Last year I was in a fantasy gambling league with some friends where the commissioner took screenshots of a sportsbook app, and told us to send us picks from different categories, each pick was worth a point and we would tally them all up in a spreadsheet and then the winner each week would win a prize and there were prizes for the end of the season. This got me thinking there had to be a better way to do this, so I started working on Pick'em.
At first it was just a script that build a google sheet manually each week from real odds. That turned into another script to grade that sheet, then I embedded the sheets into a google site and thought how much farther could I push it. Over a 1000 hours later, a lot of nights and weekends and Pick'em the app was born.
It uses real odds, grades in close to real time, has achievements, public leagues, chat, custom leagues rules, push notifications, stats, and more. I am really proud of it, and for now I just want people to check it out especially with NBA starting tonight its a great time to get in and check it out, or pop into a public league for a week. I also have a free demo that you do not need to create an account for if you just want to see how it works.
The part of the site that I think would be of intresting to r/gambling is I have a betting trends section on my website that builds over the course of the season that shows gambling stats trends for every team and has a breakdown to help you make better picks https://pickem.fan/betting-trends/ . That is free, no sign up or log in needed and I do not have any adds on the site right now, this is a new thing I am doing for the love of the game!
Just wanted to share my project, hope it will be helpful to some folks here
