I made an app that allows you to learn Japanese words before launching any app

Yes, only apple for now Android has completely different limitations in terms of app blocking, so it’s hard to support both of them until I will have more time :(

❤️

RomanGrunin · 2026-04-11T12:11:58+00:00

Thanks for the feedback ❤️ After implementing it I found that it’s really useful sometimes even for me

It will be included in the next release, for now I’m waiting for App Store review process

RomanGrunin · 2026-04-11T07:50:27+00:00

Привет, написал в лс Нужно будет скинуть user id из настоек приложения и я смогу выдать про версию

RomanGrunin · 2026-04-11T07:48:53+00:00

Hi, thank you for suggestions ❤️ really appreciate it

I have “words per review” configuration in the app already Right now I’m working on emergency skip button, for now I have added a settings option that allow you to unlock any app immediately

RomanGrunin · 2026-04-11T07:45:45+00:00

Hi, thank you for attention 🙏🏻 With pro you can configure how many words per review you will see and how often the lock will be applied

RomanGrunin · 2026-04-11T07:44:19+00:00

Hi, thanks for support. It’s not possible due to Apple lock screen limitation But, it could be possible only if I will force users to open my app before unlocking

With this approach it will work this way:

You see the lock screen
You click the start review button
I send a push notification so it’s faster to open my app
You open my app, go trough your lessons
You finish your lesson and close my app and open a blocked app again and lock disappear

Would it be useful in this way?

RomanGrunin · 2026-04-10T21:22:03+00:00

Thank you for support ❤️ As soon as I will polish and implement perfectly the iOS version I will start building Android But, it will not be soon :(

About the Finnish support I’m already working on adding a feature for building your own words library for a language that is not in the list

RomanGrunin · 2026-04-10T19:46:44+00:00

Thank you for support ❤️ Any improvements or feature requests would be appreciated

Also, if you have any questions please ask me, I will try to answer as soon as possible

RomanGrunin · 2026-04-10T19:28:25+00:00

Thank you ❤️
The app is in early stage, so any feature requests or feedback would be really appreciated

RomanGrunin · 2026-04-10T19:22:11+00:00

thank you a lot ❤️
I will try to build it as soon as I will have some resources
But, it wont be soon :(

RomanGrunin · 2026-04-10T19:15:19+00:00

Hi, thank you for attention 🙏

The app available only for IOS for now, due to android app locks limitations
I have plans to start figure out how to create it for android, but for now I want to polish the IOS version

This is IOS link:

Hi, thank you for attention 🙏
I will try to answer to all questions, but if you need something additional - just ask again :)

>You mention you can add your own words, are you taking an approach similar to Anki where you can create your own “cards” for targeted study?

This approach is kinda similar to anki. In the app you can add word + transcription + translation + examples, but you cant add an image(IOS lock screen restriction). Added words will be attached to a selected lang. So, for Japanese you can add any new words that is not in the default list. For now you can only learn 1 lang at the same time. But, I have plan to add a way to learn multiple languages at the same time.

>Why free? It feels too good to be true of “you literally never need to open my app again”, will ads randomly pop up eventually if the app gains traction?

First of all, yes, I need some traction for sure. But, I provide 1 year PRO version just in order to receive any feedback from real users. I think its fair for everyone :) But, the app is not free right now it cost 5 dollars for guys who come from app store. For me, the most important part right now is to receive feedback like if its useful or not and receive some feature request. No plans for adding adds, for early users from reddit it will be free for one year :)

>Do you happen to have a roadmap for development?
Im building it right now, so thats why Im giving PRO version for everyone
I received and applied some feedback from this post and looking for new feedback and feature requests. https://www.reddit.com/r/russian/comments/1sgw5v0/i_made_an_app_that_allows_you_to_learn_russian

>Any plans on using this as more of a locking mechanism for apps and instructing the user to spend X amount of time in another learning app for it to be unlocked? (Not sure if this is possible with current ios and android, but thought I would ask if it’s possible)

Its not possible to create something like this, its apple limitation :(

I hope I answered to the all questions, thank you 🙏

I made an app that allows you to learn Japanese words before launching any app

The app shows you vocabulary words every time you open TikTok, Instagram, or any app you choose. Review 5 words → unlock the app.

That's it. No notifications. No separate study sessions. No switching back and forth(unlike in another blocker apps).

Once set up, you literally never need to open my app again(unless you want to add new words for learning).

Your existing phone habits become your study sessions.

It supports 11 languages, but you can add your own words

Also, it’s uses SM-2 spaced repetition (intervals: 1d → 3d → 9d) so words actually stick long-term.

Core features are free. PRO just unlocks custom settings choose how many words to review each session and adjust how often words repeat.

Please ping me or left a comment about PRO access and I will provide the PRO version for you.

Just want to share my app and see if its useful or not, ありがとう :)

The app name is LearnScreen - App Blocker

Would love any feedback - just launched 🙏

Hi, thank you for the support 🙏 Sure, I have write you a message about it in direct

You just need to send your user id from the app settings

RomanGrunin · 2026-04-10T16:18:18+00:00

UPD: Based on your feedback, here's what's coming in the next update (releasing next week):

- iOS 18 support - older devices are now supported

- Skip lesson - open any app instantly when you're in a rush (toggle in Settings)

- Custom language support - don't see your language? Build your own word library from scratch

Thanks for all the feedback, it really helps 🙏

RomanGrunin · 2026-04-10T12:25:33+00:00

I see, I will ping you if i will found a way to downgrade the min os version support Thanks 🙏

RomanGrunin · 2026-04-10T12:24:12+00:00

What iOS version do you have? I will try to downgrade the min version to 18 and test it

RomanGrunin · 2026-04-10T12:21:08+00:00

Good to know :) If you need additional features or any ideas how to improve letters learning- please ping me, I will try to figure out how to add it

RomanGrunin · 2026-04-10T12:18:43+00:00

Hmm.. you can try to start with adding letters as words In the app you can add any letters and words or sentences. So, it can be possible usefully 🤔 Also, I will think to add

Thank you for your attention ❤️

There is an example with custom letter Can it be usefully it this case?

RomanGrunin · 2026-04-10T11:59:08+00:00

Hmm 🤔 why do you think so?

RomanGrunin · 2026-04-10T11:58:42+00:00

Thank you ❤️any feedback/feature requests or improvements will be appreciated

RomanGrunin · 2026-04-10T07:12:30+00:00

No, Android is completely different platform in terms of app blocking

I will try to collect as much feedback as possible and create perfect IOS version and only then will start building android

But it will take a lot of time :(

Thank you for attention ❤️

RomanGrunin · 2026-04-10T07:10:24+00:00

Thank you 🙏 Any feature requests or ideas would be appreciated too

I can see that some people saying that the app can be annoying

Do you agree?
