Offline-first hotel booking system that syncs seamlessly during Zimbabwe's power outages.
Zimbabwean hoteliers cannot find affordable hospitality software that operates reliably offline during frequent internet outages.
ZimBook allows hoteliers to manage reservations, check-ins, and room occupancy entirely offline using local storage. When internet returns, all data syncs automatically to the cloud without conflicts. Affordable at $25/month, it's tailored for Zimbabwe's unreliable connectivity.
