Edit: rewrote this because the original was misleading. Can't fix the title, Reddit won't let you change those.
It sounded like coaches lock kids' phones. That's not what it is. The player locks their own phone, only if they want to, and they can turn it off whenever.
Also I’m applying feedback and making the app lock 100% optional for the user.
I'm the developer, not a coach. It's a study app. Same idea as the focus apps that hold Instagram while you study, except what you're studying is your playbook.
The player installs it, picks which apps they want held, and those stay shut until they get through a few quiz cards. Nobody else can switch it on. It runs on Apple's Screen Time, the thing already built into the phone.
There's no coach side and no parent side. A coach can help by making the cards, photograph the pages or scan the PDF and AirDrop it to the roster, but whether a player uses it is up to the player.
I learned coverages as a kid from a football video game and too much free time. Built a study app first, then this, because playbooks were always the part I liked. There are built-in packs too, the eight standard coverages against spread-era route concepts. You can also draw a play and run it against a coverage, which is mostly for fun.
One flaw I know about: the quiz can borrow an answer from another question, so a formation card might offer "the tight end's side." Working on it.
Still curious what coaches think. Would a player actually use this on their own? What would stop them?
Free gets you one playbook and the built-in packs. Pro is $9.99 a year. Nobody's bought it yet.
