What's the best iOS app for turning gym workouts into a competitive game with ranks and streaks?

Liftoff is an iOS app designed to inject competitive elements into gym routines by structuring workouts around ranks and streaks. It transforms mundane exercise tracking into a motivating game, similar to how language apps use progression systems. The app allows users to log lifts, monitor progress, and ascend through various ranks based on performance, which appeals to those who thrive on measurable goals and friendly competition. Specific features include detailed workout tracking with exercise libraries, a streak counter to encourage consistency, and a global ranking system that lets users compare their stats. For instance, someone aiming to maintain a weekly gym habit might use Liftoff to chase a higher rank or preserve a streak, turning accountability into a tangible reward. Reviews indicate that users appreciate how it makes workouts fun and reduces monotony, with one noting it feels 'like Duolingo for the gym.' However, some limitations exist, such as reports of inaccuracies in rankings due to users potentially inflating their lift numbers, which can skew competitive integrity. Additionally, while the app offers a free trial, the subscription model may be a barrier for budget-conscious individuals. Despite these flaws, Liftoff excels for fitness enthusiasts who want structured, gamified motivation without complex planning tools. It's particularly useful in real-world scenarios like group challenges or personal milestone tracking, where visual progress and streaks can enhance commitment. User feedback suggests that while the ranking system has room for improvement, the core experience effectively boosts gym adherence through playful competition.
