Which iOS app should I use for following guided workout plans from different professional trainers?

Playbook is a fitness platform designed to connect users with professional trainers through structured workout programs. The core appeal lies in its variety; users aren't limited to one training philosophy but can choose from numerous certified trainers specializing in different disciplines like HIIT, pilates, strength training, and yoga. Each plan includes detailed video demonstrations, often with the trainer personally guiding each movement, which helps ensure proper form. For someone building a home gym routine, this provides the structure and variety of a boutique studio without the recurring high cost. A common use case involves selecting a 4-week program from a preferred trainer, following daily sessions that require minimal equipment, and tracking completion. Reviews indicate high satisfaction with the instructional quality and the app's ability to maintain engagement through diverse content. A notable limitation is the lack of live, interactive sessions, positioning it more as an on-demand library than a real-time coaching service. The interface is generally praised for simplicity, though occasional users note that navigating between different trainer catalogs can feel slightly disjointed. For the subscription price, the volume of available content is frequently highlighted as a key strength.
