LetPod
祖孫接力小廣播 for iPhone · iPad
你一句 · 阿嬤一句 · 錄成一集
🛠 開發中 · 準備送審 App Store
孩子當「小老師」，抽一張任務卡先教阿公阿嬤一個英文單字，長輩再回教一句台語。你一句、我一句，麥克風精靈「小麥」在旁邊用童聲說現在換誰講、要講什麼——畫面上只有一顆大按鈕和一個大箭頭，六歲的孩子自己就能主持。按下完成，小麥當場把每一段剪好、音量拉齊、配上音效，變成一集只屬於這個家的小廣播。全部在裝置上完成，不上傳、不連網。完全免費、零廣告、不收集資料。
🔴 拿手機錄小孩，通常會遇到的三件事
| 會遇到 | ⛔ 一般錄音 app | 🎙 LetPod |
|---|
| 錄的時候 | 按下去就一直錄，沒人知道現在該誰講，最後變成一團模糊的背景音 | 回合制：一次只有一個人講、最長 30 秒，畫面永遠寫著「現在換誰」，錄完馬上一起聽 |
| 錄完之後 | 前後一大段空白、小孩太大聲阿嬤太小聲，沒人想聽第二次 | 按下完成自動剪掉頭尾靜音、把每一段音量拉齊、加上音效，變成一段聽得下去的節目 |
| 孩子的聲音 | 為了「AI 降噪」「自動剪輯」把小孩的原始錄音送上雲端 | 整個流程零網路：錄音、剪接、混音全在這台裝置，檔案要離開只有家長自己按分享 |
⚙️ 三個動作，錄完一集
1
抽一張任務卡
水果、動物、打招呼、呷飽沒——四個卡包各五題，抽到什麼就聊什麼，不會連續抽到同一題。
2
你一句、我一句
小麥說現在換誰講。一回合最長 30 秒，錄完自動放一次；不滿意就按「再一次」。
3
魔法後製
按下完成，小麥當場把整集剪好、音量拉齊、把你按過的音效混進去，收進作品架。
🔁 一題四段，這樣接力
③ 阿嬤出題
換阿嬤教台語：「林檎 lîn-gòo」。
一集預設兩題共八回合。台語目前在畫面上附羅馬拼音當提示；沒有評分、沒有紅色大叉，講錯了小麥也只會說「再試一次」。
✨ 功能特色
🎤
回合制接力錄音
一次只有一個人講，一回合最長 30 秒自動停。錄完立刻回放，想重來就按「再一次」——畫面上沒有「刪除」這種字。
🗂
四個任務卡包
水果、動物、打招呼、呷飽沒，各五題。每題都是「孩子教英文 → 長輩回教台語」的四段接力，不用自己想話題。
🟣
小麥全程帶
戴耳機的麥克風精靈，用放慢的國語童聲說現在換誰講；等孩子時拉大耳朵、等阿嬤時看向畫面外，不識字也跟得上。
🔔
三顆罐頭音效
叮咚、拍手、彈簧「咚～」。錄音中隨時可以按，會混進那一回合——把小孩最愛的「出怪聲」變成節目的一部分。
✨
裝置端魔法後製
剪掉每段頭尾靜音、把小聲的講話拉到跟大聲的一樣、混入音效與間隔，輸出成一個 m4a。不上傳、不連網、不用任何雲端服務。
📚
作品架與回收箱
做好的節目留在作品架上隨時再聽，最多 20 集。孩子放進回收箱的節目，大人 7 天內都可以救回來。
👨👩👧 給家長
- 錄音只存在這台裝置的 app 空間裡，不上傳、不做語音辨識、不經任何雲端；只有你在家長區按下分享，檔案才會離開。
- 家長區在首頁右上角的鎖，由乘法題或 4 位數密碼把關；分享清單、儲存空間、回收箱、語言、家族貨架都在裡面。
- 小麥的聲音是 Apple 系統語音在裝置上即時合成的，沒有下載、沒有傳送任何音訊。
- 唯一的內購是家長區裡三檔自由讚助（請開發者喝咖啡），由 Apple 處理、不解鎖任何功能，也不會出現在孩子的畫面上。
- App 沒有帳號、沒有伺服器、沒有分析、沒有廣告，App 隱私標示為「未收集資料」。

Podcast with Grandma · iPhone · iPad
You say one · Grandma says one · It's a show
🛠 In development · Preparing for App Store review
A child plays the "Little Teacher": draw a task card, teach Grandma or Grandpa a word in English, and let them teach one back in Taiwanese. One line each, back and forth, while Bite — the microphone mascot — says whose turn it is in a friendly child's voice. One big button, one big arrow: a six-year-old can host the whole show. Tap done and Bite trims every take, evens out the volumes, adds the sound effects, and turns it into one little family radio episode — all on the device, with no upload and no internet. Completely free, ad-free, no data collected.
