Walk the way you always do. Later, open Trail Letters: your steps carry a traveler along a quiet island shore, delivering letters for the lighthouse keeper and bringing home keepsakes for your camp.
iPhone · iOS 17 or later · English, 简体中文 · Early preview — artwork is temporary

No workouts to start, no streaks to keep. Just your day, and a story that moves with it.
Trail Letters uses the steps your iPhone already counts. Nothing to start or track — and you never need to look at your phone while walking.
Open the app when you like. Your new steps carry you toward the next place on the shore, where a letter is waiting.
Each letter leaves a keepsake. Place them around your camp and watch it slowly become yours.



Short letters, small choices, a camp that grows — and no pressure.
Help Marigold, the lighthouse keeper, and Tobin at the post office untangle the island's mail, one letter at a time.
A path of places along the shore shows where you've been and how far it is to the next stop.
Some letters ask you to decide — peek at a note or keep it sealed. Choices change the words, never take anything away.
A wooden post sign, a blue glass bottle, an old stamp… arrange them in your camp however you like.
Prefer not to share motion data, or your device can't count steps? Read every letter and decorate your camp anyway.
Nothing is lost if you don't walk. Unused steps wait for you, and your traveler never gets punished.
Steps count from the moment you begin your journey. Opening the app twice never counts the same steps twice.
Turn your camp or a favourite letter into a postcard to send to friends. Postcards never show your steps, dates or location.
Optionally compare with your Game Center friends — by letters delivered on foot each week, never by raw step counts.
Built with Dynamic Type, VoiceOver labels and Reduce Motion in mind, in light and dark mode.
Trail Letters is being tested on TestFlight right now.
Trail Letters has no account and doesn't send your data anywhere.
Read the privacy policy照常走路就好。之后打开岛屿来信:你的步数会带着旅行者沿着一片安静的海岸,帮灯塔管理员送信,把纪念物带回你的营地。
iPhone · iOS 17 及以上 · English、简体中文 · 早期预览版,美术为临时图

不用开始运动,不用守连续打卡。过你自己的一天,故事跟着往前走。
岛屿来信用的是 iPhone 本来就在记录的步数。不用按开始,也不用边走边看手机。
想看的时候打开 App。新的步数会带你走向海岸上的下一站,那里有一封信在等你。
每封信都会留下一件纪念物。把它们摆在营地里,营地会慢慢变成你自己的样子。



短短的信、小小的选择、慢慢长大的营地——没有压力。
帮灯塔管理员玛丽戈德和邮局的托宾,一封一封理清岛上乱成一团的邮件。
海岸上的一串地点,告诉你走过了哪里、离下一站还有多远。
有些信会请你做决定:偷看一眼字条,还是保持封好。选择只改变故事的文字,不会让你失去任何东西。
木制邮牌、蓝色玻璃瓶、旧邮票……随你喜欢摆在营地里。
不想提供运动数据,或者设备不能计步?照样可以读每一封信、布置营地。
不走路不会失去任何东西。没用完的步数会留着,旅行者也不会被惩罚。
从开启旅程那一刻开始累计。打开两次 App,同样的步数绝不会算两次。
把营地或喜欢的一封信做成明信片发给朋友。明信片不会显示步数、日期或位置。
可以选择和 Game Center 好友比一比——比的是每周走着送到的信,不是步数。
按动态字体、VoiceOver 朗读和减少动态效果来设计,支持深浅色模式。
岛屿来信目前正在 TestFlight 上测试。
