"Live today" means running in production on the founder's own four App Store apps (LuminaClean, BookBinge, TicFlow, and Inkfall) right now, not in a demo. If a feature is anywhere short of that, it's listed lower down. No feature appears here before it exists.
Live today
In production on the founder's own portfolio.
- Self-serve signup at app.foliokit.io — create a free account and add an app; Free covers one app, no invite needed
- Swift SDK (0.5.x) — events, screens, sessions, offline queue and batching
- One-ID identity: SDK-generated user ID shared with RevenueCat — including ID adoption for apps with existing subscribers
- Dashboard: live event feed, DAU, session length, top screens
- Retention & lifecycle cohorts — event-anchored, so ghost users don't inflate the numbers
- Breakdowns by app version, OS, country, device
- Revenue joined to users via the RevenueCat webhook — paying-user flag reconciled daily against RevenueCat entitlements
- AI weekly brief, generated every Monday — see a full sample
- Anomaly detection — daily z-scores against each app's trailing 28 days, folded into the brief
- Chart annotations — mark releases and campaigns on the DAU chart
- Remote config, feature flags, minimum-version signal, server-gated rating prompt
- Apple Search Ads attribution via AdServices — deterministic, no ATT
- SKAdNetwork conversion values — mapped from server config, retunable without an app update
- App Store Connect ingestion: daily downloads, monthly actual net proceeds
- Internal-traffic filtering — your own devices and simulators excluded from every chart
- Hosted, versioned integration docs — the copy-paste prompt references the guide, so improvements reach everyone
Running, still hardening
In daily use, but young enough that edges are still being sanded.
- Landing-page tracking snippet — page views, store clicks, campaign attribution, time on page
- P&L per app — Apple's actual proceeds minus your real costs, with a manual payout override
- Funnel view — onboarding, paywall, trial, purchase, distinct users per step
- iOS companion app — portfolio overview, live feed, and revenue on your phone
Coming
Built or planned, not yet in production. No dates promised.
- Push alerts — purchase "ka-ching" and the Monday brief on your phone; built, in final wiring
- Apple Search Ads spend flowing into the P&L automatically
- MRR and active-subscription state tracking
- Server-side conversion forwarding to Meta / TikTok / Reddit — outcomes, never identities
- Campaign-level SKAN postback endpoint — see your own postbacks, not just the ad network's
- Paid plans — billing isn't live yet; founder pricing is reserved in signup order for the first 100 paid accounts
- Public data export UI — until then, export is on request and always available
Won't build
Absences by principle, not by backlog.
- Session replay, screen recording, heatmaps
- Autocapture of every UI interaction
- Fingerprinting, IDFA use, cross-app device graphs
- User-level paid-social attribution — per-user link-to-install-to-purchase needs the tracking Apple prohibits; the exact explainer
- Replacing RevenueCat — FolioKit requires it and completes it
