GasSafe is a complete LPG safety and supply system built for Africa, especially West Africa where households use gas cylinders and leakages, fraud, and unsafe exchanges cause fires, shortages and loss of trust. It connects everyone in the gas chain — from the home to the depot to NPA( National Petroleum Authority) — on one platform, so every cylinder exchange is tracked, verified and safe. It consists of the following Apps/frontends all built during this hackathon using Muse-Spark - 1.3 xhigh and Muse-Spark-Open - 1026 1. Resident App The home safety app. It watches for gas leaks and when the cooker is left on for too long — when someone forgets, falls asleep while cooking, or steps out without turning it off. It sends instant alerts with a loud alarm to wake a sleeping person or get attention quickly. It also shows how much gas has been used, how much is left, predicts when it will finish, and reminds the resident to request a refill. 2. Rider App The delivery rider's work app. The rider receives refill orders from residents, scans the QR plate on the old cylinder at the house, confirms the house address with GhanaPost GPS, and logs the exchange of the old empty cylinder for a new full one. It records proof with weight, location and rider ID, so every delivery is accounted for. 3. Depot / Filling Station App For depot and filling station managers. It manages bulk stock — up to 200 or more cylinders at a time using the small bulk scanner — showing how many are full, empty, ready for dispatch, and how many have leaks. It syncs every exchange from riders and prepares batches for filling plants, so no cylinder is lost and stock levels are clear. 4. Filling Plant App For filling plant quality control. It checks every cylinder before filling — safety checks for valves, leaks and physical condition, and weight verification to confirm it is properly filled. It logs 400 or more cylinders at a time with the bulk scanner and passes only safe, correctly filled cylinders back to depots and riders, preventing underfilling and fraud. 5. GNFS Office App / Dashboard For GNFS officers in the office on computers. National officers see leaks and risks across the whole country, regional officers see their region, and district officers see their district. They can see which house has an active leak, where fire risk is high, and intervene quickly to prevent outbreaks. 6. GNFS Field Officer App / PWA The same GNFS dashboard on the phone for officers far on the field. When an officer is away from the office, they can still open their phone and see active leaks, fraud alerts and safety issues in their area, and respond without having to return to the office. 7. Estate Manager App / PWA For estate and property managers, on computer or phone. The manager sees all homes connected in the estate, which houses have active leaks and which house they belong to, and how each resident is using gas. It helps estates manage safety for many homes at once. 8. NPA Dashboard / PWA For NPA regulators at national, regional and district levels. National sees the whole country, regional sees their region, district sees their district. It shows every exchange — house, old and new cylinder serials, rider, verified address and MAPS location — plus fraud and safety alerts, depot and plant stock, and national analytics. It gives NPA full visibility of the cylinder exchange system under the Cylinder Recirculation Model.
