The Best Fitness Apps for Android, iOS and Apple Watch in 2025

Choosing between apps for strength training gets easier when you separate the job they do. Some apps build the workout for you, some guide you through a coached plan, and some are basically high-quality gym logs. If you want the fundamentals behind good programming, the Core Principles & Techniques for Every Lifter guide is a useful companion. In this roundup, I am focusing on apps that actually help you lift better, whether that means adaptive workouts, coach-led sessions, fast logging, or clearer progress tracking. The best pick depends on your goal, equipment, budget, and how much structure you want before you walk into the gym.

What to look for in an app for strength training

A good strength app should save time, not create extra work. Look for one of three things: structured programming that matches your goal, a fast way to log sets and reps, or enough feedback to show whether you are progressing. The stronger options usually let you work with your available equipment, track metrics like volume or 1RM, and add coaching cues or videos when you need form help.

1. Fitbod

Fitbod is one of the best apps for strength training if you want the workout itself to be generated for you. The current site says it personalizes sessions based on your goals, fitness level, available equipment, training history, muscle recovery, and workout duration. Its FAQ also says you can set preferred workout length, and it tracks PRs, estimated strength, volume trends, training streaks, video demos, and step-by-step coaching cues. The current membership page lists $15.99 monthly or $95.99 yearly. (fitbod.me)

That makes Fitbod a good fit if you want less planning and more automatic programming. It is especially handy for home gyms or mixed-equipment setups because the plan changes around what you have available. If you like choosing every exercise yourself, a log-first app may feel simpler. (fitbod.me)

2. Ladder

Ladder is the pick for people who want a coach-style experience without building their own plan from scratch. Ladder says members get a daily workout plan created by an expert coach and updated each week, plus 5+ new workouts weekly, in-ear coaching, video demonstrations, precise pacing, and rep and weight tracking. The site also says there is no credit card to start and that members can try a free 7-day trial. (joinladder.com)

In practice, that makes Ladder a strong match for busy lifters who want structure and accountability more than endless customization. If you want someone else to tell you what to do today, then come back next week with a fresh plan, this is a very clean option. (joinladder.com)

3. Caliber

Caliber is a strong choice if you want science-based training with a coaching layer on top. The company describes the app as a top-rated free gym tracker and fitness app with 100+ strength and mobility plans, 700+ exercises, flexible planning tools, workout logging, progress analytics, community features, and expert guidance. Its main site also says you can upgrade to one-on-one coaching. (caliberstrong.com)

That mix makes Caliber feel like the middle ground between a simple tracker and a fully managed coaching program. It is a good fit if you want the app to guide your training, but you still want room to understand the why behind the plan. (caliberstrong.com)

4. JEFIT

JEFIT is one of the most feature-rich apps for strength training. Its planner pages say you can build custom routines from 1,500+ exercises, use ready-made plans like 5x5, PPL, or full-body, and sync across mobile, watch, and web. The app also tracks sets, weights, supersets, drop sets, notes, rest timers, volume, PRs, and 1RM, and the current pricing page shows a free Basic tier plus Elite at $12.99 per month or $69.99 per year. (jefit.com)

If you like to fine-tune your training, JEFIT gives you a lot of room to do that without starting from zero every week. It is especially useful if you already follow a split and want a bigger toolkit for planning, logging, and analyzing your progress. (jefit.com)

5. Strong

Strong is the best fit for lifters who want the app to get out of the way. The homepage describes it as a simple, intuitive workout tracking experience, and says it is available on iPhone, Android, and Apple Watch. It also lists features like supersets, custom exercises, CSV export, Apple Health, warm-up calculator, Siri Shortcuts, RPE, advanced charts, workout scheduling, muscle heat map, workout sharing, and custom timers. Strong says accounts are free forever, with Strong PRO available for deeper progress tracking. (strong.app)

That combination makes Strong a smart choice if you already know your routine and just need a clean place to log it. It is a log-first app in the best sense, fast enough for the gym and detailed enough to stay useful over time. (strong.app)

6. Nike Training Club

Nike Training Club is the easiest recommendation if you want guided workouts without paying for a heavy coaching app. Nike's help pages describe class-style workouts led by trainers in real time, multi-week programs, guidance on nutrition, sleep, and mindset, and workout scheduling with casting to a bigger screen. Regional NTC pages also say the library includes more than 200 free workouts and programs across strength, endurance, yoga, and mobility, with sessions ranging from 5 to 50 minutes. (nike.com)

That makes NTC a good fit for beginners or general fitness users who want structure, but not a traditional lifting log. If you want a guided session that feels approachable and easy to start, it is one of the simplest ways in. (nike.com)

7. Setgraph

Setgraph is worth a look if your main priority is fast logging. The official site says it is a workout log app that makes it easy to log workouts, track progress, and stay consistent. It highlights quick set logging through swipes or workout history, real-time comparison with your last session, a workout planner, an AI workout generator, a built-in rest timer, and support for more than 70 activities. Setgraph also says it is trusted by 67,000+ lifters. (setgraph.app)

If you prefer to keep the workout moving instead of tapping through menus, Setgraph is a practical choice. For a closer look at what users say, read the Setgraph App Reviews (2025). (setgraph.app)

How to choose between these apps

The simplest way to decide is to match the app to the kind of decision you want to remove from training. If you want the app to pick the session, start with Fitbod or Ladder. If you want coaching and accountability, Caliber is a strong fit. If you like building your own plan and analyzing the data, JEFIT offers the deepest toolbox. If you already know your split and just want a clean log, Strong or Setgraph will probably feel best. If you mainly want a free guided workout library, Nike Training Club gets the job done.
