S-Load is the strength training app built for lifters who want to see their progress, exercise by exercise, in an interface that makes them want to open the app every day. DAILY ESSENTIALS You log your sets. The app handles the rest. Weekly volume per muscle, set by set. Yearly adherence calculated day by day. Records detected automatically, on weight and on reps, and celebrated the moment you validate the set. A session score out of 100 that quantifies what you just did and places you on a visual tier scale. Some tiers are rarely unlocked. For every exercise: your progress curve, your best result, your full history. Your last performance sits right under each set while you train. At a glance, you know exactly where you stand. THE LAB New in 1.1. A page that reads your workouts for you. Your calorie target moves with your weigh-ins, your macros follow. A verdict on every exercise: improving, stalling or slipping. Your muscle balance month by month, your smoothed weight trend, your SBD total in validated loads. You compose it yourself: every module can be turned on or hidden. PROGRAMS Four calibrated programs ready to use: Push Pull Legs 3-day, Upper/Lower 4-day, Full Body 3-day, Hybrid PPL 6-day. Or build your own: exercises, sets, reps, rest, supersets. A library of 160+ movements organized by muscle, with form guides and demo videos, plus your own custom exercises. Export a program via QR code, import a training partner's. Edit it whenever you want. Program building was designed to be fast, not to feel like a spreadsheet. TRAINING MODE The moment you start, the whole app turns red. The rest timer starts on its own, your loads from last time are already in place. Live Activity and Dynamic Island keep the timer in sight. A free workout counts toward your week, even in a different gym. Everything works offline and syncs when you're back online. AN INTERFACE WORTH THE OPEN Native iOS 18. Permanent dark mode, no light mode ever. Polished animations, precise haptics, refined typography. iPhone widgets show your week and your volume per muscle without opening the app. The Lock Screen widget starts a session in one tap. 131 achievements, badges, session sharing to stories in three styles. The app takes your seriousness seriously. PREMIUM The essentials are free. Premium unlocks unlimited programs and custom exercises, the full exercise library, progress curves, the complete Lab, QR code program sharing and 5 alternative icons.

Grav is a strength tracker built for one thing: logging your weightlifting sessions fast, so you can focus on training instead of your phone. Tracking a workout should be effortless when it goes to plan โ and quick to adjust when it doesn't. Changed the weight or reps on a set? Adjust it with a quick wheel instead of typing the whole value from scratch, and your following sets carry that change forward automatically. One adjustment, not the same edit over and over. Grav does the small things well and gets out of your way. WHAT MAKES GRAV DIFFERENT - Faster logging โ quick wheel adjustments and sets that follow your changes mean you log a set in seconds, whether you're lifting to plan or pushing past it. - Bring your history with you โ switching from another workout app? Import your past workouts and keep your progress, records and charts from day one. - Personal records as they happen โ a trophy marks the set that beats your best 1RM, weight or set volume while you train, and every past record stays tagged in your history. - Routines with dynamic weights โ your working weights adjust to your recent performance every time you start a routine. Hit a new max and your next session moves up on its own, no manual updates. - Smarter supersets โ log a full round in a single tap when nothing changes, so circuits stop being a chore. - Charts that show real progress โ alongside volume and 1RM charts, Grav adds views like weight-vs-reps scatter and per-set bar charts, so you can actually see whether you're improving or stuck. - Compare without leaving your workout โ see your current set against last time, your plan, or your best, and switch between them instantly while you train. - Body measurements & health data โ track arms, legs, waist, chest and more, with body fat, lean mass, BMI, and recommended macros calculated for your goal. - Fitness challenges โ create a daily challenge, invite friends, and keep each other consistent. Whether you're focused on powerlifting, hypertrophy, or just staying consistent in the gym, Grav keeps logging out of your way. COMING SOON Apple Watch app. Assisted workout builder.

Verdict
The clearest difference is in-app purchases: Grav at none against S's 2. S's advantage is update cadence (every 3 days vs every 10 days). On price, ads, device support and iOS requirement there is nothing between them.
