Trainia trains, eats, and logs with you It helps you understand how your training, nutrition, and movement work together. One app for everything you used to do across three: GYM AND TRAINING Generate plans from a photo, a PDF, a message from your coach, or a conversation. Every set matters — weights, reps, RPE, rest times, and techniques. If a resistance band replaced the cable machine, Trainia understands that. SPORTS AND MOVEMENT Run, swim, cycle, play football or padel. Import activity from Apple Health or log it manually. Every activity counts toward your calories, your weekly plan, and your progress. FOOD WITHOUT OBSESSION Scan a plate and get macros and calories without weighing every gram. Ask for nutrition plans that respect your allergies, budget, culture, and what you already have in the fridge. You can also bring your own. ONE CONNECTED STORY Your strength last week, what you ate today, and tomorrow’s run all live in the same place. Dori connects them to suggest what to adjust. PRIVACY Your data is yours. We do not sell your information or use ad tracking. Trainia works for free. Plus unlocks higher generations. Pro adds persistent memory and our most powerful AI model.

HeavyMuscle

Most gym apps just record what you already did. HeavyMuscle is the workout tracker & gym log that tells you what to do next — and does the thinking for you. An AI coach in two modes builds your weight lifting plan from a single sentence and reshapes each session around your injuries, equipment and recovery. Before you touch the bar, it shows the plates to load, generates your warm-up sets and pre-fills every set with your last numbers. Automatic PR detection and an estimated-1RM curve tell you the moment you get stronger. 873 animated exercises, a real rest timer and a recovery body map, in 6 languages. Create unlimited routines, log unlimited workouts, all offline from the first second. AI COACH • Two modes: Conversation for questions and adjustments, and Builder to generate a full workout plan from scratch. • Generates a full workout from a single sentence ("30 min chest workout without barbell"). • Snap a photo of a gym machine and it finds the matching exercise. • Adapts today's training to your injuries, available equipment and experience level. • Reviews your last session or the full week and gives objective feedback. WORKOUT LOG • Every set pre-filled with your last weight and reps — your previous numbers are right there at the rack. • Plate calculator: see exactly which plates to load per side, for barbells and dumbbells. • Time-based exercises: cardio, planks and circuits (AMRAP / for time) with a built-in timer. • Warm-up sets generated automatically, ramped to your working weight. • Rest timer with 3-2-1 beeps, vibration and a screen that stays on. • Warmup, drop-set, failure and cluster sets, plus supersets. • Quick Start, unlimited workout templates and retroactive logging. • Share a session as a post-ready image card (volume, sets, muscles). EFFORT & PROGRESSION (RPE/RIR) • Rate how hard each set felt — RPE or reps in reserve, one tap after the set. • Next time, the workout planner suggests the weight: up when it felt easy, down when it was a grind — always weights you can actually load. PROGRESS & RECORDS • Automatic PR detection with a record badge the moment you beat a best. • Estimated-1RM curve per exercise to see your strength trending over time. • Progress photos: capture, import and compare with a before/after slider. EXERCISE LIBRARY • 873 exercises with animated demonstrations, target muscles, equipment and difficulty. • Mark favourite and avoided exercises — the AI Coach factors them in. HISTORY & ANALYTICS • Recovery body map (front/back): see what's fatigued, recovering or ready to train. • Weekly volume per muscle as a body heatmap or ranked chart, with low/optimal/high zones. FULL PROFILE • Body measurements with dated history and goals — set a target and watch the gap close. • Water tracking: daily hydration goal, one-tap logging and reminders. • 10 injury zones with automatic exercise filtering. • Builder that respects your equipment, goal and experience level. APPLE WATCH • Your workout mirrors to your wrist — check off each set with a tap, pre-filled with your last numbers. • Adjust weight and reps with the Digital Crown; rest counts down with 3-2-1 haptics. • Live heart rate and calories, with a summary when you finish. Requires a paired iPhone. PRIVACY & OFFLINE • Works fully offline in anonymous mode: nothing leaves your phone until you sign in. • Optional Apple, Google or e-mail login syncs your gym log to the cloud. LANGUAGES • English, Portuguese (BR), Spanish, German, French and Italian. Whether you train for bodybuilding, powerlifting, strength training or hypertrophy, HeavyMuscle is the gym tracker that turns effort into progress.
