5 stars: There's not really a lot to say about the industry standard. Kinda like saying
4 stars: It's not bad for an app based spreadsheet. I use it for tracking my workouts so it's a pretty basic use. It did upload well from my original sheet and I can download it into my PC Excel to extract data, so that's good utility. Navigation is a bit difficult on a small phone touch screen. I dont know if it would be of much use with a more complicated spreadsheet but I haven'ttried that. So, ya, it's ok.
4 stars: I've used Excel for many years on desktop computers and found it very powerful. Using Excel on my smartphone is not as easy. This is also a newer version so there are some differences. I will probably discover some nice improvements. I've just created a swim log tailored to my interests with my desktop and transferred it to my phone where it will be conveniently available.
3 stars: I've been using excel mobile for years, and after the recent update noticed that I can no longer freeze panes. I primarily use it to track my workouts, and not being able to freeze the column with my workouts in it as the weeks go by is extremely tedious and frustrating, especially since I was able to do that for so long, and now it's just gone.
3 stars: Problems syncing with my one drive. All my changes have been made on my phone yet when I try logging back into the file it says it can't download the changed version because another user has made the changes. It was definitely me ...
