  1. [R11] Saturn Calendar 4/5 · US Cutie Patootie!: Super cute app for when i started high school! Though, when I pressed a button to “invite” someone to the app, it sent them like a text of my schedule which i didn’t expect, but it lowkey makes sense so that’s nothing to bad lol. Thanks for this app, it’s very nice and knows ur schedule very well!
  2. [R53] Saturn Calendar 5/5 · US Pretty good :D: I like that it keeps track of my classes, and is incredibly accurate as well as keeping me connected with people who are in the same classes however it has problems AT LEAST once a day. Sometimes in the middle of the day it’ll switch over to the “no school” schedule for no reason, often has bugs where the window that shows you how much you have left in a class shows up twice, and s
  3. [R59] Saturn Calendar 5/5 · US Extremely useful: As someone currently in High School Junior year this is a life saver
  4. [R22] Saturn Calendar 1/5 · US AI feature is useless: It used to be a good scheduling app before you depended on an extremely buggy AI system for scheduling. I’d much rather manually put my classes in, because everytime i put a photo of my ACTUAL school schedule, it asks for a school-wide(???) schedule instead. Deleting.
  5. [R56] Saturn Calendar 5/5 · US Saturn: I love the app very help full for my classes
  6. [R15] Saturn Calendar 3/5 · US uh: so saturn is really fun when you actually get your profile activated! they don’t let you get the profile activated with ai but they need humans to check in, but they take 2-3 days to even see you. i found it infuriating because my app kept glitching and logging me out and then by the time my account was activated i had to delete my account 5 times…. would not recommend
  7. [R6] Saturn Calendar 3/5 · US Terrible update: saturn was working just fine until a few months ago it had an update and it asks my phone number for a verification code there is no code whatsoever please fix igttg
  8. [R23] Saturn Calendar 4/5 · US Error in calendar: The calendar is very simple while also being very useful for my school, but for some reason around every 2 months, all my classes disappear and tell me that I need to set my schedule again. So I constantly call support (which is probably almost just as good as steam support) to get my schedule back the way it was. Overall , the Saturn calendar is amazing, but I would like the sc
  9. [R36] Saturn Calendar 3/5 · US Problems: While this app helps me see what time my classes are and how long, it has done it multiple times were it “forgets my schedule” and leaves me without a schedule for some reason while when I try to choose what schedule i need it gives me the wrong one
  10. [R55] Saturn Calendar 2/5 · US Missing Schedules: Almost every other week my schedule is missing in Saturn and it takes multiple day for it to pop up also it’s so difficult to change your schedule
  11. [R9] Saturn Calendar 3/5 · US Regarding an issue with the class schedules: I just want to say that days when I have classes will say it is a free day or no school. This is totally incorrect and when I try changing the schedule, it just stays loading saying it is “finishing things up” or “finalizing your schedule” making me stuck with the stupid alien. (Y’all know what I’m talking about) I just ask that you take a look into thi
  12. [R31] Saturn Calendar 1/5 · US Not as advertised: Advertised as a ADHD calendar, you are forced to enter a school before using, asking only after putting in all your information. Potentially a data farm.
  13. [R40] Saturn Calendar 1/5 · US Glitchy: This app is so incredibly glitchy, first whenever I tried to put my schedule in it would not add my glasses, no matter how many times I tried, so I had to manually add them only for the app to change the days so that the classes show up on the wrong day and it always goes back no matter how many times I fix it. I just deleted it.
  14. [R52] Saturn Calendar 1/5 · US Awful: terrible schedule management and doesn’t display accurate classes. need to manually insert classes which takes out a large chunk of time.
  15. [R67] Countdown 1/5 · US Pay: Have to pay for widgets on screen
  16. [R28] Saturn Calendar 1/5 · US Horrible UI, zero support or help system, no way to manually input schedules: E
  17. [R43] Saturn Calendar 1/5 · US Couldn’t even use it: I’ve tried every possible way to get into Saturn using my phone number and every single time it has not messaged my number. Can yall fix that please😭
  18. [R1] Saturn Calendar 1/5 · US No new years: I am trying to login to see who is in my class next year but they don’t have the 2030 option so i can’t login could be a better app if they were on top of things
  19. [R2] Saturn Calendar 5/5 · US Class of 2030: Nice app! I just want class of 2030 to be added
  20. [R3] Saturn Calendar 3/5 · US Good app Please Add Crocus Plains,Vincent Massey And Neelin Highschools from brandon mb: Please add those schools
  21. [R5] Saturn Calendar 5/5 · US ADD CLASS OF 2030!!: can u please add class of 2030? we are freshman now😭
  22. [R68] Countdown 4/5 · US Amazing: It countdowns well and is very useful for keeping track of things, but it's a little overexessive to make people pay to set it as a widget
  23. [R69] Countdown 3/5 · US Deleted same day as downloaded: I downloaded this app because I wanted something to visually track the days left until certain events. Problem was that the widget only shows that there are countdowns. I have to open to app to see how many days are left. That defeated the purpose of being able to use the app to visualize the countdown. I could pay to have widgets that show the countdown. But I don’
  24. [R70] Countdown 1/5 · US Have to pay to use widget: Why would I get a countdown I can’t even see. The cost of this app is absurd.
  25. [R61] Countdown 1/5 · US Trash stop spamming ads every time someone opens your app: Trash stop spamming ads every time someone opens your app
  26. [R72] Countdown 3/5 · US Too many ads: Too many advertisements for an app that only calculates how many years, months and days you have left until your event. You have to pay for premium to stop the ads.
  27. [R73] Countdown 1/5 · US Ads Ads and more ADS: How many ads can a single app have? Not enough, according to the developers of this app.
  28. [R75] Countdown 3/5 · US Great app: Helps me keep track of important dates!! I love the feature where you can see exactly the seconds, minutes, hours, and so on. The reason it lost 2 stars, lots of ads.
