## ISO Today Reviews in United States

### ***-- "New text size"
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.
-- AStrand, 2024-11-06

### *---- "App does not work"
The app on my iPhone 11 Pro gives an Error message, and no information.
-- LZENYA314, 2024-05-17

### ****- "Very nice app"
The app has a lot of great informative information. The ability to get power network alerts is helpful for personal conservation to lower demand. The ability to get localized alerts would be helpful. Power problems in areas that do not have an effect locally is extraneous. Would be nice to be able to turn on/off alerts for specific locales.
-- P@b1ito, 2022-12-10

### ****- "Very good app"
This app has all the necessary information for the grid. Good job. There are a couple of problems one is that the alerts cannot be cleared. The other is that the page that displays the current state of the grid does not scroll properly when there are alerts on the grid status. I tried to refresh page or pull it but it is hard to use.
-- BRUCDG, 2022-09-08

### ***-- "Correctable errors, otherwise great"
Basically the general functions of the app seem excellent, with the alerts directly useful to consumers, the other data interesting and educational. 

Bugs: 
* On a smaller-screen iPhone (e.g., 6s) the items below Calendar on the Home Screen are difficult-to-impossible to reach. “Daily Briefing” is only half-visible, and can be tapped with care, but “Twitter” and “About Flex Alert” can only be seen while holding a swipe-up but cannot be tapped. * “Calendar” crashes instantly and reproducibly. 

Fix these bugs and my rating would be 4+. Otherwise it seems like a great app. I like the plotting options and all the informative “(i)”-button help screens. 

Feature request: 
* Add an ability to see multi-day and seasonal trends.

Support previous commenter’s request for a home-screen widget! Show the current alert status, maybe with time remaining before the alert ends, and perhaps the current demand.
-- gscrutiny, 2022-09-07

### ***** "Wow"
This app is unreasonably cool. Very easy to use, aesthetically pleasing, and full of interesting information. My only suggestion so far would be to include widgets so I can see some info at a glance on my Home Screen
-- bloudermilk, 2022-05-02

### ***** "The future of consumers understanding their electricity use"
I’ve been consuming CAISO’s online reports for sometime now and I’m quite pleased the app has my most often consumer reports easily displayed in the alongside a few new ones. I encourage them to continue their great work. This is the future of consumers understanding how their time of use can have a large impact on emissions, prices and stability of the grid. Keep it up!
-- Adhesive woman, 2021-10-07

### *---- "Crashes every time I try to launch it"
This app is useless. I just installed it and it crashes every single time I launch it :(
-- Pastafarious, 2021-06-18

### ****- "Calendar Crash"
1) Launch app version 4.3
2) Tap calendar

CRASH!
-- Davis P, 2021-06-16

### **--- "Alerts broken"
I don’t need three alerts for each restricted maintenance operations alert. None would be preferable.  I turned all alerts off and yet I’m still getting these. 

Have an alerting option for the general public. We want to know when we need to try and conserve more in real time. We don’t care about the restrictions on maintenance operations. 

Going to disable alerts for the app in OS now.