No AdsNo third-party SDKs
No DataRecordings stay on device
No CloudMixing happens on-device
🔴 What usually happens when you record a child
| What you hit | ⛔ A plain voice recorder | 🎙 LetPod |
|---|
| While recording | One long take where nobody knows whose turn it is — it ends up a blur of background noise | Turn by turn: one person at a time, 30 seconds max, the screen always says who's up, and every take plays back right away |
| Afterwards | Dead air at both ends, the child shouting and Grandma barely audible — nobody plays it twice | Tap done and it trims the silence, evens out every take and adds sound effects, into something you actually want to hear again |
| Your child's voice | Sent to the cloud for "AI noise removal" and "automatic editing" | Zero network end to end: recording, trimming and mixing all happen on this device — a file leaves only when a grown-up taps Share |
⚙️ Three steps to a finished episode
1
Draw a task card
Fruits, animals, greetings, everyday Taiwanese — four packs of five, and it won't hand you the same one twice in a row.
2
Take turns
Bite says who's up. Each turn is 30 seconds at most and plays back automatically; tap "Again" to redo it.
3
Magic mixing
Tap done and Bite trims, balances and mixes in the sounds you tapped, then files the episode on the shelf.
🔁 One card, four turns
1. Little Teacher
Teaches the English word: "Apple!"
2. Grandma repeats
Says the English word after the child.
3. Grandma teaches
Her turn: the Taiwanese word, "lîn-gòo".
4. Little Teacher repeats
The child says it back after Grandma.
An episode is two cards — eight turns. Taiwanese words show their romanization on screen as a hint. Nothing is scored and there is no red X: if it comes out wrong, Bite just says "let's try that again".
✨ Features
🎤
Turn-by-turn recording
One speaker at a time, stopping automatically at 30 seconds. Every take plays back immediately and can be redone — the child's screen never says "delete".
🗂
Four task-card packs
Fruits, animals, greetings and everyday Taiwanese, five cards each. Every card is the same four-turn relay, so nobody has to invent a topic.
🟣
Bite guides every turn
A microphone mascot in headphones speaks slowly in a child's voice; it stretches its ears while waiting for the child and looks off-screen for Grandma. No reading required.
🔔
Three sound effects
A ding, a clap and a boing, tappable mid-recording and mixed into that turn — turning "making silly noises" into part of the show.
✨
On-device magic mixing
Trims the silence from each take, lifts the quiet voices to match the loud ones, mixes in the effects and spacing, and writes one m4a. No upload, no internet, no cloud service.
📚
Shelf and recycle bin
Finished shows stay on the shelf to replay, up to 20 of them. Anything the child drops in the recycle bin can be restored by a grown-up for 7 days.
👨👩👧 For grown-ups
- Recordings stay only on this device, inside the app's own storage. Nothing is uploaded, nothing is transcribed, no cloud is involved — a file leaves only when you tap Share in the grown-ups' area.
- That area sits behind the lock in the top-right corner, protected by a multiplication question or a 4-digit passcode. Sharing, storage usage, the recycle bin, language and the family shelf all live there.
- Bite's voice is synthesized on the device by Apple's system speech — no audio is downloaded or transmitted.
- The only in-app purchases are three optional tips (buy the developer a coffee) behind that gate, handled by Apple. They unlock nothing and never appear in the child's flow.
- No account, no server, no analytics, no advertising. App privacy: Data Not Collected.

🗺 Progress
✓
Project skeleton Done
iOS project, bilingual catalogs, privacy manifest, plus automated guards for "zero network" and "no third-party SDKs".
✓
Relay state machine & cards Done
A pure-logic relay machine (redo, interruption, no repeated draws) and the content structure for four packs of five cards with Bite's lines.
✓
Recording, Bite & sound effects Done
Turns that stop at 30 seconds, automatic playback, six hand-drawn-in-code mascot poses, and three canned effects mixed in live.
✓
Mixing, shelf & grown-ups' area Done
On-device trim / balance / mix export, a 20-episode shelf with a 7-day recycle bin, sharing and the family shelf behind the gate. A full episode already records end to end on iPad.
▶
Taiwanese content & submission prep In progress
Finalising the 20 Taiwanese words, on-device microphone-distance testing, and the App Store submission material and screenshots. The first archive already passes Xcode validation — logged on the App Store Journey.
…
Grandma's help button & music Later
Let a grown-up pre-record a Taiwanese hint for each card — press for help and you hear your own family's voice — plus baking Bite's narration into the episode and a light backing track.
🎙 LetPod is in development
Keep Grandma's words in your child's voice. The App Store link will appear here once it launches — completely free, ad-free, no data collected, fully offline.
