LiftLog is a strength training tracking app designed to help you get stronger simply by recording. It meticulously records your workouts, visualizes the data, and the AI ​​helps you plan your next routine. It transforms intuitive training into evidence-based steps.

■ Main Features

▶ Consult with AI during training: "Should I increase the weight next?"—Ask the AI ​​instantly. The AI's suggestions are reflected in your set with a single tap. Move forward to the next set with confidence, not hesitation.

▶ Workout recording in seconds: Your previous record is automatically displayed, so simply review and confirm. You can quickly resume with "Start with the same content," and easily record warm-up/main workout distinctions and RPE (Rating of Percentage Exertion).

▶ Rest Timer That Never Stops in the Background: Even when you close the app, the remaining time continues to tick in the lock screen notification. Automatically starts upon set completion, and you can adjust it by adding 30 seconds or skipping from the notification, ensuring you never miss an interval.

▶ Celebrate Your Personal Best (PR) Instantly: A celebratory animation plays when you set a new record. The feeling of surpassing your past self motivates you to take the next step.

▶ Visualize Your Growth with Data: View your 1RM and volume trends in graphs. See your total weekly volume and the balance of sets per muscle group at a glance, revealing which muscles are working and which are lacking.

▶ Weekly Goal Ring for Habit Formation: The ring displays your progress for the week. Consecutive weeks of achievement, comparisons with the previous week, and weekend review notifications help you stay motivated.

▶ Plate Calculator: Simply enter your target weight, and the app automatically calculates the plate combinations needed for the bar. Eliminates calculation errors and confusion at the gym.


▶ Manage your fitness with numbers: In addition to weight and body fat percentage, record and graph body part measurements (6 types of circumference). Automatically calculate nutritional goals based on your basal metabolic rate (BMR/TDEE) and display your achievement rate. (Weight, body fat percentage, and nutrition data are linked with Health Connect.)

▶ Share your results: Summarize your workout results in a single image card and share it on social media.

▶ Home screen widget & shortcuts: Check your weekly progress anytime with the home screen widget. Start your workout instantly with the shortcut (long-press the icon).
