Styrki

Overview

Styrki brings strength workouts, running and AI coaching together. The AI recalculates weights, sets and reps for each session using training and recovery feedback, making the app a stronger fit for people who want their program to respond as they train than for those who only need a manual log. Runners are part of the intended mix: the app includes GPS runs, heart-rate tracking and Norwegian 4×4 intervals.

It also detects more than 20 types of personal bests across lifting and running, and includes the Styrki Score, a community feed and leaderboards. Those tools can help users follow progress across both activities, but they do not remove the Free plan’s tight allowance for AI coaching.

Key features

Adaptive workouts and coach memory

Session-by-session adjustments to weights, sets and reps are Styrki’s central advantage for people who want recovery feedback to inform training. Paid AI plans add unlimited workout generation and coach chat, adaptive learning, program adherence and periodization. The coach can recall earlier text chats and live voice sessions; deleting a conversation also deletes its stored memory. That continuity may suit people who want to build on prior coaching, while the deletion control offers a way to clear that context.

Running, records and exercise guidance

GPS runs, heart-rate tracking and Norwegian 4×4 intervals make Styrki relevant to people who train for both strength and running, rather than just a lifting tracker. Automatic tracking of 20-plus record types gives a broad view of progress across those activities. Its library of more than 600 strength exercises includes video demonstrations, instructions and muscle-targeting guides, which can help users find and understand movements without relying only on a workout log.

Connected devices and privacy

Styrki lists two-way Apple Health, Apple Watch, Strava, Polar and Oura integrations. Apple Watch can start runs and stream live heart rate; Live Activities show pace and rest timers, and widgets display the Styrki Score and next session. These connections make the app more useful to people already using those services and devices.

Styrki says it does not sell personal information or use HealthKit, Motion/Fitness, location, microphone or Bluetooth data for advertising or marketing. However, relevant training context, prompts, microphone audio and transcripts may go to third-party AI providers when needed to generate requested coaching or workout results. The privacy policy describes technical and organizational safeguards but does not guarantee absolute security. Users can request access, correction, deletion or a portable copy of personal data, and can delete their account in settings.

Pricing

Styrki is freemium, with a Free plan and two paid annual options. The Free plan is free and includes unlimited manual workout logging, full personal-best tracking, GPS runs, cardio and heart rate, the Styrki Score, community feed and leaderboards. It also allows three AI workouts and five coach messages. That is a substantial base for people who mainly log training and run, but the AI caps make it a poor fit for anyone expecting regular generated sessions or ongoing chat coaching.

Styrki AI costs 59.99 USD per year, billed annually ($59.99), with a 7-day free trial and a stated 50% saving. It includes everything in Free plus unlimited AI workout generation and coach chat, adaptive learning, AI program adherence and periodization, and an AI avatar and video coaching. This is the clearest fit for users who want ongoing AI programming without voice coaching.

Styrki AI Voice costs 41.67 USD per year, billed annually ($499.99), with a 7-day free trial and a stated 30% saving. It includes everything in Styrki AI, plus live voice coaching, spoken cues, RPE prompts and form tips, hands-free coaching, spoken Max Test coaching and voice sessions saved to coach memory. The spoken guidance may suit people who want coaching during training without reading prompts, but the annual billed amount is much higher than the AI plan’s. The published per-year price and billing amount for this plan do not match, so confirm the charge before subscribing.

Platforms

Styrki is available on iOS. That suits iPhone users, especially those using Apple Watch, but rules it out for people who need Android, web or desktop access.

Who it's for

Styrki is best suited to iPhone users who combine lifting and running and want workout adjustments based on training and recovery feedback. Its exercise library, record tracking and wearable integrations also give it range for people who want a connected training routine. Choose another app if you need a non-iOS platform, or if you want unlimited AI coaching without a paid annual plan.

Pros and cons

Pros

• Strength and running share one app, with GPS, heart rate and Norwegian 4×4 intervals for run sessions.
• AI adjusts weights, sets and reps using training and recovery feedback, rather than leaving all progression decisions to the user.
• The library has more than 600 exercises with video demonstrations, instructions and muscle-targeting guides.
• Apple Watch, Apple Health, Strava, Polar and Oura integrations connect the training routine to common fitness services and devices.
• The Free plan supports unlimited manual workout logging and full personal-best tracking.

Cons

• Free limits AI use to three workouts and five coach messages, which is restrictive for users who want frequent coaching.
• Styrki is iOS-only, excluding Android and web users.
• AI coaching may involve sending training context, prompts, microphone audio and transcripts to third-party AI providers.
• The AI Voice plan’s annual price is presented as 41.67 USD per year but its billing amount is $499.99 annually, a discrepancy to resolve before purchase.

Verdict

Choose Styrki if you use an iPhone, train across strength and running, and want recovery-informed adjustments alongside run tracking and wearable connections. Its main advantage is combining those activities with adaptive coaching; look elsewhere if you need another platform, want uncapped AI on a free plan or are uncomfortable with AI-related data sharing.
