Freeletics vs Styrki

Freeletics offers personalized training across HIIT, calisthenics, gym and weight training, cardio, running, strength, and weight loss. Its Coach adapts training plans using personal information, preferences, and completed sessions. Training Journeys cover bodyweight, running, and weights, with goals such as endurance, speed, strength, muscle building, and weight loss. Workouts can be adjusted for time, equipment, noise, intensity, or body areas to exclude. The free Training app includes selected warm-ups, cool-downs, God Workouts, individual exercises, and runs; a Coach subscription unlocks all workouts, exercises, and runs and adds a structured plan. Freeletics lists an exercise library of 100 exercises and supports adaptive progression, custom workout plans, equipment profiles, and AI coaching. With permission, selected activity data can be exchanged with Apple Health and Google Health Connect; an optional Strava connection reads activity data with explicit consent. Freeletics is available on Android, iOS, and web. Its free plan costs nothing.

Styrki is an iPhone training app combining strength workouts and running with AI coaching tailored to recovery, strength curves, and volume tolerance. After each session, its AI recalculates weights, sets, and reps using training and recovery feedback. Running tools include GPS runs, heart rate tracking, and Norwegian 4×4 intervals; the app says it detects more than 20 types of lifting and running personal bests. The exercise library lists over 600 strength exercises, with video demonstrations, instructions, and muscle-targeting guides. Styrki lists two-way Apple Health integration and integrations with Apple Watch, Strava, Polar, and Oura. Apple Watch can start runs and stream live heart rate; Live Activities show pace and rest timers, and widgets show the Styrki Score and next session. The free plan includes manual logging, full personal-best tracking, GPS runs, cardio and heart rate, plus three AI workouts and five coach messages. Paid AI plans add unlimited workout generation and coach chat, while AI Voice adds live voice coaching. The company says training context, prompts, microphone audio, and transcripts may be sent to third-party AI providers to generate requested results.
