No, the Digivices [0] were a completely different toy: It lacked the caring aspect and used a pedometer to make progress in traveling the world, where on occasion you'd get an alert about encountering an enemy digimon. If you ignored it your Digimon would be injured and you'd have to heal it.
In addition, to get in on the craze, other companies made their own products that played identically to tamagotchis. Tiger Electronics had the Giga Pet brand [1], for example, from which I had the alien.
Quick edit: Ah wait maybe you meant these [2], which were before the Digivices. I never had one, don't know if they were more like tamagotchis.
