Please fix this ### 4/5 — Well made *2024-06-01, version 2.10.3* This app is very well made and simple to use however, i have one suggestion. You let us add our grade level so would you be able to make the calendar show grade specific activities as well? For example, I'm a senior and the last week shows finals but we dont have finals we have senior activities. It would be nice to know the times for those things instead. ### 4/5 — any apps? *2021-11-02, version 2.0.4* is there a app for Woodbridge highschool ? ### 4/5 — Very useful for high schoolers in Irvine *2020-08-20, version 1.1.1* Great app but each time I close the app and open it all my classes in the edit classes section disappear ### 5/5 — Good app! (+suggestions) *2019-09-26, version 0.9.3* I love this app! It looks very clean and easy to use. However, can you add a “teachers” function like in Portolapp to get emails and names of teachers? ### 3/5 — ADD COMPATIBILITY WITH OTHER SCHOOLS *2019-09-25, version 0.9.2* This app is an amazing concept but I would really want to be able to use it from another school rather than just the Irvine School District. Please make this happen. ### 5/5 — wow!—& a few suggestions *2019-09-20, version 0.9.1* first of all, WOW! i am so proud of the development team! you guys are doing awesome! i am IN LOVE with the dark theme! a few suggestions: 1. on dark mode, the part of the circle that isn’t filled in is too similar to the background color. it’s hard to see. 2. it would be cool if you could add a picture to your ID card (if you wanted; you shouldn’t have to). 3. please add a search function in the sports section. an idea: maybe make it so you can “favorite” a sport, so it’s always on top when you open it. 4. because the school week starts on monday, so should the calendar. having the weekend split across the calendar is confusing. 5. in Portolapp, if you added your classes, it would show as “[class] ends in 28 minutes...” do you plan on adding this feature back? GREAT WORK!! ### 5/5 — Great!!!!! *2019-09-20, version 0.9.1* This app is really cool and great because it tells me more things and it is more organized. I really love the dark theme as well and how this app helps me with what is going throughout the school year. ## Most critical reviews (10 lowest-rated) ### 1/5 — FIX THIS *2025-08-18, version 3.5.2* IM TRYING TO LOG IN BACK BECAUSE IT KICK ME OUT FOR SOME Reason AND ITS ASKING ME TO PUT MY LAST NAME AND MY STUDENT ID AND MY BIRTHDAY. I DID ALL OF THEM THAN IT DOESN’T LET ME IN IT KEEPS SAYING ITS WRONG BUT IM Putting EVERYTHING RIGHT 😭💀🙏 ### 1/5 — Terrorism *2025-07-21* This is terrorism ### 1/5 — Doesn’t work on my iPhone *2024-12-09* Other users have the same problem, the app won’t open or load on an iPhone 16 ### 1/5 — Inefficient *2024-10-28, version 3.0.7* Say, can you see By the dawn's early light What so proudly we hailed At the twilight's last gleaming? Whose broad stripes and bright stars Through the perilous fight O'er the ramparts we watched Were so gallantly, yeah, streaming? And the rockets' red glare The bombs bursting in air Gave proof through the night That our flag was still there O say, does that star-spangled banner yet wave O'er the land of the free and the home of the brave Ps, dosent work with iphone 16 and up ### 1/5 — no portola high school *2024-08-13, version 2.10.3* there is no portola high option ### 1/5 — Dosent let me be Kevin James *2023-08-29, version 2.9.5* Bad app ### 1/5 — Error *2023-08-01, version 2.2.1* I downloaded the app and can’t search for my school. I get “an error occurred”. I’ve tried deleting and reinstalling with no luck. Any suggestions? ### 2/5 — Not working *2024-12-04, version 3.0.8* The app hasn’t been working recently and won’t open/load ### 2/5 — Support iPhone 16 pro *2024-11-13* The app doesn’t work on my phone ### 2/5 — “An error occurred” *2023-08-11, version 2.2.1* I downloaded the app but when I tried searching for my school it just said “an error occurred” so how do I fix this? ## Most praised reviews (10 highest-rated) ### 5/5 — Perfect *2025-11-18, version 3.5.5* Very well made,friendly user for both students and parents ### 5/5 — can’t live without it! *2024-12-09, version 3.0.9* this app has so many helpful things for day-to-day life at school. being able to quickly check the amount of time left in class saves countless time and mental energy that can be used to focus on what still needs to get done in the period. the calendar is really helpful to to see what types of days/weeks/events are coming up!! ### 5/5 — Not working *2024-12-05, version 3.0.8* This app is great. But there seems to be a problem. It is not going past the initial page. ### 5/5 — It works *2024-10-23, version 3.0.6* The app works. I get announcements from my club which is nice ### 5/5 — Ig:223.antwon *2023-08-17* Follow me 😹 ### 5/5 — Very Useful App *2022-09-01, version 2.2.0* This year, my school began using this app and almost all the students and staff use it. It’s very helpful! It tells you when your next class is, what events are coming up, what sports and clubs are available, and so much more. You can also personalize your ID, which is a pretty neat feature. However, I do have a suggestion: student users should be able to make their own private events that show up on their Integral calendar page (if that’s already a feature and I’m just too dumb to see it, I apologize). Overall, I absolutely love this app and I’m glad that my school decided to implement it. I’d definitely recommend this to others! ### 5/5 — So good *2021-08-20, version 2.0.3* So good. Very well made. Easy setup. Hi Patrick ### 5/5 — Very nice *2019-11-19, version 1.0.4* Super useful. ### 5/5 — RIP Portolapp *2019-09-27, version 0.9.3* They still couldn’t find a better name. ### 5/5 — Awesome! *2019-09-27, version 0.9.3* Keep up the great work! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
