Hi Samuel - I coach u10 team (for context) - I use a PowerPoint slide as a template for my session plans that states the objective / timings / things I need / things players need - lists the progressions and also aligns to the 4 corners. 
the language is very simple / jargon free so the players can understand it.  I then save as a pdf and send out via WhatsApp - parents and players alike love it.  We then use it as a reference point at the beginning of the session and review at the end to make sure we have progressed against the objective. Then we set ourselves a target for the game the next day - as an example this week we focussed on creating chances for longer range shots in training and then set a goal of 3 long range shots / quarter in the match the next day.  Parents are encouraged to celebrate the shots - if they score that’s a bonus!! 
There are lots of different applications ... but you can keep it simple too depending on what you want to achieve and how much time you have!!
