• (2025-06-17) Sarang Vikram: absolutely amazing interface and superb integration of minimalism .
• (2025-06-13) Shaarvi Pawar: Amazing app...Helped me focus a lot on my studies... it is very accesible and waas really helpfulthat whilegoing on different apps, it still showed how much time was left
• (2025-06-11) Chris: It is unobtrusive, the UI is minimal and straightforward, and the site blocking feature is really handy! Before, I would use Pomodoro websites, and the extensions available at the time were not very unique. It was the site blocking feature that really caught my attention, and I've been using it ever since.
• (2025-05-28) Bob Byrne: A brilliant Pomodoro style tool with lots of functions and more features are on the way. The Pro version is really worth it..it's an investment in your precious time and productivity.
• (2025-05-27) Zeyad Alseed: I love it, it is perfect for me and the developer is nice
• (2025-05-19) Pradeep Srinivasan: I have tried multiple Pomodoro timers, but Otto is one of the easiest ones to use. It integrates seamlessly into your browser when you have the timer running. The ability to autoblock websites, and the reminders to start working when you visit specific websites are also really helpful. The developer is also really friendly and always open to feedback and suggestions. I can't wait to see the future of Otto!
• (2025-05-07) Pgs Gaming: One of the best Pomodoro timer i impressed with the blocker which is work seamlessly and again big salute to otto developers I think they loved to developed this application there is the reason why I love this extension too.
• (2025-03-29) Michelle Kassis: I love this app! Unfortunately, I've noticed recently that when the timer ends, the webpage goes black behind the popup. I have to refresh the webpage to get back to the site. Any suggestions would be so helpful.
• (2025-03-24) Nhan Nguyen: Looks cute and has almost all the basic functions. However, sometimes after a session, a popup appears and blocks the whole page. I cannot do anything to close the popup, the only solution is to refresh the whole page without saving my progress while doing something. It's quite annoying that way. Please help fix it! Thanks for the great work!
• (2025-03-21) Captain America: Amazing extension everything works well, but mini timer feels like obstructive sometimes you can add snap to edge feature which shows only progress bar when it is hidden and visible when mouse hovers over the timer, as it is there in ticktick application minimode, but still, it's amazing extension thanks to Otto.
• (2025-03-20) akshita singh: I love this cutie Otto istg amazing web to focus and exercise
• (2025-02-23) Pranav Narayan: I don't have any bad things to say, this app has made me 100x more productive. I love the design and videogame aspect as well. Good work to whoever is developing this!
• (2025-02-18) Saubir Yaseen: It works well at combining the functions of a timer and site-blocker. Otto is really cute, too! Kudos to the devs. There is one things that keeps this from being perfect, though; it would be nice if you could toggle on an always-displaying timer so you could constantly see the time decreasing. It would be too obtrusive if it was the whole interface that you get when you click on the extension. Instead it could be a small icon in the bottom right corner of the screen with a circular progress bar. I don't know if that's possible, but it would be really helpful.
• (2025-01-31) Vik: Just downloaded today (like an hour ago), and focus timer keeps getting stuck. Seems like I have to click on the extension again, wait a bit and it works again
• (2025-01-29) Eric Shih: Causes a bunch of layout problems on youtube (buttons expanding, scrollbars showing up on video descriptions), took me forever to isolate it to this app as I have no idea why it'd cause so many problems. Update: Fixed, thanks!
• (2025-01-09) Tim Mueller: Love the app. It really helps to stay focused. Is there a mode that it keeps on blocking after 25min. My focus sessions are sometimes longer than 25 min and I like to block for 3 hours for instance. Thanks, for all you do!
• (2025-01-04) Yuefeng Zhou: It doesn't track my times of focus time and total focus correctly. It missed most of my focus events.
• (2024-12-10) Lucas Call: I LOVE this app. Otto is so cute and I can't let him get hurt. I have ADHD and gamification works amazingly when I am trying to focus. There is one suggestion I would like to implement. I would like for there to be a mode where there is a white list or an allowed list so when I turn on this mode it only allows those websites and all other websites are blocked. I get distracted very easily and I start reading an online version of my LED lights instruction manual 😅. I just can't block all the websites that I get distracted with because I get carried away easily. But other than that, it's an amazing extension. Thank you so much for making a free extension for people that have an incredibly hard time studying!
