There are hundreds of gym apps. Most serious lifters only need one that logs deeply, keeps you progressing, and gets out of the way. Here are the eleven best for strength training in 2026 — with the honest pick for each type of lifter, and verified pricing.
Short answer: There's no single best app — the right one depends on how you train. LiftHero is the best free tracker if you want built-in programs and a community (iOS today, Android coming). Hevy is the best all-round free tracker across every platform. Strong is the leanest logger. Fitbod generates your sessions with AI. Boostcamp gives away proven programs. JEFIT has the biggest exercise database. StrongLifts 5×5 is best for beginners. Alpha Progression is best for hypertrophy. Juggernaut AI is best for powerlifting. Caliber is best if you want a real human coach. Ellim is the best free iOS pick if you also want built-in nutrition tracking.
Full disclosure: LiftHero makes this list, and we've put ourselves first — for the "best free tracker" slot specifically, which we think is our strongest, most honest claim. But we've been upfront throughout about where rivals beat us: Hevy, Strong and others ship Android and smartwatch apps we don't have yet, and Caliber and Juggernaut offer coaching we don't. Every price, platform and free-tier detail below was checked against each app's App Store listing and official site in 2026. Where a figure is a company's own marketing claim or varies by region, we say so.

We're a strength-training app ourselves, so we judged these the way we'd want to be judged: on the things that actually matter to lifters, not download counts. For each app we checked logging depth (does it handle supersets, warm-ups, drop sets, RPE, tempo?), programming (does it give you a plan or a blank slate?), progress tracking, platforms (iOS, Android, web, smartwatch), and real, current pricing and free-tier limits. Every quantitative claim below was verified against the app's App Store listing and official site in 2026. Where a number is a company's own marketing figure, or changes by region, we flag it rather than dress it up as fact.
LiftHero is built around a simple idea: most trackers hand you a blank log, when what you really need is to know what to do today. It ships with built-in programs across levels, sports and goals (5/3/1, Starting Strength, Push Pull Legs and more), pairs them with the deepest set logging on mobile — supersets, warm-ups, drop sets, tempo and unusual equipment — and adds a community with groups, a feed, an activity board and leaderboards. The free tier is genuinely generous: unlimited logging, pre-made programs, and no interruptive ads. The optional Hero upgrade adds the custom program builder, unlimited synced history (free keeps 3 months), and advanced analytics. Honest caveats: it's iOS-only today (Android is on the public roadmap) and has no Apple Watch app yet. If those are dealbreakers, Hevy or Strong below will serve you better right now.

