User Reviews

ISO Today provides rich CAISO grid data, useful alerts, and polished visuals, with recent updates expanding data and organization. Recurrent issues include crashes, slow loading, noisy/unclear alerts, and limited localization, plus calendar-related instability that affect usability.

Pros

Comprehensive, data-rich CAISO grid information.
Useful alerts for conservation and staying informed about grid conditions.
Clear, visually appealing data visualizations and plotting options.
Easy to use and aesthetically pleasing interface.
Recent updates add more data and improve organization.

Cons

Alerts are duplicated and hard to clear, leading to notification spam.
The app crashes frequently (crashes on launch and during use).
Performance can be slow, with long load/refresh times.
Alerts are not localized to the user’s area and lack granular filtering.
Calendar-related features crash or behave unreliably on some devices.

Super informative app. But would really make for a great (and simple) chart, is when you select the “% Renewables Serving Demand” on the home screen, the x-axis for the chart would be 0-100%, and the y-axis would be the time 0000-2400. This would be so you could see the peak time of renewables during the day, AND perhaps a calendar view where you can slide left and right from calendar month to month, in full calendar view, and it would show the highest percentage of renewables for that given calendar day. Then you can select the day you want to look at the full 0000-2400 chart. Kinda sorta like the Duo Lingo calendar, but it shows the highest score (%) on each day. It’s a bit tedious to find the day I want to observe when it’s always a full 24hr chart. Otherwise keep it up!

On my iPhone 12 with current is the text size for things like alerts is way too small. Changing the IOS text size for this app doesn't change the size. Bummer, I really like the app but this makes it hard to use.
