User reviews

Does not work as intended.

I love the concept and purpose of this app, but whoever built this app didn’t do it properly. When I try to block the apps I need blocked, it does not block it. Or it will block certain apps and won’t block others even if I’ve clearly instructed which apps need blocking. Or the timer also doesn’t work sometimes. It’s so weird. I paid for the subscription and it feels like a waste. Just tried to use the “block now” feature and selected it to block all apps and it still says I’ve selected zero apps to block. Like ???

I want my money back

I need this app!! Would love one that works. The bugs have my apps locked, even when they’re supposed to be unlocked, so I have to delete the app in order to use my
Apps, then re-download the One Block, which forces me through a 10min intro and sign up process, which I’ve already done. In fact, I’ve done this painfully 6 times now. How about not forcing the user through that process every time, or making the bugs go away so I don’t have to delete One Block to access my apps?

Low Customizeability

New app idea is good, however not very happy about customization.

Hoping that over time, preset features are more customizable. As someone who benefits from minimalist aesthetic, it does not allow me to delete “suggested” presets in app nor does it allow me to prioritize the limits I’ve made for myself so that way it shows on the first page or up higher on the tiers.

Additionally, color coding is confusing- somehow I can color code my limits without actually seeing where the color coding organizing is executable.

Also, where can I edit my daily one thing goal?

Lots to fix, despite good app idea. Just hope my investment doesn’t go to waste.

Really good just don’t want to pay for it

I really like this app it would have been perfect for me since top help me focus on school work and not doomscrolling I just don’t want to pay for it because it’s too much money

New Update destroyed everything

I liked the app but the new update is awful. I have no control to stop the feature of earning screen time. Even after completing my „one thing“ it looks everything again. Makes no sense because I need my phone for work etc. Liked the version before way more.
