First app to actually work for me!!!

I’m diagnosed with severe ADHD and a long list of more things that aren’t necessary, and no matter what method or app I tried to work w/, it always backfired. This app kept me focused AND wanting to work more!! I never thought I would be so invested in studying lol.

Lots of things in the app are customizable, so it’s a relief knowing I can make things work better for my liking. I also adore how when i open a blocked app there’s no bypassing it:)! And the collectable oysters per session are so cute <3 I’ve told a bunch of my friends about this app. Can’t wait to see it get more popular!

Great features and free!

Good app

Good app i like the pokémon feel to it where you can earn oysters by studying promotes studying because I always want the next oyster

First 5star heh

Luv this app remember me when yall big

Motivating FREE study tool

I love how the basic utilities in the app are free at this time. It allows users to access all features advertised. It is easy to navigate and has been really good for motivation. The app is also visually pleasing and I can’t name another study timer adjacent app thats helped me lock in more.

Can’t add pfp

I can’t add a pfp and it won’t let me sign up

cute and helpful!

I never really cared for the apps that blocked other apps but I wanted to try this and I actually really enjoy it! I found it to actually help me not get distracted, and I really like that app design!

Very nice

Very nice but catching the oysters are so hard even if I’m studying the Max amount of time. It might only be around a 30% max chance or get it and you can only really try once.

I love this app

This app genuinely saved my life, it encourages me to study everyday multiple times because often I don’t have the motivation to but catching the cute little characters makes me want to study more, and the low percentage to catch something means I study even more and there’s still new content. And I have so much study to do before my two physics exams at the end of tri. Thank you so much

Amazing study app, can’t catch oysters :(, pls add study stats

I think that o3 is an INCREDIBLE study app that makes you lock in with a chance at reward after every study session. I think the concept of oysters is so cool (especially for collectors and dare I say pokemon lovers). A downside however, is that it is so hard to catch oysters. One time my parter and I did 4, 3 hour joint study sessions, all of which were to catch a 1 star oyster with a >70% catch rate. Not ONCE did either of us catch an oyster. It’s also almost impossible to catch a 3 or 4 star. Ain’t NO way im gonna study for 3 hours just for a 7% chance at getting an oyster. My parter has a total of 30 hours of study and has yet to catch a single oyster (he only has the 2 oysters you start with when downloading the app).

Overall it’s an AMAZING study app that has made me highly productive, especially as I tend to get distracted by my socials (which can be blocked during your study period). I just wish that the catch rate for 3 and 4 stars were higher for longer period of study and that the presented catch rate of 1 stars at 3 hours (70%) matched the actual catch rate my partner and I have experienced. Also pls add feature of study recaps and analytics, I wanna know how much I studied that day/week

great app ong 🙏

edit: they added notifs omg thank you so much o3sama

might not be a big deal since its just an app for studying and to access the cafe but its quite a waste for a social media feature let alone dms if i dont get notified about my friends' interactions. also not everyone is online at the same time, i try to invite my friends to do an oyster and they might be busy or smth so i literally cant do it with friends everytime like it would be good if i can just leave the session open or smth without having to keep my screen open and wait for ppl to join while im doing other stuff

overall great app tho 👍 defo helps me lock in

Battery guzzler

Handy app for a great space but I arrived with 80% charge on my phone and after 2.5 hours left with 25%. Please update your app so that if it uses mobile data while in-store it does not also use up all my battery. Thank you!

Great social media app for those who need something real and slow in this busy world

Props to the devs for making it feel chill and homemade

Nice app!

It keeps updating and bettering! Great effort~

Best social networking app

O3Space has been instrumental in expanding my social circle with like minded people. Through its app, I’ve connected with numerous individuals and become friends. The platform’s unique blend of digital connectivity and physical spaces vibes fosters genuine and meaningful relationships.
