For the longest time I've been using ScorePal. This app is amazing.
The best functionality is that it has "score sheet templates". These templates that are created by community and can then be used by everyone freely. All you had to do was select the game and fill the score sheet, the app calculates score and winners automatically. Here's a pic from their website
The app also has other goodies such as:
Unfortunately this app is no longer mantained by the original creator, last update is from 2018. BGG synchronization seems broken, I never find community score sheet templates anymore. I can still create my own scoring templates, it works fine, but the community aspect is gone.
I was wondering what everyone else is using. I've tried a bunch of apps, but I never found an app that is so good at creating custom scoring templates as ScorePal. I'd like to support an active developer but haven't found a good alternative.
I’m a big fan of Board Game Stats and it is regularly updated, last time being a month ago.
