TRAINING THAT KNOWS WHEN YOU'RE COOKED A workout log records what you did. GymHack reads what it's doing to you. NO ACCOUNT. EVER. Open the app and train. No email, no signup wall, no "create an account to continue." Your data lives on your device, backed up to your own iCloud. BUILT FOR YOUR GYM, NOT A GENERIC ONE Every gym is different. Yours has that one plate-loaded machine nobody else stocks, or a cable setup with its own quirks. GymHack lets you add your own exercises and your own machines — name them, photograph them, tell the app what they count as, and train with them like any built-in movement. And your AI Coach — a PRO feature, currently in beta — knows about them. Ask it to build a session around what your gym actually has, and it programs with your custom machines and exercises — not a stock library that pretends every gym is identical.

About

LOG1

Features
Read full description

Stop juggling 10 different apps to track your life. LOG1 is the one app that replaces them all. LOG1 is a universal life tracker that adapts to you — not the other way around. Whether you want to track workouts, daily habits, health metrics, reading, medication, weight, sleep, water intake, or anything else you can think of, LOG1 lets you build your own tracking system from scratch. Your trackers, your rules. Create custom activity types with exactly the parameters you need. Add numbers, durations, text notes, yes/no checkboxes, dropdown selections, or date fields — mix and match freely. Organize everything into color-coded categories for a clean overview. No predefined templates forcing you into someone else's workflow. Set goals that actually make sense. Define frequency goals (run 4 times a week), cumulative goals (read 500 pages this month), or target value goals (reach a body weight under 80 kg). Track both good habits you want to build and bad habits you want to reduce. LOG1 evaluates your progress automatically across daily, weekly, monthly, or yearly periods. See your progress at a glance. The dashboard gives you a complete picture of your week — goal completion, daily activity dots, and a contribution calendar that reveals your long-term patterns. Dive into detailed charts with line graphs, bar charts, and statistics including averages, min/max values, and trends over time. Built for privacy and simplicity. All your data is stored locally on your device. No account required to start tracking. No ads, no social features, no distractions — just a clean, focused tool that does one thing exceptionally well. Export your data anytime in a portable format. What makes LOG1 different? Most tracking apps lock you into a single domain — one app for fitness, another for habits, another for health. LOG1 takes a fundamentally different approach: you define what you want to track and how. The same powerful engine handles everything, from simple daily check-ins to detailed multi-parameter activity logs. Key features: Fully customizable trackers with 6 parameter types Flexible goal system with automatic progress evaluation Interactive dashboard with weekly overview and calendar Detailed charts and statistics for every metric Categories with custom colors and icons Offline-first — your data stays on your device Clean dark interface designed for daily use Localized in English and Slovak Start tracking your life — your way.
