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:
(Paid) BGG synchronization
Tons of stats and graphs with metrics such as win-rate
Nice interface
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.
Huh, I was not aware ScorePal was abandoned, I've been using it since 2017 and still use it regularly. Guess that's why the Google Drive backup is wonky now haha. Abandoned or no still a fantastic and functional app, maybe it's proof of the "if it ain't broke" philosophy
Edit: I'm seeing it was updated Feb 2022 to fix BGG syncing, are you sure you're using the original and not a clone? Or is it an iPhone thing maybe? I'm on Android
Trying signing out of BGG sync in the app settings, re-sign in and then 'refresh' your plays (swipe down when you are on the boardgames list page). This has fixed the issue for me in the past.
