My mission is to deliver a workout training log app that will help you make progress, build strength, and ensure hypertrophy, all that for free. I will never change the free feature to a paid one, spam the paywall, limit routines or workout logs, etc. (all the bad stuff other workout trackers do). What stands Strive apart: - Create unlimited workout routines, most trackers paywall this - Crate workout plans, assign workouts to days or in an order - Share your workouts with your friends or followers - train together without paying - Set weight or reps for the next workount and ensure progressive overload, go get those gains - RIR/RPE tracking with effective reps metric - Sync cardio and bodyweight with Health so you don't have to input the data manually - Mark workouts as deloads to better understand and analyze the data - Advanced charts without paywall, analyze routine, bodypart or exercise progress - Fully offline - I know some gyms have poor reception - Rest timer personalizeable per exercise - Personalizable dashboard - Choose from many widgets in various sizes to compose your dashboard, just like your phone's homescreen. Have all the data visible at a glance! - Placeholder exercise, select exercise category and bodypart or a group of exercises and then select the actual exercise when working out, based on the feelings or what's free at the gym - Custom keyboard to input workout data frictionlessly, allows to copy value from previous set, set value to all sets, and increment and decrement value - Wrapped, see your year in review at the end of the year - Themes & theme creator - Privacy first - no data tracking - No ads Rest of the features that you would expect: - Measurements and weight ins - Notes - Backup - never loos your data - Prs - Use all the set types, warmup, dropset, myo reps etc - Workout finish reminder - never again open an app to see that you have not saved the previous training - Dark mode - Exercise database I hope my app will help you achieve your goals, in general, just progress and get better. I promise to develop this app until it is your favorite gym log and workout tracker app. Remember, we all are gonna make it! Your gym bro, Artur. _________________________________________ Terms of Use: https://strive-workout.com/terms-conditions/ Privacy Policy: https://strive-workout.com/privacy-policy/
