent switch mutes the ring.

Verdict
The clearest difference is in-app purchases: Bionic Circle at none against Hushknock's 3. Hushknock's advantage is update cadence (every 2 days vs every 3 months). On price, ads, device support and iOS requirement there is nothing between them.
