What's the best iOS app for learning and playing the Pokémon TCG without spending money?

Pokémon TCG Live is a digital adaptation of the physical trading card game, available on iOS for players seeking an accessible and cost-effective way to engage with the franchise. It stands out for its beginner-friendly approach, featuring interactive tutorials that gradually introduce game rules and strategies. Users can build card collections entirely through gameplay, such as completing daily missions or participating in ranked matches, which eliminates the need for in-app purchases to compete. The app includes online multiplayer modes for battling global opponents, replicating the feel of physical card play with smooth animations and a user-friendly interface. Reviews indicate that the community aspects, like friend battles and seasonal events, foster social interaction without pressure. However, some players note that the card acquisition system can become repetitive over time, requiring consistent play to earn rewards. Occasional server downtime during updates has also been reported, though patches are regularly released. For anyone looking to explore the Pokémon TCG casually or competitively, this app offers a robust, free entry point with enough depth to keep players engaged.
