IOS – Collaborative spreadsheet application

I'm looking for an application that will allow me to create fields that represent 'points' to keep tally on mod actions by my online community. Another mod or user who i give permissions to can update the points while mods without permissions to update the points have read only access.
Once points are updated, the 'total' column is updated.
While you get 1 point for every mod action, some column should be worth more or have a higher multiplier than others.
I'm not even sure if a spreadsheet is strictly needed or if it can be something else.
I've tried google sheets but that seems clunky.
I was wondering if there was a mac specific or ios specific app i could use that wouldn't require the participants of the spreadsheet to have a mac to view it.
maybe something with bot an ios and android app.
