Welding Gas Cylinder Tracker is an independent, local-first cylinder recordkeeping tool for welders. It helps you keep track of cylinders, suppliers, ownership or rental relationships, status, costs, exchanges, refills and reminders.
The current release is cylinder-only. It does not scan cylinders, use the camera, track consumable lots or certificates, read pressure or location sensors, or make welding-safety, transport, workplace, ownership or compliance decisions.
The iOS free plan supports up to two active cylinders. A one-time non-consumable Pro purchase permanently unlocks unlimited active cylinders. The United States reference price is US$2.99. App Store Connect controls geographic storefront prices, and the price, currency, taxes and transaction details shown by Apple before confirmation are authoritative. Choosing Upgrade opens Apple’s purchase sheet directly; the app has no separate in-app price screen. The app does not calculate a price from device location or hard-code the U.S. price into customer-facing purchase screens. The permanent unlock does not renew automatically.
No GoodUse Studios account or cylinder-record server is required. Core records remain on the device unless you choose to export a backup. The final production model contains no advertising SDK, advertising-consent service, analytics SDK, attribution SDK, tracking SDK or third-party crash-reporting SDK. The app uses local notifications only when you enable reminders.
GoodUse Studios intends to make the iOS app available in every App Store country or region that Apple permits it to enable except China mainland. China mainland is excluded unless and until the required local filing is completed and accepted. Actual availability remains subject to App Store support, local requirements and Apple’s decisions.
