After the relative failure of the first-generation, Android-based Galaxy Gear, Samsung tried again with the Gear 2. Aside from dropping "Galaxy" from the name, Gear 2, released in April 2014, shows several notable changes. The $300 watch sports an improved design, a heart-rate monitor, basic fitness tracking, improved notifications, and it is water resistant. However, the smartwatch runs the Linux-based, open-source Tizen OS, it has limited apps and can only be paired with certain Samsung smartphones. The Gear 2 is identical to the Gear 2 Neo, but the latter costs $100 less and lacks the Gear 2's camera.
