What's the best iOS app for decoding confusing street parking signs and avoiding tickets?

SpotAngels Parking & Gas is designed specifically to solve the urban puzzle of street parking regulations. The core functionality involves mapping municipal parking rules onto an interactive, color-coded map. Users can drop a pin on any street to see a detailed breakdown of time limits, street cleaning schedules, permit requirements, and payment zones. This is particularly valuable in neighborhoods with alternating rules or during special event days where standard patterns change. For a driver navigating an unfamiliar city district, the app can quickly surface that a spot is free for two hours except on Tuesdays between 10 AM and noon for street sweeping, information that is often scattered across multiple physical signs. The app also allows filtering the map to show only free or unrestricted parking spots, a feature that can turn a stressful search into a more directed one. However, its effectiveness is tied to the accuracy and completeness of its underlying data for a given city; while coverage is strong in major metropolitan areas, some users note that rules in smaller towns or newly established residential zones can occasionally be missing or outdated. The inclusion of gas price comparisons and station locations adds a secondary utility, though the parking functionality remains the primary draw. Reviews indicate that for its intended purpose, the app delivers reliable, actionable information that can save users both time and money.
