So what's happening here?

現在是怎麼回事？

Well, that's me.

這是我。

And that's my friend Aldo.

而這是我的朋友 Aldo。

No, really, his real name is Aldo.

真的，他真的叫 Aldo。

I checked his Costco card and everything.

我檢查過他的好市多會員卡了。

I don't know who you're thinking of, but this Aldo is an actor who sometimes likes to hide around town and help me test location sharing apps.

我不知你心裡想的是誰，但這個 Aldo 是一名演員，他偶爾喜歡玩躲貓貓，讓我測試位置分享應用程式。

Yeah, it's great.

沒錯，棒。

My whole life people have been adding a W to the beginning my name.

人們很愛在我的名字前面加一個 Ｗ。

Like it's so funny.

很有趣嗎？

Anyway, Apple's Find My Friends location sharing and Google Maps and an app called, Life360, have become very popular amongst groups of friends and families.

總之呢，Apple 的位置分享應用程式「尋找我的朋友」、Google 地圖與一個叫 Life360 的應用程式最近在許多朋友與家庭中流行了起來。

They all work similarly.

它們的原理相似。

You share your real time location with a person, and maybe they share it with you, and then you can see each other on a map, right down to the specific address.

你跟某人分享即時地點，或許那個人也分享給你，然後就能看到彼此在地圖上，附帶確切地址。

Yes, it can be very, very precise.

沒錯，它們可以非常、非常地精準。

Creepy?

可怕嗎？

Absolutely.

當然。

But there are some good reasons to use these.

但也有用這些應用程式的好理由。

And if you're convinced, which one's best?

那如果真的要用，那款軟體最好？

That's why Aldo's here.

這就是 Aldo 在這的原因。

Wait, where's Aldo?

等等，Aldo 呢？

Aldo has an iPhone on him with those three location sharing apps.

Aldo 身上帶著一支載有那三款位置共享軟體的 iPhone。

I requested his location through each of the apps, and he accepted.

我請求他分享位置訊息，他也都答應了。

He also has the ability to turn off location sharing with me at any time.

他隨時都可以取消分享位置訊息給我。

But before we get into which one works best, let's consider why you may want to track someone like Aldo or why you may consider someone tracking you.

在探討哪款軟體最好用之前，讓我們來思考一下，為何你會想追蹤別人 (像 Aldo) 的行蹤，或你為什麼想讓自己的行蹤被知道？

I have two reasons.

我可以提供兩個理由。

Number one: meeting up.

第一，會面。

Whether you're meeting a friend in a park or at a restaurant, you can see your whereabouts instead of texting back and forth.

不管你和朋友約在公園或餐廳，你可以直接從軟體上看到彼此的位置，而不是來回傳訊息確認。

Google and Apple let you limit the sharing of your location to different periods of time, say an hour or two.

Google 與 Apple 允許你限制與別人分享位置的時間，如一或兩個小時。

Or you can choose to share indefinitely.

你也可以選擇無限期分享位置。

Number two: safety.

第二點，安全性。

People use these services to make sure friends have gotten home okay in a cab or Uber.

人們會利用這些軟體來確保朋友已安全搭計程車或 Uber 到家。

Parents use this with kids of all ages.

父母也可以用來看孩子們的行蹤。

Focused on families, the Life360 app has features for tracking new drivers.

專注開發家庭市場，Life360 能追蹤新手駕駛的狀況。

Of course, there are plenty of reasons not to track.

當然，也有許多不分享位置的理由。

Notably, you give up your own privacy.

特別是，你得放棄自己的隱私權。

And also, you can get anxious when the tech doesn't work right.

再者，你可能會因為軟體的不精確感到焦慮。

Also, stalking, yes, the list goes on.

還有跟蹤，諸如此類的。

If you decide to share your location, make sure it's with someone you know and trust.

若你決定要分享自己的位置，請確保是分享給你認識且信任的人。

Okay, so which one is the best?

