An idea that would help my hobby and maybe other also would be a quick way of tracking and calculating the correct weights to lift for continuous and injury free progress.  I have currently made an excel spreadsheet that calculates my training weights based off 70% or 60% of my best lift.  This is the safe zone for lifting repeatedly safely.  This spreadsheet then calculates an additional 2.5% to add after each training session to ensure that progress is being made.  Once the lifter begins to struggle to complete a set or lifts (for example 8 repetitions) the spreadsheet will reduce it by 2.5%. 

This is a quick and easy way to track your progress and remove any confusion to what your normal (working) sets should be.  Perhaps a device secured to the lifter such as a smart watch could track their movement to count their repetitions and automatically update the program, making this even easier.  A camera could watch the lifter and count their lifts or assess the quality of their lifts by using machine/AI learning.  

I do not know of a program currently available that offers this service for weightlifters.  I have been using this excel spreadsheet for a while and I have had great success with it. I've attached a picture of the excel spreadsheet.
