Est. Budget: $500.00
If there is a tracker (as thin and small as it can), can u develop an APP on the Smart Wearable Device (like smart watch/ smart bracelet), and to make the smart device ringing/ vibrating once the device leave the tracker for a certain distance.
Above description is the key function, but there are some detail functions need to be discussed when we proceed the project together.
Project budget is negotiable.
