  1. [R3] Saturn Calendar 3/5 · US Good app Please Add Crocus Plains,Vincent Massey And Neelin Highschools from brandon mb: Please add those schools
  2. [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!
  3. [R16] Saturn Calendar 1/5 · US .: I can’t find my school
  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. [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
  6. [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
  7. [R12] Saturn Calendar 3/5 · US Update: So i got the app, but i genuinely cant go into the app anymore because i don't have to the new phone version it wants me to update too.
  8. [R10] Saturn Calendar 2/5 · US Could be great but: For the life of me I can't get my Google calendar to show....it's connected to Saturn, it's synced, it just won't show up. I've trief removing it and adding it again; I've tried reinstalling the app....nothing.
  9. [R19] Saturn Calendar 2/5 · US Log out: A good app while you can still use it. It keeps randomly logging me out and it I try to log back in with snapchat and a phone number it tells me “Something went wrong please try again” everytime.
  10. [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
  11. [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
  12. [R13] Saturn Calendar 1/5 · US Saturn should be accessible for all: I was able to access Saturn before the “new update” occurred, and now I am unable to use it because it requires an update that only accommodates newer iPhones. Mine is an X and I can no longer use Saturn because it opens at a screen that says to update, with a button that leads to the app store, where it kindly informs me that I’m unable to update the app becau
  13. [R21] Saturn Calendar 3/5 · US More accessibility: It’s a great app, but i wish it was available to junior high. I am currently in eight grade, which is 13-14 years old (meets the age requirement for the app). But it sucks that we’re old enough for the app but there’s no option for our schools.
  14. [R35] Saturn Calendar 5/5 · US Love Love then my state banned phones: I used this everyday from freshman year to junior year until my state banned phones in school. I was so excited to input my senior class schedule and then boom no phones. Will miss you forever Saturn and definitely downloading again for college!
  15. [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
  16. [R28] Saturn Calendar 1/5 · US Horrible UI, zero support or help system, no way to manually input schedules: E
  17. [R61] Calendar · Planner & Reminders 2/5 · US Not Getting What I Paid For Again: I paid for the Pro version of this app, and I am experiencing for the third time this year not getting what I have paid for. When I use the contact link on the developer site, I continually get an error that my message cannot be sent. This app is fine if you don’t mind constant ads but be aware that you will get them even if you pay not to.
  18. [R2] Saturn Calendar 5/5 · US Class of 2030: Nice app! I just want class of 2030 to be added
  19. [R5] Saturn Calendar 5/5 · US ADD CLASS OF 2030!!: can u please add class of 2030? we are freshman now😭
  20. [R63] Calendar · Planner & Reminders 3/5 · US Good but…: I love this app but it constantly makes me “restore” my subscription. Which is not a be deal in theory, but when you have to pull up your calendar fast but then have watch a one minute ad (when you pay 5 dollars a month), it’s not ideal… please fix this problem!! I might have to look for another calendar app if it’s not resolved.
  21. [R67] Calendar · Planner & Reminders 1/5 · US Ads?: Why do I get ads? I pay for subscription
  22. [R70] Calendar · Planner & Reminders 2/5 · US Pop ups?: Not sure why you get a pop up every time you open the calendar? I payed for the premium subscription and still get pop ups? Very disappointing
  23. [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
