  1. [R5] TimeTree 5/5 · US I love it: Me an my significant other have been looking for a calendar to share and this works great for us !
  2. [R11] TimeTree 5/5 · US Wife-hub: I love this app very convenient and always recommend to my couples friends! I have Apple and hubs has android and this is so great for me keeping track of everything with our toddler and families. Allows him to see and edit also! You can add notes or locations for events and I’m a visual person so I color code certain things like Dr apt.
  3. [R23] TimeTree 5/5 · US This app has changed my life: I have crippling ADHD and have always struggled with keeping a calendar/planner. Being able to add friends and family to my calendar really helps with accountability and helps with me not double booking myself. I am the only one in my circle that really uses the app. Even though I am the only one adding to my shared schedule, this app is still amazing.
  4. [R29] TimeTree 5/5 · US Glen Bliss: This is a wonderful shared calendar system which is perfect for family and small business appointments. 5 stars!
  5. [R6] TimeTree 3/5 · US Great Calendar for Fam, Obnoxious ads…: Pros: Great planner for keeping up to date with family. Convenient and easy to use. Easy to navigate and set up. Cons: Too many ads, many large and invasive. Ads take up 1/3 the screen. Gambling and casino ads. :( Recommendation: Make small banner ads at the bottom. Ads make the app look low quality and shady.
  6. [R8] TimeTree 5/5 · US Wonderful: Great place for all the important stuff, easy to use and free!!
  7. [R10] TimeTree 1/5 · US Not enjoying the premium experience: It is very difficult to move from week to day view. You are unable to click on a day to make it expand or using a pinch motion function on the screen to zoom in and out. Most of the functions feel hidden, like importing external calendar info, which must be done every time I update my external calendar. The support function doesn’t work without images and there
  8. [R15] TimeTree 3/5 · US Extra steps: Adding the extra steps to get to the memos/notes section is annoying
  9. [R3] TimeTree 3/5 · US Good product: Overall good product. It’s only screwed me one time when I put in a doctors appointment for 8:30 AM and when it was saved and you go out of the appointment, it showed 9:30 AM could not fix that event. Had to delete it and redo it but I didn’t notice that until after I missed my appointment.
  10. [R9] TimeTree 3/5 · US Doesn’t work properly on Iphone: It works very slow on iphones
  11. [R12] TimeTree 3/5 · US Glirch or something: I had used this app for probably about 5 years. had all my plans and work schedule in it. and it deleted everything. I dont even understand how that is possible. but everything is gone and im very angry and frustrated. It was a good app but I guess like any app don't become reliable on it because it can fail you at any moment. I hadn't been on a guest account either, I was lo
  12. [R28] TimeTree 2/5 · US I did love this app: In the last month it’s started glitching on me like crazy. It’s bad enough you’re trying to making people pay a premium mode for a damn calendar but now you’re messing the code up and I can’t see my events. I’m ready to leave
  13. [R1] TimeTree 1/5 · US 100% NOT worth it: Why can’t I export this calendar to something like Google Calendar?? I’m forced to use this one now. The ads at the top make the overall calendar hideous. Money hungry app that forces you to pay if you don’t want to see ads. Please just use Google calendar or Apple calendar.
  14. [R4] TimeTree 2/5 · US ads: too many ads, very annoying. other than that works well.
  15. [R7] TimeTree 1/5 · US Used to be good: Greed has completely overtaken TimeTree. It used to be a good shared calendar with non invasive ads. Now they have pop ups take up the entire screen that you have to X out. Find a different calendar. I know I am now.
  16. [R26] TimeTree 5/5 · US Functional & Super Cute!!: I seriously love this calendar. i’ve been using it since november of 2024 and i haven’t used another one since then. it’s simple to use, you can have up to 3 separate calendars, and you can rename certain colors! if you put your work schedule in, you can name the color “work” or whatever you want. the only complaint that i think i have would probably be the fact that i w
  17. [R25] TimeTree 1/5 · US Lack of Export Ability: It’s a fine calendar for keeping up with family events and the color system does help. The reason I gave it one star is because it does not have the ability to export into my work calendar. I’m having to switch back-and-forth between calendars to determine if I can take a meeting or not. Fix this and it would be a good app.
  18. [R17] TimeTree 5/5 · US Perfect for personal and communal use.: I got this app in hopes of sharing my schedule with my girlfriend and keeping track of it myself. It is a godsend. There is no paywall so everything is accessible for free except non-essential decorations. I can see and interact with anyone on my calendar and add a multitude of useful information and visual. Best calendar app I’ve used.
  19. [R81] 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.
  20. [R89] Saturn Calendar 4/5 · US School: I wish that this app would have middle school it because i am in middle school can you make this a new feature?
  21. [R63] Saturn Calendar 3/5 · US Good app Please Add Crocus Plains,Vincent Massey And Neelin Highschools from brandon mb: Please add those schools
  22. [R76] Saturn Calendar 1/5 · US .: I can’t find my school
  23. [R109] Saturn Calendar 2/5 · US Where is my school?: My school is there, it's in this app, but for some reason I can't access it.
