シャドーイング練習: How To Solve The App Onboarding Paradox - 動画で英語スピーキングを学ぶ
レッスンを作成中...
1
On average, apps lose 77% of their users within three days.
2
Not because they have bad features, not because their marketing is broken,
3
because of one onboarding choice that's either buying you retention or killing it.
4
And most founders don't even know this is the lever to pull.
5
So in this video, I'm going to break down the one rule that flips the 77% number around, the app killing it right now with a two-screen onboarding,
6
and a counter case that breaks the rule on purpose and still wins big time.
7
By the way, I'm Tim.
8
I've spent the last decade designing digital products from big tech to startups all over the world.
9
And the difference between an app that hooks users in week one
10
and an app that loses them in less than three days comes down to one rule that most founders get wrong.
11
The thing is, most apps out there onboard like government forms, sign up screens, permission requests, walkthroughs.
12
By the time the user gets to do anything, they click through screens that to them have seemingly little to do with the value of the product.
13
And if your product isn't heavily dependent on personalization, the fix usually isn't more onboarding.
14
It's onboarding that does the work for the user, not work for you.
15
The clearest example of this is Granola.
16
It's the AI Notes app that raised $125 million in March, 2026 at a $1.5 billion valuation,
17
six times what it was worth 12 months earlier.
18
Their onboarding is two screens.
19
Screen one, signing with Google.
20
Screen two, grant microphone access.
21
That's it.
22
The next thing you do is open Granola during your next meeting.
23
The app records, transcribes, summarizes.
24
The value lands in the very next thing you were already going to do.
25
Many apps in the AI productivity space will onboard with sign up, then a feature tour, than maybe a Goals Wizard.
26
Granola skipped all of that.
27
Just two screens to value and they're growing like crazy.

Now, here's where it gets interesting and counterintuitive.
31
Some of the fastest growing apps in 2026 have absurdly long onboardings.
32
Cal AI is the calorie tracking app that did 35 million dollars in revenue in its first year.
33
Their onboarding is a 20 plus step quiz.
34
Think about that, you answer 20 plus questions before you ever see the product.
35
Noom, the weight loss app worth billions, runs you through 113 onboarding screens.
36
If short was always right, those apps wouldn't thrive.
37
So what's going on here?
38
These long onboardings do two things at once.
39
And this is the key thing to understand.
40
One, they earn a personalized first experience.
41
CalAI asks a lot of questions because without that data, the moment you land on the home screen would feel too generic.
42
Like every other calorie track, the long onboarding is the trade-off.
43
You give up speed, but you get a first experience built specifically for you.
44
Two, they filter for buyers.
45
Users who bounce on a 20-step quiz were less likely to convert anyway.
46
The ones who finish are showing you they have deep pain and willingness to pay.
47
Long onboarding kind of self-selects in that way.
48
That's why it works for Cal AI.
49
Calorie tracking is a deep pain niche where personalization really matters.
50
The quiz is both a buyer qualifier and an aha moment builder.
51
So here's the actual rule to remember.
52
By default, keep your onboarding as short as possible, or better yet, surface tangible value as fast as possible.
53
That's the rule for most apps out there.
54
The exception kicks in when long onboarding buys you something users actually really need in order to stick.
55
Either a personalized first experience that wouldn't be possible without the data or a filter that gets you actual buyers.
56
Apply this and I can assure you that your retention curve will start looking healthier.
57
Now, if you found this short breakdown useful, again, design choices like these are just one of many things
58
that we help founders think about during our free design strategy calls at ZipZap.

61
that most founders never even consider.

Now, until the next one, have a great life.

英語学習に最適な動画の魅力
この動画は、日常的なビジネス英語や論理的な話し方を学ぶのに最適な素材です。スピーカーのTimが明快な語調で情報を伝える様子は、英語シャドーイングの練習にぴったりです。専門用語も少なく、「onboarding」「retention」などのキーワードが自然に組み込まれているため、YouTubeで英語学習をする初心者から中級者まで活用できます。特に、IELTSスピーキング対策に必要な「論理的に説明する」スキルを養うのに役立ちます。
自然な英語表現の秘密
動画の中には、自然な英語の流れを感じるフレーズがたくさんあります。例えば、「The thing is, most apps out there onboard like government forms」は、「実はね、ほとんどのアプリのオンボーディングは官庁の書類のようなものです」という意味で、「The thing is」が口語的な接続詞として使われています。これを使うと、話し手の意見がスムーズに伝わります。もう一つ、「Granola skipped all of that」は「Granolaはそれらをすべて省いた」という意味で、「skipped」が簡潔でパワフルな動詞として機能しています。また、「That's why it works for Cal AI」は「だからCal AIには効果があるのです」という因果関係を明確にする表現で、議論をまとめる際によく使われます。これらのフレーズは、shadow speakの練習で繰り返し口にすることで、自然な英語表現が身につきます。
効果的な練習ルーティン
この動画を使ったshadow speechの練習方法を紹介します。まず、動画を10秒ずつ再生し、その直後に同じ速さで繰り返します。このとき、発音だけでなく語調やポーズも真似ることが重要です。次に、自分の声を録音してみて、元の動画と比較してみましょう。「Is my intonation the same?」「Am I pausing in the right places?」などの点に注意して修正します。1日10分、1週間続けると、英語のリズムが掴めるようになります。特に、IELTSスピーキング対策をしている方は、論理的な展開を真似ることで、スピーチの構成力も向上します。
この動画を活用して、楽しく英語のスピーキング力を上げましょう！
シャドーイングとは？英語上達に効果的な理由
シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
