Work the right doors with a field companion built for KnockGenius representatives. Start each shift with your assigned territory, ranked knock list, and the door intelligence you need before you walk up. Review the likely conversation angle, open maps, and log the result in a few deliberate taps. KnockGenius keeps field work moving when connectivity is weak. Assigned territory data is stored in an encrypted offline cache, and queued outcomes sync automatically when your connection returns. Use KnockGenius to: • Review assigned territories and route progress • Work a prioritized, route-ordered knock list • Open per-door intelligence and compliant conversation guidance • Sort nearby assigned doors when you choose to share foreground location • Log outcomes, objections, confidence, notes, and consented follow-ups • Review pending, failed, and confirmed outcomes • Receive territory and follow-up notifications Location is optional and used only on device when you choose Nearest. KnockGenius does not sell mobile user data or use it for third-party advertising. An existing KnockGenius account with an assigned territory is required.

Verdict
The clearest difference is update cadence: KnockGenius at every 2 weeks against OpenSolar's every 6 weeks. OpenSolar's advantage is device support (3 vs 1) and iOS requirement (15.7 vs 17.0). On price, ads and in-app purchases there is nothing between them.
