Shalwa vs IPC Plumbing Code Calculator

Park, and forget about it. Shalwa pays for your street parking in Dubai so you don't have to. No app to open at the kerb, no zone code to text, no meter to find. Pull into a paid zone, walk away, and your session is already running. HOW IT WORKS Connect once. Shalwa links to your car through CarPlay, so it knows when you have arrived and when you have left. Setup takes about two minutes and you only do it once. Park anywhere in a supported zone. Shalwa detects the zone you are in and starts a paid session on your behalf, charged from your prepaid wallet. Drive off. Your session ends when you leave. You pay for the hours you were actually there. WHAT YOU GET Automatic sessions. Nothing to open, nothing to type, nothing to remember. Renewal handled. Shalwa keeps the session going before it expires, so a long lunch does not turn into a fine. A wallet, not a card charge every time. Top up once with Apple Pay, Google Pay or card. Your balance is refundable whenever you want it back. Every session itemised. See where you parked, how long for, and exactly what it cost, down to the minute. Live on your lock screen. Watch the session tick over without unlocking your phone, or ignore it entirely. GOOD TO KNOW Shalwa needs location and motion access, including in the background, to detect when you park and when you leave. Without it the app cannot start or end a session for you. Supported in participating paid parking zones in Dubai. More emirates on the way.
