Latest reviews

  • (2022-09-20) Vipika Kotangale: Keeps me organized everytime. Thanks for this wonderful extension. Loved it.
  • (2022-09-14) Олексій Гулієнко: Пречудове розширення! Автору подяка! Якщо можливо додайте українську мову. Рекомендую всім.
  • (2022-09-08) Web Rascals: We hate to leave a negative review because this extension did everything we needed it to...until we paid for it. Then it stopped working almost completely. We had to refresh and reboot multiple times a day. We missed several appointments (because we were relying on this extension), which was inconvenient and embarrassing. Again, it worked great, and did everything we needed from it, until we paid. If this extension is working for you, DON'T PAY for it, that might ruin a good thing. We hope the developer will find a way to fix the glitches keeping the extension from stalling out because we haven't found a better solution out there than this one (when it works).
  • (2022-09-07) JoAnn McKenna: Initially I was looking for something that I could have as an app on my desktop so that I could have one less webpage open. I found this and really like it. I still have to keep a page open but the cal layout is easier for me to view and stay on track for my workday. Thanks!
  • (2022-08-24) Ahmed Seoudi: The extension is great and it works except for one problem. After I dismiss the notifications they appear again accumulated with the newer notifications at a time I'ven't set for them!
  • (2022-07-25) Ned Peglar: perfect i love it so much!! I donate monthly to Jason for his awesome work.
  • (2022-07-21) Beanie “kamapa333” Palmer: I'm just an American girl, sharing my honest feedback! The calendar is ok, not great. Work on the bells and whistles, acknowledge those who sent donations and do not badger them for more cash. I was harsh but everyone is not perfect, and you need to feed your paying customers with new features and no 50 cents here and there. I am not a rich american, but realize your development of apps handy for my needs, you should be given appreciation. Thank you Jason for your code, your creation, the checker calendar. Peace, and love, as we unite within our hearts!
  • (2022-07-12) Alexandru-Claudius Virtopeanu: freemium. asks for money to do certain things such as dark mode.
  • (2022-06-25) Tripp Davis: This is an extremely well-written extension, and it's the only extension I've ever actually paid for.
  • (2022-06-03) Oleg: Please add the Ukrainian language
  • (2022-06-02) Jacquie Stoyek: I'm finding that it does not refresh / update / sync with my calendar and it gets "stuck" at indicating that my next meeting is in 4 mins or 13 mins, when in fact it's in an hour+
  • (2022-05-09) Dark Marce: Este programa si lo usas de manera gratuito no sirve, unicamente pagando todos los meses o pago unico.
  • (2022-04-30) Luniul: Перестало работать. Возможно дело в политике? Но это не красит разработчика. Будем искать альтернативу.
  • (2022-04-21) Антон Буйнов: Расширение просто ТОП. Так удобно я с календарем еще не работал. Те кто ставят маленькую оценку за платный функционал идиоты, донат для разработчика маленький, разве сложно поблагодарить ? Вы же не работаете бесплатно на работе.
  • (2022-04-17) Teddy DaBear: It seems okay. But I immediately came across a bug within the first 5 minutes of use. When I want to copy and paste information from another browser tab, the name of my MD from a medical portal, then the address, when I switch tabs and came back, the extension closed. So I couldn't do multiple cut and paste like Dr. Name, Address, and calendar comments because each time I switch tabs, the app would disappear. So far, it just make more sense to add a bookmark to google calendar on my bookmark bar.
  • (2022-03-27) Mohammed Umairuddin: Awesome work! ♥ 👍 If possible, can you add this feature: please add alternative calendar i have it in my goggle calendar pls add it it will be very helpful thank you
  • (2022-03-26) Reza Kasnavi: Awesome! my new favorite extension. thank you
  • (2022-03-24) Miriam Guichon: Me encanto, se sincronizo lo mas bien con mi actual calendario, lo veo mas rapido y con toda la informacion accesible! Me gustaria que la estetica estuviera de otra forma pero me gusto y la recomiendo
  • (2022-03-17) Walter Tapia V.: Excelente aplicación!
  • (2022-03-04) Ulukan Tezcan: Gayet iyi. Sorunsuz çalışıyor.
  • (2022-03-02) Nicole Abaya (Nikki): thank you this is great
  • (2022-03-01) Munem Shahriar: nice. loved this extension
  • (2022-02-27) Kants Niat: Great job, love it
  • (2022-02-10) Forrest Flagg: Update 1 Star to 4 Stars: Jason reached out with some instructions about how to solve the issue with previous contributions not being recognized (https://jasonsavard.com/wiki/Already_Contributed) and was kind enough to refund my latest contribution related to trying to get access to the dark themes again. Having that issue resolved fixes the only real problem I had with the extension, which was that it was frustrating to use on multiple machines and browsers due to having to pay multiple times to access the single feature I truly care about across all my devices. Otherwise, the extension works fine. I only use it as a basic calendar viewer to see what I've got coming up so I can't speak to any of the more advanced features. That being said, there are enough configuration options to let me choose how to display events in a visually pleasing and logical manner. In my search for a decent calendar extension most of the other options failed that basic test.
  • (2022-02-02) 익명의 까마귀: My life is divided into two parts: before this, and after this.
  • (2022-01-05) Vladimir Bardyuzha: В последнее время заметил, что некоторые события просто игнорируются и не отображаются как ближайшие, даже после обновления данных вручную.
  • (2021-12-10) Himanshu Dev: Wonderful extension. Appreciate the work behind it.
  • (2021-12-01) Yulai Zhao: a lot better than official addon
  • (2021-11-30) Pablo Thyago: Não atualiza a opção de lembrete na extenção. Eu utilizo 90% do google agenda lembretes, pra lembrar de tarefas de repetições diarias.
