Étude 是一個為喜歡彈琴的人而做的練習記錄。 它很簡單:按下開始，練你的琴;按下停止，時間就靜靜地留下來了。 這裡沒有排行榜、沒有連續紀錄、沒有每日目標、也沒有任何通知在催你。練習不需要被遊戲化，也不需要壓力——你和你的琴之間，本來就已經足夠。 Étude 只做三件事，而且把它們做得安靜: ・記錄每一次練習的時間 ・整理你正在練的曲目,看看時間都花在哪幾首上 ・讓你回頭,看自己一路累積了多少 剛開始，它只是一個數字。但練習會一天一天疊上去——一個月後、一年後再打開，你會發現自己走得比想像中遠。而這一切，都是你親手彈出來的。 沒有比較，沒有催促。只有你、你的琴，和屬於你的時間。 打開它，然後去練琴吧。

Verdict
The clearest difference is update cadence: Étude at every 2 days against QR's every 5 months. QR's advantage is iOS requirement (14.0 vs 16.4). On price, ads, in-app purchases and device support there is nothing between them.
