Under the Hood
The Psychology of "Zero Latency"
Most apps are "Cloud-First", meaning they fetch data from a server every time you tap a button. This introduces a 200ms-1000ms delay.
Babelbits is Local-First. The entire database lives on your device (SQLite). When you tap "Save", it writes to the metal instantly. We use CRDTs (Conflict-Free Replicated Data Types)to sync securely in the background when you have Wi-Fi, but we never block your flow.
The SRS Engine
We don't use a standard linear timer. Our Spaced Repetition System (SRS) calculates the optimal review time based on "Ease Factor" and "Interval Modifiers".
Crucially, we track Production (Speaking) and Recognition (Listening) separately. Just because you can understand a word doesn't mean you can say it. Our algorithm knows the difference and will drill your weak side harder.
