You Spent Hours Studying. Make Your Brain Keep It.
Your brain forgets 80% of what you learned within a week. Tag what matters during the day, and SomniCue replays those cues during deep sleep — directing your brain to consolidate the material that actually counts.
Download FreeWhy Studying Alone Isn't Enough
The Ebbinghaus forgetting curve is brutal: most newly-learned information is gone within a week unless you reinforce it. Spaced repetition (Anki, Quizlet) is the gold standard for active recall — but it works only on what you remember to review.
What about everything else? Your brain already replays the day during deep sleep. Without direction, it picks at random. SomniCue lets you decide what gets replayed.
What This Looks Like in Practice
During study sessions, your phone (or Apple Watch) plays subtle cues in the background — a sound or a haptic tap. You can also use Flicker Trigger™ to fire a cue manually at the exact moment you encounter a critical concept.
- Certification prep (CPA, CFA, USMLE, bar exam)
- Language vocabulary acquisition (any language)
- Medical terminology and anatomy
- Legal cases, history dates, scientific formulas
- Onboarding into a new technical role
- Conference learning, executive education
Stack It With What You Already Use
SomniCue isn't a replacement for active study — it's a multiplier on top of it. Use Anki, Quizlet, RemNote, or Notion for daytime review, then tag your hardest material in SomniCue for overnight reinforcement. The two systems work together: active recall during the day, targeted reactivation at night.
The Science Behind This Use Case
Rasch et al. — Sensory cues replayed during slow-wave sleep boosted memory recall by 97%.
Nature Neuroscience
Sound cues during slow-wave sleep enhanced declarative memory consolidation.
Nature Neuroscience
TMR significantly improved foreign language vocabulary acquisition.
Current Biology
Optimized cue timing during slow-wave sleep maximizes retention vs. random delivery.

Common Questions
Can I use SomniCue with Anki or Quizlet?+
Absolutely — they complement each other. Use Anki/Quizlet for active recall during the day, then add your hardest cards to SomniCue for overnight reinforcement.
How many things can I work on per night?+
We recommend 3–5 active items per night. Quality over quantity — focus on your weakest material rather than spreading attention thin.
Will I actually remember more?+
Most users report a noticeable difference within 1–2 weeks. TMR enhances consolidation but doesn't replace studying. You still have to do the work; SomniCue makes the work stick.
