CrewFit is the fitness app built for airline crew — the people who land in a new city every other day, sleep in a different hotel every night, and have 45 minutes between flights to figure out what's possible in the hotel gym. Every hotel gym is different. Some have a full rack and dumbbells to 100 pounds. Others have one bench, two resistance bands, and a sad treadmill. CrewFit's strength workout library is tagged to over 1000 hotels worldwide, so when you walk into the gym, you pick a workout that's actually doable with the equipment that's actually there. THE THREE PILLARS CrewFit— 2,000+ strength workouts auto-tailored to your current hotel's equipment. Full body, upper body, and lower body splits with set-by-set logging, video exercise demos, and a "Short Turn" button that compresses any workout into 30 minutes when you're tight on time. Track your reps, weights, and progress over time. CrewRun — GPS-mapped running routes near every hotel, published by real crew. Browse routes by hotel, see route maps, distance, ratings, and how many other crew have completed each one. Tap Start Run to begin GPS tracking. Publish your own routes after running them and earn Crew Points when others use them. CrewNutrition — Daily calorie, macro, and water tracking designed for crew managing performance and recovery on the road. Log meals, track water in ounces against a daily goal, and visualize protein, carbs, and fats against your daily targets. EARN AS YOU GO Every approved CrewRun route earns you 10 Crew Points. Redeem 100 Crew Points for a free month of CrewFit+, or 60 Crew Points for a free month of CrewNutrition. The more you contribute to the library, the longer you train for free.

Verdict
The clearest difference is in-app purchases: SkinIO at none against CrewFit+'s 5. SkinIO also leads on ratings volume (63 vs 3). CrewFit+'s advantage is rating (5.0 vs 4.6) and update cadence (every 10 days vs monthly). On price, review sentiment, ads and device support there is nothing between them.

CrewFit+ holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: SkinIO has 63 ratings behind it against 3, so its average is the more settled of the two.

SkinIO ships an update monthly, CrewFit+ every 10 days. The most recent releases landed on October 20, 2026 and October 5, 2026 respectively.