  • (2021-11-09) Kums Murugesan: By far, this is the best Calendar Addon. Thanks for making this useful app. :-)
  • (2021-11-04) Tien Dat Nguyen: Quá là tiện ích, tuyệt zời!!!
  • (2021-10-19) Pablo Laso: Probably the most useful extension that I have! Jason is an outstanding developer, and has implemented everything you may have even not thought about. The only limitations are those that are unfortunately already given by Google Calendar API itself. Amazing job! Congrats
  • (2021-10-16) Lunno: Awesome!
  • (2021-10-14) Jeffrey Zie: This thing is so dang clutch, i had to buy the paid version. It's been almost 2 weeks since i've had it & it's been the most productive 2 weeks i've had in months.
  • (2021-10-11) Donny Peter: Maybe I missed to read some instructions. But shouldnt it be plain straight forward?! My attempt to add a calendar entry failed (even after clicking the "red" button). Even after multiple attempts, not able to add events to calendar. I dont want only all-day calendar enteries. Its useless if it doesnt allow me to set a time.
  • (2021-09-30) Hé Lène: fonctionne super bien, mais j'utilise un logiciel qui doit rester en plein écran (grid3) et la notification est lue par le programme, mais reste derrière la fenêtre (alors qu'elle devrait venir par dessus) donc elle est invisible ; est-ce que j'ai raté un réglage ?
  • (2021-09-21) Esteban Villa: No me deja entrar con google
  • (2021-08-23) Matthew Jardine: This extension is excellent. I manage six Google accounts. This extension, along with the Checker Plus for Gmail, are a massive contributor toward keeping me sane. I especially love that it remains signed in. I clear my browser data regularly, and having this extension just keep working (no need to sign in again), is wonderful. A lot of the complaints in other reviews here have more to do with Google's APIs and permissions than it has to do with Jason's work. Ultimately, you are still using Google's platform, syncing and feature set. Well done Jason.
  • (2021-08-19) Dawid Ślazyk: Bardzo prosta i szybka obsługa. Rozszerzenie działa sprawnie. Brakuje mi tylko funkcjonalności dodawania załączników do wydarzeń (umożliwia ją chociażby aplikacja Kalendarz Google na urządzenia mobilne).
  • (2021-08-05) Alex M: Great extension! Use it ever day
  • (2021-07-16) Rishelle Calunod: it would be nice if dark mode is free, it would totally save our eyes
  • (2021-07-14) Toby Wilson: Absolutely brilliant.
  • (2021-07-11) Jeff Axelrod: Looking to be an essential extension. Does much more than I could have asked for.
  • (2021-07-08) Simon L: This extension is an absolute MUST HAVE and I cannot believe I have lived all these years without it to be honest! All the reviews on here that are complaining about tiny little faults should perhaps think about the fact that this app is F R E E ! Jason has made this and many other incredible extensions for us to enjoy completely free! There is the option to contribute to the projects financially , which I have done, but this is certainly not mandatory and the extensions work 100% perfectly without contributing. This calendar extension and his gmail extension have honestly made my work and personal day so so much easier. I was constantly missing emails and calendar notifications before as they would go off on my phone but that is on silent when at work and I am glued to my PC screen. So I would have to remember to constantly go back to my open Gmail or Calendar tabs to keep up to date. With this extension I no longer have to have this anxiety all the time and can simply relax, knowing it will do all the work for me. This also comes with notifications that are built into windows and you can delete or snooze right from the notification. Something I love , as I can get rid of rubbish in one click instead of having to go into the actual web app to perform these actions. Jason has truly thought of everything with his extensions, they have so much functionality it is unreal. I already feel so much more organised and less stressed out and I have only been using them for 1 day! You need not have any doubts about downloading these trust me, I have tried many others and nothing on the web store compares to these, go ahead and download them now, you really will not regret it! Thanks so much Jason for all your hard work on this and your many other creations, truly awesome! Keep up the amazing work!
  • (2021-07-07) Wesam Alalem: A great extension for quick Google Calendar management.
  • (2021-07-03) Robin Lee: I Absolutely Love this App! It took a little time to learn how to use it, but once I did, Wow! No, more forgetting birthdays, appointments and other activities. This is a Honest Review...
  • (2021-07-01) Stephanie ScarFolk: JUST What I needed! Just installed it, pinned it then set a date and it works flawlessly. Was even able to send invite to hubby to let him know of the event!! Works perfectly with Opera GX!
  • (2021-06-30) Beatriz Silva: Eu amei demais essa extensão e a sincronização dele com o calendário do google. O meu trabalho exige muito do meu acompanhamento em determinadas situações e com ele consigo além de criar um "lembrete" ter a opção de lembrar de novo em um intervalo de tempo. Ainda tem a opção de selecionar um texto em qualquer página que contenha uma data por exemplo e clicar com o botão direito e já jogar para o calendário. A versão free até o momento me atende bem, espero que não mudem.
  • (2021-06-06) Graham Ivany: What a scam, a 'free' app that wont let you do anything unless you subscribe
  • (2021-06-04) Natanael Silva: Ajuda imensamente na organização do dia-a-dia, lembrar os eventos e reuniões, saber quanto tempo falta para a próxima reunião. Melhor extensão do Chrome Web Store.

    I have a situation where my voice notifications though cleared get reactivated and repeated. Going back weeks. This is highly irritating and started when 1. I upgraded to windows 8 (Same behavior under 8.1) 2. Chrome took over notifications which were through the extension. I'm running the latest stable chrome on a quad core laptop (HP)