• (2024-12-03) Marie Pauwelijn: I really like this app but thce only thing that sucks is when you're going on another web the timer doesnt stay on the screen and thats really anoying because you dont see otto and then you kind of forget to study😅, can you fix this plssss.
• (2024-11-24) Nazanin Monfared: Hey! Thanks a ton for creating this app. It worked like a charm for me for days, but then it suddenly stopped counting. Now, it only works if I manually stop the timer and restart, and it's really bumming me out. Appreciate any help with this!
• (2024-10-04) Alina Devoogd: I love the extension, I love pomodoro, and seeing it up above. I love the element of gamification and earning points HOWEVER, none of my points or stats get saved whatsoever. It isn't tracking my stuff and I can't find any place in my settings to fix it!
• (2024-09-17) Kimberly Fong: LOVE this extension, but tasks feature is glitchy. Pause buttons not working on both the pop up and the extension. I also set a task to 15 mins but it sets a timer of 30 mins. Other than that, it's one of the best apps out there. I will be using the timer feature more.
• (2024-08-04) Andrea Watt: i love this extension , one of the best pomodoro extension i have ever used. Although I have one request, please please add a stopwatch mode along with the pomodoro mood.
• (2024-07-31) Sagittarius serpentarius: Nice, love the aesthetic and how straight to the point it is. However, its autoblocking does not work properly. Overall, a useful extension.
• (2024-07-12) angel: Very cute and the website blocking is super useful, only complaint is that I wish there was an option to keep the timer on the screen to keep me motivated.
• (2024-07-08) Caleb Cox: Perfect!
• (2024-07-02) Amy Kim: This extension is AmAzInG. I'm one of those people who always get distracted every 5 minutes and goes wandering off to a random site. However, with this wonderful creation my focus is next level. Otto blocks sites, lets you customize the sound, and works along with you. I love this extension and will use actively. Thank you!
• (2024-06-26) Thais Alvarenga: Absolutely love the extension; such a life savior! Besides having all the functionalities for a pomodoro timer (like letting you set how much time you allot for working and resting), it just has the best animation! I LOVE that Otto is working out alongside me. And the page blocker is great. Otto's disappointment when you open a blocked page breaks my heart and makes me want to go straight back to work. One of the best extensions out there productivity, hands down!
• (2024-06-23) Yashika Saini: I love how cute it is......it does not let you get distracted by any site which is not useful and has a Pomodoro timer! It really helped me a lot in my high school exams....the light blue and golden theme is really great and the tasks section too. Now, I can focus so much more on studying Highly recommend it to fellow students!
• (2024-06-19) emievyy: otto is super cute and easy to use. i love the block sites feature, allowing me to focus on my work 100% and not get distracted. 💗💗💗
• (2024-05-25) Louise du Toit: Very nice to use. Would have liked more customization like colors and study goals maybe but over all still very effective and love using it :) The yellow guy doesn't have a face but that will probably get fixed... hopefully. I understand that there is an Otto Pro which mights have more options but the free Otto timer only goes up to 59 minutes which is sometimes irritating. Still great experience
• (2024-04-21) Junk Warrior: This extension is fantastic, boasting a user-friendly interface and strong appeal. While it's generally smooth sailing, I've noticed occasional glitches like the yellow task guy's missing face. One suggestion for improvement would be to introduce a long break feature, rewarding users with extended break times after completing every five sessions. This addition would further enhance its utility and user experience.
• (2024-03-31) pinecone xoxo: It is indeed a very helpful extension to add, but I wish there were clearer details on why some things are the way they are. I do not understand why the graph shows me that I focused for 13 minutes when I did for 50 minutes, and I do not know how Otto's health goes back up. Those are just some things that I do not understand and cannot seem to find anything helpful about them on their website. Also, I really wish they remove the time limit set, I cannot set the timer for more than 90 minutes. Other than that, I love the reminders to focus, and overall it is just a cute work/study buddy.
• (2024-02-26) Ali Abuhamra: love it
• (2024-02-12) saee: I can't extend the timer upto 90 minutes, It is designed only for 50 minute sessions. Please improvise if you can!!
• (2024-02-01) Avisha: bess app for studying
