## What is Komoriba?

Somewhere inside your phone,
tiny residents have made themselves at home in a place called Komoriba.

Animals, robots, and all sorts of curious little characters.
While you're focused on your work,
they're busy doing their own thing in their cozy rooms.
And honestly? They're ridiculously cute.

◆ Focus Timer
Start a focus session and your residents get to work alongside you.
The longer you stay focused, the more Crystals you earn.

◆ Screen Block
Block distracting apps while you focus.
The more apps you block, the more Crystals you'll pick up.

◆ Focus with Friends
Find a public room, or get together with an invite code or shared link.
Even when you're apart, your Komoriba can focus side by side.

◆ Discover New Komoriba
Spend your Crystals to unlock rooms you haven't seen yet.
Each one is home to different residents.
The more you focus, the more of this world opens up to you.

◆ Community Komoriba
You can even request your very own original Komoriba.
A room born from your imagination might just help
someone else find their focus too.

◆ Komoriba Supporter (Monthly Plan)
Want to support the world of Komoriba?
Supporters earn double Crystals from focus sessions,
receive bonus Crystals every month,
and get access to supporter-only rooms.
Your support helps this little world keep growing.

◆ Crystal Shop
Can't wait to meet a certain Komoriba resident?
You can grab Crystals anytime to unlock them right away.

Studying, working, or just getting things done.
Whatever you're up to, your Komoriba residents are right there with you.

### 5/5 — 操作簡単、作業捗るかわいいアプリ

*2026-08-06*

レビュー初めて書きます。

このアプリは、タイトル通り操作簡単、作業捗るかわいいアプリです。

時間を費やすほど新しいこもりばをお迎えできるので、勉強が捗ります。

作業のやる気が出ない人や、かわいい癒しを感じながら作業をしたい人にとてもおすすめです。

### 5/5 — 入れないと損です！まじで！

*2026-08-02*

最高！
私は小学生ですが、勉強とかめっちゃやる気になります！
ロックできるアプリなので、タイマーしている時は、使えないようにできます！
タイマーしている時間によってもらえる、コイン？みたいなのでキャラクターがいる部屋みたいなのが買えます！
たくさん頑張るとたくさんかわいいキャラクターのいる部屋がゲット出来ちゃいます！！
最高なので入れるべき！！
月額500円でオリジナルのキャラクターのいる部屋も作れます！！

### 5/5 — やる気が上がる

*2026-07-05*

勉強をするときに使っています。
やる気が無くても、とりあえず初めは10分だけやって、そこからずるずる時間を伸ばして気が付けば勉強が進んでる、みたいな感じになっています。

BGMがとても安心できて集中もできます

ただ、時間を設定するとき、バーが動かしにくかったりするので、入力して設定出来るようにもしてほしいです。

それと、プレイリストの名前変更の時に上手くキーボードが出てこない時があります。
(iPhoneを使ってます)
バクかよく分かりませんが、対処していただけると嬉しいです

それ以外は本当にいいと思います！

拙い長文失礼しました

### 5/5 — 自分時間のおとも。

*2026-06-25*

子供を寝かしつけた後に自分の部屋でbgmを聴きながら勉強や読書をしています。やさしい音楽に癒されなんとも言い難い極上のひとときです。
素敵なアプリを生み出して下さりありがとうございます。できることならこれから先もずっと利用させていただきたいです。

### 5/5 — 勉強のお供に使用しています

*2026-06-17*

累計の勉強時間が見たくて使用していますが、シンプルで使いやすくて重宝しています！
ある時から画面上部のバーに残り時間が出なくなってしまい、通知センターにも出なくなりました。
今既に何分やってるんだ、とモチベーションになっていたのでとても残念です。こちらの設定の問題でしょうか。

### 5/5 — かわいいでs､､､

*2026-06-14*

勉強して動物見たらガチ癒されてまた勉強に集中できます！だけど、追加して欲しいのは、クリスタルの使い道を増やして欲しいです、例えば、クリスタルを使って動物に洋服を着させれるなどそういうのができたらいいよ思います！！これからも頑張ってください❤️

### 5/5 — やる気出る

*2026-05-16*

本当に可愛い。毎日部屋が増えてて数字が増えているのをるたびに凄くわくわくする。
でも作業中に寝落ちしたりするので、報酬を受け取らないというボタンも欲しい。
また、図鑑が追加された時、図鑑マークに通知マークみたいなのをつけて欲しい。
毎日見に行くよりそっちの方が嬉しい。

### 5/5 — 今まで使ったアプリの中で1番良い

*2026-05-05*

勉強タイマーアプリでよくある、UIから生じる地味なストレスが全くなく、とても気に入っています！余力がありましたら、Applewatchからも使用できるようにして欲しいです！

### 5/5 — 優秀すぎる‼︎可愛くてやる気が出る☺️

*2026-05-03*

これを始めてからめっちゃ作業捗ります！
他の人とできるのも、モチベになっていいです👍

本当に本当に小さな要望なんですけど、
プレイリストを作る時どれがどの曲か聴けるようにして欲しいです…

### 5/5 — 可愛いこもりばが沢山増えて嬉しい☺️💞

*2026-04-27*

感謝と応援の気持ちを込めて、ささやかですが課金を継続しようと思っています！
課金も制作依頼も良心的すぎる設定なので、嬉しい反面、ご負担が大きいのではないかと勝手に心配してます。
バランスが難しいと思いますが、課金要素が増えても良いので、持続可能な形で続いて欲しいアプリです！
