For Lumen's onboarding, should the first screen ask for a goal or just start with one habit?
Start with one habit. A single concrete action gets people to their first "done" fastest — you can layer goals in once they've felt a streak. Want me to sketch the first three screens?
Yes, sketch them.

Tighten the catch-up card copy a little?
"Missed a day? Your streak's safe — tap to catch up." Shorter, still warm, and never shames the miss.
Perfect.
Before native quietly drops old messages to fit its context window, ChatExtender opens a fresh session with a full summary + your saved memory attached — so nothing important is silently lost.

Starting a new session for faster responses. Your full conversation history is preserved locally.
Context that never silently degrades. Long native chats quietly compact and forget as they grow. ChatExtender hands each new session a complete summary of everything before it — automatically, before anything is lost.

Draft the App Store subtitle for Lumen.
"Build habits that survive real life." It leads with the forgiving streak system and keeps the warm, no-shame voice. Want two alternates on the same line?
Yes, keep them on-voice.
Attached to this message: your saved brand voice + feature list. The model gets your project's facts before it answers — so it stays on-voice without being re-briefed.

App-level search — not the model. ChatExtender instantly searches every thread in the current provider and highlights the matches, even one buried thousands of messages back.
Walk me through the grace-day reset once more so I can write it up.
A streak survives one missed day per week, and only resets on the second miss in the same week. Store streak_count plus a per-week miss counter, and reset when that counter hits two.
Got it.
