Show HN: RotaFlow – A privacy-first shift calendar built with SwiftUI

Hacker News - Thu, 02/26/2026 - 7:18pm

I built RotaFlow to solve the UX disaster of current shift work apps. Most incumbents are web-wrappers laden with ads.

The Stack:

* Language: Swift 6 / SwiftUI. * Persistence: Core Data synced via CloudKit (NSPersistentCloudKitContainer). * Architecture: MVVM with a custom "LoopEngine" for O(1) shift calculation.

The Interesting Part: I implemented a "Future Cliff" paywall. The app is fully functional for the next 30 days. Accessing dates beyond t+30d triggers a blurred UI layer. This aligns monetization with the value of long-term planning (vacations/weddings) rather than daily usage.

I'm a solo dev and handled everything from the icon design to the CloudKit schema.

Feedback on the onboarding flow (specifically the pattern builder dial) would be appreciated.

Show HN: I Built Smart Radio That Auto-Skips Talk and Ads by Using ML

Hacker News - Thu, 02/26/2026 - 7:09pm

Hi, I built TuneJourney to solve a specific annoyance: radio ads and DJ chatter. The core feature is an in-browser "AI Skip Talk" filter.

The Tech: Instead of processing on a server, it uses the Web Audio API to capture the stream locally and runs a lightweight ML classification model directly in your browser. It estimates the music vs. speech probability in near real-time. If enabled, it automatically triggers a "next" command to hop to another station the moment an ad, news segment, or DJ starts talking.

Features: - In-browser Inference: Entirely local and privacy-focused; no audio data ever leaves your machine. - WebGL + Point Clustering: Renders 70,000 stations across 11,000 locations smoothly. - Real-time Activity: See other users on the globe and what they are listening to in real-time. - System Integration: Full Media Key support for physical keyboard and system-level Next/Prev buttons. - Customization: Includes a talk sensitivity slider for the ML model so you can tweak the threshold.

Let me know what you think! I am interested if this project is worth further investment, building a mobile app, etc.