好，所以那款軟體最好用？

Test one: standing still outside.

測試一，在戶外定點不動。

Let's see which of these let's me find Aldo outside the easiest.

讓我們瞧瞧，哪款軟體可以讓我最快找到 Aldo。

So all three of them seem to have him in the same place.

這三個軟體似乎都顯示他在同一個位置。

Guess if I bear to the left here, sort of by the water.

在這裡應該要稍向左轉，他似乎在水邊。

Winner of test one...

測試一的贏家為...

Found you.

找到你了！

Never.

才怪！

Apple and Life360.

Apple 與 Life360。

They plotted him faster and more precisely.

它們定位得更快更精準。

Test two: on the go.

測試二，移動中。

But what happens when Aldo is in a car or a horse.

如果 Aldo 在車上，或是，一隻馬上？

Each of the apps update location at different intervals.

每個應用程式更新位置的頻率間隔不同。

If you have Apple's app open it will refresh every minute.

Apple 的應用程式開啟時，會每分鐘更新一次。

When Life360 is open, it refreshes every three seconds.

而 Life360 在開啟時，則是每 3 秒更新一次。

Making it way easier to keep tabs on a moving vehicle or animal.

讓人更容易追蹤移動中的車輛或動物。

Yep, he's coming in across Central Park South right now.

他要通過中央公園南邊了。

Winner of this round...

這回合的贏家是...

Found ya.

找到你了。

Life360.

Life360。

Life360 and Google also show you the remaining battery percentage of the person you're tracking.

Life360 與 Google 也會告訴你對方剩下多少電量。

Sadly, Apple doesn't.

可惜，Apple 沒有這功能。

Test three: inside a building.

測試三，室內。

Yep, Aldo decided to go to work today.

沒錯，Aldo 今天決定去上班。

The GPS can get close and give you an idea of what indoor location someone is in.

全球定位系統能給你某人可能的室內位置。

But often it puts them right outside it on a map.

但通常，軟體會把他們標示在地圖上，該建築物的外面。

According to all three apps, he should be standing right here in the middle of 47th Street.

根據這三款應用程式，Aldo 應該要站在這裡，也就是 47 街的正中間。

Winner, none of them.

贏家？沒人。

They all plotted Aldo in the middle of the street.

它們都把 Aldo 標示在路邊。

Your decision should really come down to privacy policies and what phone you have.

你的最終決定應該取決於各公司的隱私政策，與你所持有的手機。

Apple's policies are the best.

Apple 有最好的隱私政策。

It retains your location data for just two hours.

它們只會保留你的位置訊息兩個小時。

Google, not so much.

Google 就沒那麼好了。

It requires that you enable a setting that let's Google keep a record of every place you've been.

它要求你允許 Google 記錄你去過的每個地方。

It can use this data to show you more targeted ads.

這可讓 Google 用來對你投放更多廣告。

Google does offer a tool to auto delete this data.

但 Google 有提供自動刪除這些資料的工具。

Life360's policy says your data could be used for advertising, and there's no way to currently delete your location data from it's servers.

Life360 的政策表示你的資料會被用作廣告用途，且目前沒有從它們伺服器刪除資料的方法。

If you've got friends and family with iPhones and Android phones go with Life360.

如果你有朋友或家人用 iPhone 或 Android 手機的，那就選 Life360。

I found it to be better and faster than Google Maps.

我發現它比 Google 地圖好用，也比較快。

If you've got an iPhone and friends and family with iPhones, go with Apple's Find My Friends.

如果你拿 iPhone，且你的朋友與家人也都用 iPhone，那就選 Apple 的尋找我的朋友。

Or what's going to be called, Find My in IOS 13.

或叫「尋找」，若你更新到 IOS 13。

I've decided to use Find My Friends with some of the closest people in my life.

我決定與好朋友使用「尋找我的朋友」。

Which basically now makes me Aldo.

這讓我變成了 Aldo。
