NudgeSolo: Inspired by Learning Science

NudgeSolo isn’t just another reminder app — it’s built on solid research about how humans actually remember.
Based on the doctoral research of Dr. Kramer (2020) on professional learning and retention, NudgeSolo applies evidence from mastery learning, cognitive psychology, and spaced retrieval theory to help users retain what matters most — without effort or clutter.

Dr. Kramer’s study explored how post-learning reinforcement and feedback influence memory retention among adult professionals. Although traditional post-course email summaries showed limited effect on long-term recall, the research highlighted a key insight: timing, repetition, and meaningful context determine whether knowledge sticks.

That finding is at the heart of NudgeSolo’s design. The app replaces forgettable reminders with smart nudges that follow adaptive time intervals (like the Fibonacci sequence) proven to strengthen memory through spaced exposure. Instead of one-time notifications, NudgeSolo helps users build habits, not lists — using scientifically grounded intervals that align with the Ebbinghaus Forgetting Curve (Roediger, 1985) and Bloom’s Mastery Learning Model (Bloom, 1968).

Every NudgeSolo reminder is a miniature act of learning science in motion.
You choose a pattern, NudgeSolo handles the rest — rescheduling, pausing, and persisting seamlessly so your goals stay alive in memory.

“Spacing and feedback aren’t just for classrooms — they’re how humans form lasting habits. NudgeSolo brings that science into everyday life.”

Research Roots

Mastery Learning Theory (Bloom, 1968): Frequent formative feedback enhances mastery by reinforcing learning in progressive intervals.

Spaced Retrieval (Logan et al., 2012; Reynolds & Glaser, 1964): Distributed reminders improve long-term retention by revisiting learned material at calculated intervals.

Professional Learning Retention Study (Kramer, 2020): Demonstrated that post-event feedback alone is insufficient — timing and self-directed engagement are key to sustained recall.

Forgetting Curve (Roediger, 1985): Memory declines predictably unless information is revisited at increasing intervals.

Applied Cognitive Load Theory (Jamet & Fernandez, 2016): Clear, spaced cues reduce overload and strengthen recall through structured pacing.
