Mobile AI reply metrics
The most important mobile AI reply metrics are copied selected drafts, repeat mobile sessions, return-to-app behavior, Android copy-back friction, iPhone context-handoff friction, browser-first social sessions, and manual approval comprehension. These metrics support TypeToSell's rollout order: mobile web + share/copy first, Android ReplyPilot Keyboard second, iOS keyboard plus Share Extension third, then Safari iOS and Firefox Android extensions for browser-first users.
Last updated: July 11, 2026. These are rollout metrics, not customer outcome claims.
Measurement purpose
What this metric set should prove
Use these metrics to decide whether a mobile surface is proving demand or only adding implementation complexity. The goal is to measure explicit context, selected draft action, copied or inserted handoff, repeat usage, and user-controlled final posting.
Core metrics
Which events should be measured?
Repeat mobile sessions
Separates first-time curiosity from an actual phone-based reply habit that can justify roadmap priority.
Suggested event: mobile_reply_session_returned
Return-to-app completion
Indicates whether share/copy workflow friction is tolerable before native surfaces exist.
Suggested event: mobile_return_to_social_app_confirmed
Native friction tags
Shows whether the next bottleneck is Android insertion, iOS context handoff, or browser-session coverage.
Suggested event: mobile_reply_friction_tagged
Leading indicators
What should move before roadmap priority changes?
Mobile web should move first
A rise in copied selected drafts and repeat sessions is the strongest signal that the share/copy MVP is worth improving.
Android should follow copy-back friction
Android ReplyPilot Keyboard earns priority when Android users already copy drafts but complain about switching apps or insertion speed.
iOS should follow context friction
iOS keyboard plus Share Extension earns priority when iPhone users need both source context handoff and selected draft placement.
Browser extensions should follow browser sessions
Safari iOS and Firefox Android extensions matter when users actually reply from mobile browser social pages.
Decision rules
How should these metrics guide the roadmap?
Do not build native from one generation
A single generated draft is not enough evidence; copied selected drafts and repeat sessions matter more.
Fix draft quality before insertion
If users generate but do not copy, native keyboards will not solve the core product problem.
Treat browser extension as fallback
Browser-extension metrics should not be used as proof that native X app composer friction is solved.
Fail on unclear approval
If users think TypeToSell posts for them, the safety metric should block copy, page, or product launch.
Instrumentation guardrails
Keep metrics honest
Keep metrics as product signals
Label metrics as TypeToSell rollout and safety signals, not customer outcome claims, revenue lift, reply-rate guarantees, ranking proof, ratings, or reviews.
Separate generated from selected
Track generation starts separately from selected copy or insertion so the team does not confuse curiosity with real workflow completion.
Keep final posting outside TypeToSell
Measure draft handoff and copied or inserted text, but do not instrument TypeToSell as the system that presses the final public platform button.

FAQ
Metrics questions
What is the best first mobile AI reply metric?
Copied selected draft rate is the best first metric because it proves the user found one draft worth moving into the social app.
What metric unlocks Android ReplyPilot Keyboard?
Repeated Android mobile web usage plus copy-back or insertion complaints is the strongest keyboard signal.
Are these metrics customer outcome claims?
No. They are rollout and workflow metrics, not revenue, reply-rate, follower, review, or ranking claims.
