Freeletics

Based on current reviews and testing, here's a rundown of the most popular and highly-rated workout apps across different categories:

Strength Training & Workout Tracking

• Jefit — Frequently ranked as the most complete tracker, offering 1,400+ exercises with demos, AI-driven progressive overload, and adaptive training. It's considered ideal "if you want complete tracking, AI-guided progression, and a system that tells you whether your training is actually working."
• Hevy — A favorite for its social features; it's the pick "if you value a free social experience and accountability over advanced analytics."
• Strong — Loved for simplicity: it "wins if you want the fastest possible logging with no distractions — and you already have your own program."
• Fitbod — Good if you want "automated variety and muscle-recovery-based recommendations."
• StrongLifts 5x5 — Great for those who want "a dead-simple barbell program with zero decisions."

All-in-One / Coaching Apps

• Caliber — Named a top overall pick by Fortune, combining "science-based programming combines strength and cardio for an all-purpose workout routine designed to get results," nutrition tracking, and 1-on-1 coaching for added accountability.
• SHRED — Praised as "the best workout app for strength training thanks to its highly" rated training routines from certified trainers and athletes.
• Nike Training Club — A long-standing, widely used free option praised for its broad workout library.

Studio-Style / Class-Based Apps

• Apple Fitness+ and Peloton — These remain go-tos for "coach led classes, polished videos, and variety, especially for home workouts with minimal gear." Testers found them "best used as supplements: great for cardio days, active recovery... less ideal as the sole platform if you want your first three months of training to be intentionally structured."

AI-Driven Bodyweight/HIIT

• Freeletics — Known for tough bodyweight training; it "uses AI to adapt high intensity workouts to your current fitness level, focusing heavily on conditioning and bodyweight strength." Better suited to those with some existing fitness base rather than complete beginners.

Combined Strength + Cardio

• Peloton, Fitbod, Hevy, Strava and newer entrant Edge are commonly compared for blending lifting and cardio into one coherent plan, since true integration means the app understands how your strength sessions and cardio sessions interact, programs heavy squat days away from long runs, reduces lifting volume during high-mileage weeks, and manages total training stress across both modalities.

Quick Recommendation by Use Case

Most of these apps offer free tiers or trials, so it's worth testing 2-3 that match your goals (strength vs. cardio vs. all-around) before committing to a subscription.

Top workout apps in 2026 cater to strength training, HIIT, low-impact fitness, and personalization, with popular choices including Caliber, Boostcamp, TR (AI)NER, and BetterMe.