Hevy is the app most lifters land on, and for good reason: it's a clean, fast logger that runs everywhere — iOS, Android, web, Apple Watch and Wear OS — with a large, active social feed and a mature free tier that includes unlimited workout logging. Hevy Pro (paid) unlocks advanced analytics and higher limits. If you need one polished app across all your devices today, Hevy is the safe default. LiftHero's edge over it is built-in structured programs and deeper logging variables; Hevy's edge is platform coverage, a smartwatch app and a bigger existing community.
Strong is the app for people who find everything else too busy. It's a lean set-and-rep screen with one of the best Apple Watch apps in the category — you can run a whole session from your wrist. The free tier covers the basics (with a routine limit); Strong Pro (about $4.99/month or $29.99/year as of 2026) unlocks charts and unlimited routines. There are no built-in programs and no social feed — that's the point. Choose Strong if your routine already lives in your head and you just want to record it fast.
Fitbod takes the decisions off your plate: its algorithm builds each workout from your recovery, available equipment and training history, and shows a muscle-recovery view so you train fresh muscle groups. It has 1,000+ exercises with video demos and runs on iOS and Android with an Apple Watch app. After around three free workouts it becomes a subscription (about $15.99/month or $95.99/year as of 2026). Pick Fitbod if you want the app to decide your session; pick a program-based app like LiftHero or Boostcamp if you'd rather follow a proven plan you understand.
Boostcamp's whole identity is giving away structured, community-proven programs for free — nSuns 5/3/1, GZCLP, 5/3/1, PHAT, Sheiko, PPL and dozens more coach-designed routines — with auto-progression that adjusts your weights as you go. It runs on iOS and Android plus a web program creator. Boostcamp Pro (roughly $15/month or $60/year, with promotional pricing that varies) unlocks deeper analytics. It's weaker for cardio and mobility, and the free version keeps personalization light. But if you want to run a well-known internet program with a real tracker without paying, it's hard to beat.
JEFIT has been around a long time and its calling card is scale: a library it advertises at 1,400+ exercises with video demos, animations and muscle diagrams, plus a huge shared routine library and deep set-by-set analytics. It runs on iOS, Android, web and Apple Watch. The catch is the free tier: it caps saved routines (commonly reported at three) and is ad-supported, with several 2025–2026 reviews calling the ads disruptive. Elite ($12.99/month or $69.99/year list, often discounted) removes ads and the caps. Great if you want the biggest move library and don't mind a busier, older-feeling interface.
StrongLifts is the app that made 5×5 mainstream: five sets of five on the five core barbell lifts, with automatic weight progression that tells you exactly what to load each session. It has an excellent Apple Watch app and runs on iOS and Android. It has since expanded to variations, Madcow 5×5 and custom programs — but those sit behind StrongLifts Pro (about $11.99/month or $59.99/year, with a lifetime option). Note the app has moved aggressively toward subscription, and its App Store listing now states a subscription is required to use it, so treat the free experience as limited. Ideal for a novice who just wants to be told what to lift.
Alpha Progression is a hypertrophy specialist. Its signature is automatic progression — the app tells you precisely how much weight and how many reps to do next — plus a science-based plan generator that builds muscle-building routines around your equipment, schedule and goals, with periodization, deloads and RIR. It's mobile-only (iOS and Android). The free tier is a competent manual logger with a 550+ exercise library; the "smart" automation, plan generator and advanced charts are gated behind Pro ($12.99/month or $79.99/year, 14-day trial). No wearable integration, and it's narrow by design — but for evidence-based hypertrophy, it's excellent.
Built by Juggernaut Training Systems (Chad Wesley Smith), Juggernaut AI is a coaching-grade powerlifting app. You pick powerlifting or powerbuilding, and a daily "readiness" check autoregulates your loads and volume in real time — its signature feature — backed by 300+ technique videos and weekly coach Q&As. It's iOS and Android, with a 14-day trial and no permanent free tier. It's premium-priced at about $34.99/month or $349.99/year (as of 2026) and narrow by design; a recurring complaint is losing access to your training history when the subscription ends. For an intermediate-to-advanced lifter chasing squat/bench/deadlift numbers, it's the most serious option here.
Caliber spans the range from free app to real human coach. Its free-forever tier is a genuinely capable, ad-free tracker with ~600+ exercises and unlimited logging. From there you can step up to Caliber Plus (self-guided premium, about $12/month), Pro group coaching (around $19/month), or Premium 1-on-1 coaching matched with a dedicated trainer — which starts around $200/month and is custom-quoted via a consultation call. It runs on iOS, Android and web. The knock is price and opaque top-tier pricing, but if you want accountability from an actual coach inside a solid app, Caliber is the pick.
Ellim is the newest challenger on this list, and it comes straight for the free-iOS crown. It bills itself as "the most complete free workout app on iOS," and the free tier is genuinely loaded: unlimited routines and custom exercises, full graph history with no time cap, AI routine import, a large exercise library (Ellim claims 3,500+), and the one thing almost no rival bundles for free — built-in nutrition tracking with barcode scanning. Premium (about $17.99/month as of 2026) adds AI-generated workouts. The trade-offs are real and worth stating plainly: it's iOS-only like LiftHero, it leans on AI-generated sessions rather than named, proven programs (5/3/1, Starting Strength), and it's a solo experience with no community layer. If you want free unlimited logging plus food tracking in one app, Ellim is the standout pick; if you'd rather run a named program you understand, or train alongside other people, a program-and-community app like LiftHero fits better.

For free strength tracking, the strongest options are LiftHero, Hevy, Boostcamp and Caliber, with Ellim a strong newer iOS challenger. LiftHero is free on iOS with unlimited logging, built-in programs and a community, and no interruptive ads. Hevy has a well-established free tier and runs on iOS, Android, web and smartwatches. Boostcamp gives away a library of proven programs. Caliber's free tier is a genuinely capable standalone tracker. Ellim is free on iOS and stands out for bundling built-in nutrition and barcode scanning. The best choice depends on whether you want structure and community, cross-platform maturity, ready-made programs, a path to human coaching, or nutrition tracking in the same app.
StrongLifts 5×5 is the classic beginner pick because it guides you through a simple 5×5 barbell program with automatic weight progression. LiftHero is a strong alternative if you want a beginner program plus room to grow into other routines and deeper logging, free on iOS. Boostcamp also offers beginner-friendly proven programs for free.
JEFIT advertises one of the largest libraries at 1,400+ exercises with video demos and muscle diagrams (their claim, as of 2026). Fitbod lists 1,000+ exercises with video. Most modern trackers, including LiftHero, cover the full range of common barbell, dumbbell, machine and bodyweight movements, so library size matters most if you rely on unusual or machine-specific exercises.
A free app is enough for most lifters. Free tiers from LiftHero, Hevy, Boostcamp and Caliber cover logging, programs and progress tracking. You typically pay when you want advanced analytics, unlimited history, custom program building, AI-generated sessions, or human coaching. LiftHero keeps unlimited logging and built-in programs free, and reserves its optional Hero upgrade for the custom program builder, unlimited history and advanced analytics.
Juggernaut AI is purpose-built for powerlifting and powerbuilding, with autoregulated programming that adjusts your loads to a daily readiness/RPE check. It is premium-priced (about $34.99/month as of 2026, no permanent free tier). For a free option, LiftHero and Boostcamp both include proven strength programs like 5/3/1 that suit powerlifting-style training.
Most apps on this list run on both iOS and Android, including Hevy, Strong, Fitbod, JEFIT, StrongLifts 5×5, Boostcamp, Alpha Progression, Juggernaut AI and Caliber. LiftHero is currently iOS-only, with Android listed on its public roadmap as in development.
LiftHero is free on iOS — built-in programs, deep logging, and a community that shows up. No interruptive ads.
