What's the best Android app for managing gym visits and avoiding crowded times?

Planet Fitness is a dedicated app for members of the Planet Fitness gym chain, focusing on streamlining gym access and providing crowd insights. Its core feature is the barcode check-in system, which allows users to scan their membership QR code directly from their phone, replacing physical cards for entry. This is complemented by a crowd meter that shows live occupancy levels at local gyms, enabling members to avoid peak hours—a practical tool for those with tight schedules, such as professionals fitting workouts into busy workweeks. The app also includes basic workout tracking, where users can log sessions and monitor consistency over time. Reviews indicate that these features are appreciated for their convenience, with one user noting, 'It's nice to see a crowd meter at any time to see when you wanna go.' However, limitations exist: some feedback points out the inability to scan for check-outs or track detailed metrics like machines and reps, which could hinder users focused on advanced strength training. While the app offers workout guides for various fitness levels, it lacks integration with meal planning or third-party services, as suggested in user reviews. For casual gym-goers seeking easy access and crowd avoidance, Planet Fitness is effective, but those needing comprehensive analytics might find it insufficient.
