The best workout apps are the ones you are still opening in week six, after the January energy is spent. After training on nine of them for weeks past the six-week mark, our picks are the Peloton App for class motivation without the hardware, Nike Training Club as the free heavyweight, and FitBod for strength programming that adapts as you lift. The rest earn specific niches, from human coaching to free running plans.
One thing up front: an app cannot see your form or read your training history. Every pick below is a programming and motivation tool, not a coach who has watched you move. If you have an injury or a health condition, get a clinician's all-clear before starting anything here.
How We Tested These Workout Apps
We paid for every subscription at full price and trained with each app for at least six weeks, long enough for the novelty to wear off and the programming to show its depth. We followed the programs as written and tested the failure cases: what the free tier actually gates, how hard cancelling is, and what a skipped week does to the plan.

Prices here change often, so verify current pricing before committing. Here is what each app was like to live with.
1. Peloton App - Best for Class Motivation Without the Hardware
The Peloton App is the cheapest way to buy what made the bikes famous, and what made them famous is not the bike. Weeks of classes on our own equipment confirmed the instructors, music, and schedule survive the jump to a phone screen, and the app tiers cost far less per month than the All-Access membership tied to the hardware.
Where it wins and hurts: when someone on screen counts your last four reps, you do four more, and it produced our most consistent training frequency here. But the class rotation repeats for regulars, its best content assumes some equipment, and the trial gates most of the library quickly.
Our take: the Peloton App is the value play, and our Peloton review covers when the hardware is worth the upgrade.
2. Nike Training Club - Best Free Workout App, Honestly
Nike made Training Club fully free, and the honest reason is that the app is a brand advertisement. That is a trade, not a catch: you get structured multi-week programs, guided strength sessions, and short bodyweight workouts. We ran one program for weeks and found the progression genuinely built rather than shuffled.
Where it wins and hurts: no paywall, no expiring trial, no hostage features, and for a beginner following a real multi-week plan at zero cost, nothing else competes. But the plan is fixed once you start, with no adaptation to what you lifted, and advanced lifters will find the ceiling low.
Our take: start here if money is the barrier; our Nike Training Club review goes deeper.
3. FitBod - Best AI Strength Programming
FitBod answers the question Nike Training Club leaves open: what should I lift today? You feed it your equipment, and each session is generated from your logged history. Sore muscle groups get backed off, weights progress from your last sets, and the plan adjusts when you skip a week.
Where it wins and hurts: it respects what you actually did and handles awkward setups, hotel gyms and odd dumbbells included, better than any fixed program. But the free tier allows only a few workouts before the gate, and nobody is checking your squat depth.
Our take: the pick for lifters who want progressive overload handled for them, paired with basic equipment from our home gym guide.
4. Caliber - Best for Real Human Coaching
Caliber starts as a free workout tracker, but the reason it is here is the paid tier: you match with an actual human coach who builds your program, reviews your logged weeks, and answers messages. Weeks on the coaching tier produced the feedback loop no algorithm can fake: form notes from video you send in, and the pressure of a person expecting your check-in.
Where it wins and hurts: accountability with a brain attached, at a monthly cost well below most in-person training. But coaching is one of the priciest lines on this page, the free tier is basic, and coach quality varies.
Our take: if a fixed program has failed you three Januarys in a row, the problem may be accountability, and this is the honest fix.
5. Strong - Best Lift-Logging App for Progressive Overload
Strong does almost nothing, and does it perfectly: you log sets, reps, and weight, it restates your last performance so you know what to beat, and charts show whether the numbers are climbing. Weeks of logging confirmed that the core loop of strength training survives beautifully in app form, and the free tier is generous enough that many lifters never need Pro.
Where it wins and hurts: logging a set takes seconds, the rest timer is automatic, and the free version is not a demo like most freemium apps. But it logs progress, it does not create it, so if you do not know what your week should look like, start with a programming app.
Our take: the best second app here. Alpha Progression is the closest rival if you want more built-in progression suggestions.
6. Nike Run Club - Best Free Running App
Nike's running app pairs audio-guided runs with genuine training plans for 5Ks through half marathons, all free. Weeks of guided runs found the coaching audio well produced, the GPS accurate against known routes, and the plan logic sane when we skipped a day.
Where it wins and hurts: guided runs that actually teach pacing, plus plans that adapt to missed days without a subscription. But there are no advanced analytics, so serious runners outgrow it toward Garmin's ecosystem, and the phone has to come along unless you pair a watch.
Our take: the default first running app; if running becomes your sport, Garmin Connect takes over the analytics.
7. Down Dog - Best Cheap, Customizable Yoga and Mobility
Down Dog generates a fresh yoga session every time instead of replaying a fixed library, and every variable is adjustable: length, level, pace, focus, even the music. Weeks of mobility work solved the two classic objections to yoga apps, boredom and being locked into someone else's flow. One cheap subscription also covers its sibling apps.
Where it wins and hurts: a six-minute pre-run flow and a forty-five minute session come from the same app, generated fresh each time. But there is no real free tier beyond the trial, and no app can see whether your knees are doing something a clinician should know about.
Our take: the best value in flexibility training here, and likely to survive week six because it never repeats exactly.
8. FitOn - Best Free App for Short Workouts
FitOn is built around the workout you do when you will not do a workout: ten to twenty minute bodyweight sessions, filterable by time and focus. The free tier is unusually generous, and weeks of lunch-break sessions confirmed the short format gets used on days nothing else would.
Where it wins and hurts: when the choice is FitOn or nothing, FitOn keeps the habit alive, which is the whole game in week six. But short sessions do not build serious strength.
Our take: stack it on top of a strength pick for the days that would otherwise be skipped.
9. Future - Best When You Want a Coach Who Builds Everything
Future sits at the top of the price ladder: a dedicated coach designs every week of your training, adjusts it against Apple Watch data, and checks in like a trainer who never forgets a session. It was the most tailored experience here, at a premium price with no meaningful free tier.
Where it wins and hurts: every workout is waiting, built for you, and the coach sees compliance, so skipping gets noticed. But this is the priciest habit on the page, and it leans on Apple Watch pairing.
Our take: right for people with money and zero desire to program for themselves, wrong for everyone else; Caliber is the cheaper step into human coaching. Either way, a remote coach cannot see your form live.
Which Workout App Survives Week Six?
The pattern was simple: apps with structured progression, like FitBod, Strong, Caliber, and Future, were still in use when the novelty died, because they showed measurable progress even on unmotivated days. Video-library apps survived on variety, until the rotation repeated, and the free picks survived on costing nothing. Our guide to staying consistent past week three and our workout splits explainer cover the rest of that framework.
The bottom line: most people should start free with Nike Training Club, add FitBod or Strong once bodyweight stops being enough, and only pay human-coaching money to Caliber or Future if a lack of accountability, not a lack of information, is what keeps breaking the habit.
