  1. [R2] Todoist 5/5 · US Amazing Application: I have been using this application for over 13 years and have been witness to the amazing product development that the task manager is today. Very intuitive data input allowing for simple daily reminders to complex team project management. I love the simplicity of quick task entry putting the essential organizing categories up front. It even allows for verbal entry. Ther
  2. [R8] Todoist 5/5 · US Great app: I love how flexible it is with when to plan things. Easy to figure out and keeps me on track.
  3. [R16] Todoist 2/5 · US Hmmmm: Wow, I must be a complete Moron, because I find this app to be very confusing! Deep Work? Weekly Reviews? 81 items to read in Deep Work alone! What’s up with all that? I just want a nice easy, clean “To do list” lol…..this app is WAY to complicated for imbeciles like me I guess.lol I’m sticking with Apple Notes & Reminders.
  4. [R33] Todoist 3/5 · GB such a good app: improvements: - option to enable a status ( to do, waiting, started, done) option instead of traditional check box. with customisable options - FIX IOS WIDGETS!! so annoying apart from these, amazing app haha
  5. [R3] Todoist 3/5 · US Calendar is the one big disappointment: I’m confused why I can’t sync my iCloud or a CalDav calendar with Todoist. I was hoping to move away from Google Calendar so it sucks that the options are so limited. I considered creating my own Todoist integration, but I don’t think the SDK allows me to sync calendar events. Looking for an app that can handle tasks and events with my family. The tasks par
  6. [R9] Todoist 3/5 · US Why??: This company is too successful to not be able to have direct calendar integration! Why? Calendar and to dos are too integrated to not include in a task manger.
  7. [R19] Todoist 1/5 · US Doesn’t connect to apple calender: Can’t use it for anything, doesn’t even connect to my calender? Built for iOS? Useless app.
  8. [R22] Todoist 1/5 · US No Apple Calendar Integration: No Apple Calendar integration in 2026 is insane. You won’t be able to add your calendar events to Todoist unless you use Google Calendar or Outlook. There are a lot of people that don’t want Google or Microsoft to have access to their personal calendar. Unfortunately, Todoist doesn’t care about those people.
  9. [R6] Todoist 3/5 · US bring back the add button: every since you guys removed the add button from the main menu i have been furious. my live is falling apart now please do add it back otherwise i will sue you.
  10. [R7] Todoist 1/5 · US Horrible Interface: This apps SUCKS. It’s impossible to add members, I literally only wanted to add one member to a project and it failed over 20 times. The interface sucks. Instead of it being easy to use and track, the setup itself was a nightmare to navigate and the page so messy with the multiple video and to do idea options
  11. [R1] Todoist 2/5 · US User: I was enjoying it but with software updates it tells me to download the latest version but will not allow it (I guess the new version can’t be run on older platforms). So, it still asks me to download the new version each time I open it, and it now no longer syncs between devices. And, as far as I can tell, there is NO WAY to contact customer support or get any help with it. A useful tool wh
  12. [R4] Todoist 1/5 · US No hay sincronización: Existe un falta de sincronización entre completar una tarea desde las notificaciones y creando tareas con Siri que no aparecen y no envía recordatorios a menos que necesariamente vuelva a abrir la aplicación
  13. [R5] Todoist 5/5 · US Big fan of this program: I’ve been using Todoist for years. It’s rock solid and I rely on it it to keep my life organized. Very good product.
  14. [R10] Todoist 1/5 · US Delays in updating the data and data loss: You change it on iPhone app, it can’t sync, overrides by desktop version, you lose your updated data. Ongoing problem for years.
  15. [R12] Todoist 3/5 · US Notes app is better: It’s like a step more advanced than the Apple Notes app in that it splits up tasks by days. But in my opinion, advanced doesn’t always mean better. Just less user-friendly in this case. Very simple app, 3 stars because it doesn’t make you pay for basic features. But I’m not a fan.
  16. [R17] Todoist 5/5 · US Well that was fast: Needed something fast. Downloaded fast. Up and running fast. Organized fast. Getting task done faster than ever! Free And Saving Time!
  17. [R27] Todoist 3/5 · GB Expect Spam: Downloaded this app, looks great and has great functionality, but I thought the in app purchases were quite expensive. The set up process includes giving your email and since deleting the app they haven’t stopped emailing me. I know businesses have to market their products but this is bordering on harassment
  18. [R31] Todoist 1/5 · US Useless Trash - & Privacy Concern!: Privacy concern because they have access to your data and there’s no opt out! Every platform I’ve used has an opt out except this one. Also - the app is useless. I didn’t increase my productivity in any way using this app. They keep sending annoying emails and spam notifications daily and trying to get you to upgrade. Also the interface is horrible and totally u
  19. [R28] Todoist 1/5 · US Support not responding: I’ve been a paid subscriber for over 8+ years. Lost access a week ago. Restore doesn’t work. Support not responding. Already submitted two tickets 7+ days ago.
  20. [R36] Todoist 3/5 · GB Delete all records: I'm very disappointed that while I joined in February on my results before mid June been deleted or inaccessible and todoist support couldn't help.
  21. [R42] Todoist 3/5 · GB Account verification flaky: Signed up on a monthly basis, and entered my projects. Started getting accounts verification requests in the app. Asked for email to be sent and tried to verify but it wouldn’t accept it. Subsequently no more emails have reached me. So I asked for help which raised a ticket but no follow up help. Trying to check the ticket says access denied. Warnings received that ac
  22. [R64] Calendars 1/5 · US Not the best: I have used many calendar apps and you have to pay for repeat events like wth!! Over rated in my opinion. Use time tree!
  23. [R66] Calendars 3/5 · US Don’t bother if looking for free: Can’t even have weekly events repeat without buying Pro. Thanks but no thanks.
  24. [R67] Calendars 2/5 · US Free version does not allow recurring events: Looking for free basic cal but lack of ability to make events recurring makes this an incomplete calendar. Other functions seemed great.
  25. [R78] Calendars 3/5 · US repeat: Its’s annoying that I have to pay for pro to repeat an event. I don’t want to have schedule work every single day when it’s the same time. Only spent like 5 minutes on the app but no point in getting it.
  26. [R55] Todoist 1/5 · US Customer Service is Nonexistent: I recently purchased and annual subscription to Todoist but unfortunately the app doesn't appear to recognize that I did. I submitted a support ticket (actually several) since there is no way you can actually speak to a human and they have yet to address this concern.
