The Martian Notifier is a smartwatch, produced by smartwatch manufacturer Martian, that's about substance rather than flash. This watch doesn't look too different from a regular watch with the exception of its small horizontal screen.
The Martian Notifier uses vibrations to send users notifications. This isn't unique in itself, but what is unique is the way it sends notifications. It actually allows users to customize unique vibration patterns for different kinds of notifications.
Like most other smartwatches, the Martian Notifier also allows you to choose which apps you want to receive notifications from. Another useful feature is the ability to view your notification history, which is helpful in case you miss a notification.
At only $129, the Martian Notifier is one of the cheapest smartwatches out there and represents a good option for the smartwatch enthusiast on a budget.
