Changelog.

CURB is built in the open. Here are the changes that mattered — newest first. The complete commit-by-commit history lives on GitHub.

June 29, 2026

Data

Sweeper-pass times are now labeled as the city's real GPS, not an estimate — and coverage grew to 184 blocks (deduped, ≥3 real passes) as the city released more.

Open

Published the raw SF sweeper-GPS dataset in the repo (9,556 trips), with provenance and thanks to the city.

June 28, 2026

New

A small Pride-weekend touch on the map — a rainbow-outlined logo, date-gated so it retires itself after June. 🌈

June 26, 2026

New

Real "when the sweeper passes." Using San Francisco's actual street-sweeper GPS (public-records request #26-5451), blocks now show the truck's real pass time — and the data confirms a ticket lands a median of ~19 minutes after the sweeper. 🧹

June 25, 2026

Data

Rebuilt ticket timing from the complete citation record — about a million GPS-located tickets. The posted 2-hour window is really about 20 minutes.

iOS

The CURB iOS app went live on the App Store — free, a native wrapper of the same map.

New

Added open-source sponsorship links for anyone who wants to help keep CURB free and ad-free.

June 22, 2026

New

Configurable sweep alerts — choose the cadence (Light / Normal / Intense) and the voice (Cheeky / Drill / Deadpan), with a "send me a test."

New

A reporter-ready press kit at /press, and a self-activating "Get the iOS app" link.

June 19, 2026

New

Correct a Sign — spot a wrong block? Report it in two taps. Plus Share, Send-feedback, and Rate-CURB in the menu, and a Privacy page.

June 18, 2026

New

Surfaced the "park after the sweeper passes" rule, and a holiday heads-up when sweeping is suspended (e.g. Juneteenth).

Fix

Map stays reliable — it falls back gracefully to free tiles if the basemap hits its daily limit.

June 17, 2026

New

Richer neighborhood pages — per-neighborhood curb mix, off-street garages, and high-intent FAQs.

Data

Added "The receipts" to the About page — every data source and the methodology, in the open.

June 16, 2026

iOS

Native iOS push notifications and the iOS app groundwork, plus a launch trailer and App Store screenshot tooling.

Earlier in June 2026, CURB launched as a free, open-source map of San Francisco's street-parking rules — colored by the next street sweep, with real ticket timing per block. See it all on GitHub →
