## What is TimeSignal Alarm clock?

This alarm will wake you up with sounds and time chimes that you can't ignore.
Doorbell...can you ignore it?
Repeated Doorbell...can you ignore it?
It will repeatedly tell you the elapsed time at one-minute intervals.
It will also tell you the time on the hour and at times divisible by five.

--------

It's simple to use.
Just set the alarm time and close the app.
When the time is up, you will be notified by voice.

The alarm will continue to ring for 30 minutes if you leave it alone,
so start the app to stop the alarm.

The way to stop the alarm is to match the pictures.
Match the pictures, top and bottom as a pair.
Match all three pairs and wait 2-3 seconds.
A button to stop the alarm will be displayed.

Please note that the alarm will not stop if you match the same pictures in a horizontal row.

You can change the difficulty of the picture matching.
You can also set it to stop with one button.

You can check the difficulty of the game in a test.
It would be helpful if you could check the operation once before using the alarm.

You can register up to eight alarm settings.
It is convenient to set the times you frequently use in advance.

Notes about this app:

※ Uses the voice notification function of the iPhone/iPad itself.

If you do not allow notifications,

the alarm function will end when the app screen is closed.

This app sleeps according to the iPhone settings, so the app will essentially be unusable.

※ Sleep is disabled when the alarm stop screen is displayed.

Please note that no sound will be heard if you are in silent mode or have the notification function of the iPhone/iPad suppressed.

※ If you leave the alarm on the lock screen for 30 minutes, the next alarm will not sound.

In that case, please launch the app.

(The next alarm will be automatically reset when the app is launched.)

Don't expect music from this app.

There is no music at all.

The time signal of this app is not suitable for any purpose other than as an alarm.

It is a powerful alarm, but it only sounds for 30 minutes.

Humans sleep in 90-minute increments, with deep and light sleep alternating, and an alarm app cannot wake you up during deep sleep with sound alone.

If you really want to wake up at that time, it would be helpful to use multiple alarms so that you are aware of it before the time you want to wake up.

If you want to wake up 30 minutes earlier than usual, it would be helpful to go to bed 30 minutes earlier than usual.

*To Apple Watch users

We apologize for the inconvenience, but please select the Notifications tab from the Watch app on the iPhone home page and set it so that "T.Signal Alarm" notifications are not forwarded to your Apple Watch.

If this is not set, notifications will be forwarded to your Apple Watch and the app will not work properly.

## Key features

- Loud, unignorable alarm sounds
- Voice notifications for time
- Picture-matching puzzle to stop alarm
- Adjustable alarm stop difficulty
- Up to eight alarm settings
- Time chimes on the hour and at five-minute intervals

### 2/5 — フリーズします。

*2025-12-29, version 3.9.06*

最初は、順調に設定できていたのに、次開いたらフリーズしてギンガムチェックのみの画像がチカチカ色が変わるだけです。
iOS26を使用しています。早急な改善お願いします。

### 1/5 — フリーズした

*2025-11-21, version 3.9.06*

1回も使えずに、ギンガムチェックの画面でフリーズして再起動しても反応ありません。。

### 1/5 — Honest Review of TimeSignal Alarm Clock

*2025-07-07*

I tested TimeSignal Alarm Clock hoping to find an alarm that would wake me up effectively, without music, and especially without causing stress. I have a heavy sleep, so I need a voice that is loud, clear, and natural—ideally in French, but I understand the app is only available on the US store.

What I Need: 

	•	An alarm that wakes me up reliably, without stressful or aggressive sounds.

	•	A natural, strong voice that repeats the time until I get up.

	•	A French-speaking option would be perfect, but at least a pleasant voice.

My Experience
	•	The voice used by the app is robotic, unnatural, and only available in English. It feels impersonal and even a bit stressful first thing in the morning.

	•	The alarm includes extra sound effects (like motorcycles, glass breaking, etc.) that are jarring and not helpful for a calm wake-up.

	•	The interface is inconsistent: sometimes the buttons appear, sometimes they disappear, which makes the app confusing to use.

	•	Setting the exact alarm time is tricky—if you go past the time you want, there’s no easy way to go back.

	•	To stop the alarm, you have to play a mini-game with emojis, which is not what I want when I just need to wake up efficiently.


What Would Make It Better

	•	A natural, human voice (not robotic), ideally with a French option. 

	•	Clear, simple interface with reliable buttons.

	•	No extra stressful sounds—just a voice announcing the time loudly and clearly, repeating as needed.

	•	Easy alarm setting, with the ability to adjust the time up or down.

Conclusion: 

If you want an alarm that wakes you up gently but firmly, with a natural voice and no unnecessary stress, this app is not the best choice. The robotic voice, stressful sound effects, and confusing interface make it hard to recommend, especially for French speakers or anyone sensitive to harsh sounds. I hope future updates will offer a choice of natural, human voices and a more user-friendly experience.

### 1/5 — BUYER BEWARE!!!ALARM WILL NOT SHUT OFF!!!!!

*2024-11-10*

What good is an alarm clock that will not shut off even after matching the emojis??? 
I would definitely not recommend purchasing this app before this issue is addressed and solved!

**Developer response:** Did a green bar appear when you matched the top and bottom emojis?
I believe this is a misunderstanding caused by the system that matches the top and bottom emojis, so we will change the system as soon as possible.
I apologize for any inconvenience caused.

### 1/5 — Nope

*2024-10-07, version 3.6.01*

Could not close the app. Could not open anything else. This app basically hijacked my phone! Avoid.

