Our verdict on Styrki
Styrki is an iPhone fitness app for strength training and running. It generates personalized workouts, adjusts weights, sets, reps and progression from training feedback, and tracks recovery, personal records and running performance. The app combines a 600+ exercise library with video demonstrations, GPS running, heart-rate tracking, Apple Watch support and Apple Health synchronization. It is suited to people who want structured strength training with AI guidance, while runners can also use its pace, interval and heart-rate features.
The pricing structure starts with a Free plan that includes unlimited manual workout logging, GPS runs, cardio and heart-rate tracking, Styrki Score, a community feed and leaderboards, plus 3 AI workouts and 5 coach messages. Styrki AI is listed at $5 per month when billed annually and adds unlimited AI workout generation, unlimited coach chat, adaptive learning, program adherence and periodization, and AI avatar and video coaching. Styrki AI Voice includes those features plus live voice coaching, spoken cues, RPE prompts, form tips and saved voice sessions. It is listed at $41.67 per month when billed annually; monthly pricing is $59.99, and annual pricing is $499.99 in the US App Store listing. A 7-day free trial is available.
Integration is a clear part of Styrki’s appeal for Apple-focused users. Apple Health supports two-way synchronization, while Apple Watch offers a companion experience and Live Activities. The app also connects with Strava, Polar, Oura and Bluetooth heart-rate straps. Automatic personal-record detection, equipment profiles, adaptive progression and coach conversation memory add structure beyond basic logging. The main constraint is platform availability: Styrki is iOS-only. Choose it for low-cost, adaptive strength coaching and optional spoken guidance within an Apple-centered setup; choose an alternative if Android support or a lower-cost live voice tier is essential.
