Pick TimeTree if

You need a free, straightforward shared calendar primarily for scheduling appointments and events with family or friends, and you value cross-platform compatibility and ease of use R5R11R17R35. You are willing to tolerate ads in the free version or pay for a single premium subscription for an ad-free experience R1R6.

Pick Cozi Family Organizer if

You are looking for a more comprehensive family organizer that includes shared calendars, grocery lists, to-do lists, and meal planning, and you are prepared to pay for a premium subscription to access these features .

  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. [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!
  4. [R35] TimeTree 5/5 · US So convenient: My family loves this free family calendar. You can label events by color. You can get notifications when someone ads an event.
  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. [R20] TimeTree 5/5 · US Know Your Whereabouts!: Excellent app for time management
  8. [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
  9. [R9] TimeTree 3/5 · US Doesn’t work properly on Iphone: It works very slow on iphones
  10. [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
  11. [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
  12. [R30] TimeTree 3/5 · US Please consider changing this: I love this app dearly, it helps me stay organized like there’s no tomorrow. It works seamlessly and I’ve had it for over 5 years. With the latest update of having to have the IOS 17.0 or later update, I can no longer use this app and I’m extremely upset over it. I do not have the storage to update my phone therefore I cannot get the latest version of the app. There
  13. [R53] TimeTree 5/5 · US The best: I came across this app because I googled "best planning app for people with ADHD" and this is what google said to get. It's 100% true. It's helped me stay on track so much! I love the color coding and multiple calendar options. And being able to share calendars with other people.
  14. [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.
  15. [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.
  16. [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
  17. [R82] Cozi Family Organizer 1/5 · US No customer service: I’ve used this app since 2012, 14 years!!!! Has been amazing, but had an issue and the help link immediately sends you to a blank web site but won’t let you click the links within the help page on the app. I’ve been charged twice! $39. So if it doesn’t get resolved, they may have charged me $78, but it’ll be the end of our 14 year relationship and they won’t get any more refer
  18. [R92] Cozi Family Organizer 5/5 · US Great for families: Our teen is in charge of putting all her items on the Cozi calendar and it sends all of us a daily & weeks to keep us organized
  19. [R118] Cozi Family Organizer 1/5 · GB How can I contact for help?: Purchased this app for £39 which is the Gold version, can’t access gold features. In the setting it states account type free when I select upgrade it states I already have it? The shared password doesn’t work for family members, how can I get help as this is turning out to be a waste of money and time. No email address to get help
  20. [R67] Cozi Family Organizer 2/5 · US Lots of bugs lately: Items disappearing off lists, items checked off on one list but not checked off on the other person’s (all while on a good connection)
  21. [R79] Cozi Family Organizer 1/5 · US Deletes list items: The entire point of the app is shared lists, but sometimes it randomly deletes items after you add them. It also has a lot of ads and a clunky UX, but that would be okay if it worked to maintain shared lists. Unfortunately it doesn’t.
  22. [R85] Cozi Family Organizer 1/5 · US Recent Bug Makes It Unusable: My husband and I downloaded Cozi in 2021 and it’s been our go-to grocery app for years, but in the past couple of months it has stopped being useful, I will add something and it will vanish when my husband refreshes his list, or I will delete items that will reappear when he opens his. The solution has been for him to be the only one updating the list, which defeats
  23. [R96] Cozi Family Organizer 3/5 · US I used to love it: I used to love Cozi but lately it has been deleting the items from my lists after I added it. Specially after I add it from a recipe.
  24. [R16] TimeTree 2/5 · US No family plan: With this app being a shared calendar app it makes no sense that there isn't a family plan to remove ads/premium experience and it's $45 a year per person. That's wild work.
  25. [R66] Cozi Family Organizer 3/5 · US Kat: I love Cozi but the Cozi gold is pricey and could be a lower price.
  26. [R68] Cozi Family Organizer 4/5 · US $$: Great app but too much $$$
  27. [R69] Cozi Family Organizer 3/5 · US Love Cozi but...: We love Cozi! Have had Cozi Gold a few years and we use it so much but am really disappointed they won’t provide integration with Google Home or Siri nor automation APIs. Am using Google Assistant’s shopping list more these days and sadly may not renew my Cozi subscription since it lacks API integrations.
  28. [R84] Cozi Family Organizer 3/5 · US Excellent: Edit: we upgraded to the paid version for the additional features, but they don’t work. We can’t get the reminders or alerts to work, which is a particularly frustrating thing. As per the original review, we continue to have trouble with the app freezing on our phones. Cozy is awesome. Three adults and one child in our family all get where we need to be, which is amazing. The shoppin
