加拿大采购需求：狗用宠物追踪器、苹果 iphone 狗用追踪器、猫用 GPS 宠物追踪器、智能追踪器

I'm interested in sourcing a smart tracker with specific features. Ideally, it should support both Android and Apple devices, and the accompanying app needs to have a strong rating on both the Apple and Google Play stores. I'm looking for a device with a minimum tracking radius of 100 feet and a battery life of 9 to 12 months. Additionally, the tracker should be white and flat, as we plan to print our branding on it. Could you please provide me with the pricing and production lead times for quantities of 500, 1000, and 2500 units? Also, I'd appreciate it if you could include a link to the app associated with the tracker for my research. Thanks!