### 1/5 — アップデート後

*2024-06-25, version 3.6.00*

以前のように、
曜日を設定出来るように
して下さい。
オフにしているのに、
勝手にアラームが起動した。
休日とで分けていたのに、
仕事中の日、
アラームが鳴って大変だった。

### 4/5 — 今後に期待しています

*2024-06-15, version 3.5.10*

購入して試したのですが、バッジ❶がずっと消えてくれません。 改善して頂きたい事が色々あります。 ・アラームを未設定の場合でバッジが残っている事。 ・アラームをストップさせる為のクイズが要らない。 ・操作性が悪いです。 ・横向きのみでは無く、縦向きにも対応して下さい。 正常に動作しない場合は返金リクエストさせて頂きます。よろしくお願い致します。

･･━━･･━━･･━━･･━━･･━━･･━━･･

「ご購入ありがとうございます。 ご要望の件ですが、 １、アラームを未設定の場合でバッジが残っている事。 これは例えばアラームがなる前に早く起きてしまった場合、 当然、利用者がアラームをオフにすると思うのですが、 そのアラームがオフになっていて翌日以降、アラームが鳴らないという 警告のための表示です。 設定項目を追加して機能を有効にするか無効にするか設定できる様にします。 ２、アラームをストップさせる為のクイズが要らない。 すでにこの機能は実装されています。 アラームの設定を「１タッチ」に変更してください。 ３、操作性が悪いです。 具体的にどの様に変更すればよいのでしょうか？ 縦向きの画面デザインに対応すればよいのでしょうか？ ４、横向きのみでは無く、縦向きにも対応してください。 すでにアプリが横画面に特化したデザインになっているため、縦画面に移植が難しく 対応には２、３ヶ月かかると思います。 前向きに対応を実施しますが、時間をください。」

･･━━･･━━･･━━･･━━･･━━･･━━･･

１、ユーザーへの親切設計だと理解しました。失礼しました。確かにと納得できました。バッジが気になれば、こちらの端末でバッジ表示をオフにする事もできるので。こちらは大丈夫です。

２、「１タッチ」で試して見ました。しかしゲーム自体が不快と言うか、絵文字がデカデカと出てくる事やアラームを停止する為だけのシンプルなボタンを中心に欲しいです。問題は画面領域ギリギリまでフォントなど大きめに作られている事が「大きすぎて逆に見づらい、使いづらい」と感じました。

３、Apple純正のアラームの様に時分を表示させ、スライダーでスクロール入力や手打ち入力で行える様にして欲しいです。UIの問題だと思いますが。
現状、午前午後→時→分→ゲーム→セット完了。と言う形ですが、上下の数字をタップして設定はスマートではない、スタイリッシュでは無いと言う個人的な違和感です。また、アラームを変更したい場合でも左上の【編集】を押してからなど、何テンポか押さないと時刻設定に時間がかかります。慣れもあるとは思いますが、このやり方は手間です。
『時報で知らせてくれるアラーム』と言うのは凄く魅力的で色々なシーンに活躍できると思って購入しましたが、UIがどうしても古臭く感じてしまいます。
こちらのアプリを継続して使うもの、このアプリを素晴らしく思う方も多いと思うので、これも一興だと思います。ですが、最低でもカラー変更などできれば有り難いと思っています。背景をブラックにしたり、個人の好きなカラーにできるプリセットを用意して頂きたい。どうしても配色が気になります。

また、通常こちらのアプリではアラームのみと言う訳では無く、時計表示の役割が大きくあるかと思います。私個人はアラームさえ使えればいいのですが、個人1人の意見ではUIを大幅に変更する事は難しく思いますが現状でも必須だと思う事があります。
〝アラームの時刻を確認したい場合〟であっても画面をタップしてアラーム画面になった時に【完了】を押さなければ時計表示には戻れません。その場合でもプッシュ通知、通知音が鳴ってしまう事です。
アラーム設定をしたい場合は【アラーム】もしくは【プラスキー】を配置して、そこから編集などできれば無駄なプッシュ通知を受け取る事なく済むと思います。

４、縦向きの件は上記を踏まえて、新しくアプリを設計してリーズナブルで買い切りを販売して頂ければ必ず購入させて頂きます。
「しゃべる時報」と言うのに惹かれて購入したので、Apple純正のアラームの様なUI。Apple純正の時計のアラームが1番見やすく、ダークモード且つシンプルで視覚的にも分かりやすい。そこに時報が加われば最高のアラームアプリになると思います。
または、個人的に気に入って使っているアラームは「通知メモ2 - 忘れ物防止のリマインダーアプリ」です。

まだ一度しかアラームを使っていませんが、時報は本当に助かります。知り合いなどにオススメできるアプリに様なアプリになると期待しています。

### 1/5 — Screen is off-center

*2024-01-25*

On my iPhone 15 Pro, the screen is off center. And too large.

**Developer response:** Fixed the app.

### 3/5 — Great app, but please fix clock for 2024

*2024-01-21*

As soon as you turn the alarm off, I mean try to turn the alarm off the application crashes, please fix clock version three point something. Thank you.

**Developer response:** I apologize for the inconvenience.
Fixed crash when stopping alarm clock in version 3.2.15.
Could you please update the version?

### 1/5 — No se puede detener.

*2024-01-19*

Es mala. No se puede detener.

**Developer response:** Pido disculpas por las molestias causadas por mi explicación insuficiente.
Puedes cambiar el nivel de dificultad del juego que detiene tu alarma.
Si cambia la configuración, la alarma se detendrá con un solo toque.
