Tuplet does not work

Selected tuplet, was not able to make a triplet. No good explanations online. Wasted a lot of time.

I love flat…but

I love this composing app but I hate that the advance stuff or the unlimited storage is not free I say you should let everyone have access. But this app is GREAT

Good app but a lot of glitches

When i search an arrangement/song it will play but no instruments are playing please fix

⚠️とてもいいアプリなのに致命的な欠点⚠️

楽譜も完成に迫った時、少し重かったのでファイルを開き直しました。すると入力した覚えのない音符たちが、我が物顔で散らばっているのです!!困惑しながらも受け入れ、手作業で削除していきました。これは序の口に過ぎなかったのです。
さあ!ようやく完成した!最初から流してみよう!と、また同じ理由でファイルを開き直しました。するとなんということでしょう。全ての小節に四分休符が丁寧に並んでいるではありませんか!!!達成感に包まれ心地良かったのもつかのま、私は地獄の休符取り除き作業に取り掛かりました。最後は四分休符がわかめに見えて仕方ありませんでした。バグかなにかで勝手に声部2が追加されていたようです。
その他に欠点はなく、無料版で充分作成できるので油断していました。これさえなければ!かなりくらったので星2つはそのぶん引かせていただきます。なにはともあれ革命的なアプリだと思いました。無料版ユーザーなのにグチグチとすみません!!

Garbage

Do not buy credits. They are useless without the subscription. You can’t even undo changes.

They clearly sell you credits that the application won’t allow you to use properly without a subscription. I want my money back. The score it scanned is useless since I tapped something and it changed a note, and even reverting to a previous state is a paid feature.
