I have used the Intensity app for years and it's got Stronglifts 5x5 and many others already programmed into it. Here's the Google Play download link.
old skool ... Staedtler mechanical pencil (2mm leads), a fancy multi lead mechanical pencil w/ various colors and A6 size notebook ... PRs get a star (i think those are the ones that matter!) the stars are transferred to symmetricstrength.
warmup yes. definitely working reps. T3s/assistance yes. i can easily scribble anything on the paper. general things like how i felt during/after the lifts (fatigued, still fresh, knee pain again, shoulder pain again). my weight taken after training session.
i used to transfer all my notes to Intensity on Android but i got bored doing that.
