计时与休息

Timing and rest

倒计时支持 1–180 分钟，也可正计时。暂停不累计专注时长；完成后保存记录，可手动开始休息。

Choose a 1–180 minute countdown or a stopwatch. Paused time is excluded; completed sessions are saved and a rest can be started manually.

12 种真实录音环境声

12 real ambient recordings

14 个场景包含书亭、雨天窗边、壁炉书房、茶室等。10 个新场景入夜后换成夜景，本地时间 19:00 开始、次日 06:00 换回日景。12 种真实录音环境声来自 Freesound 的 CC0 公有领域作品，包含风、溪流、鸟鸣、雨、篝火、海浪等；免费版提供 5 种声音，最多混合 3 轨；完整版提供 12 种声音、不限混合，并可保存声音配方。每轨音量可单独调整。

Choose from 14 scenes, including a pavilion, rainy window seat, fireside study and tea room. The 10 new scenes show night artwork from 19:00 until 06:00 local time. The 12 real ambient recordings come from Freesound CC0 public-domain works, including wind, streams, birds, rain, fire and waves. The free version includes five sounds and up to three simultaneous tracks. Full access includes unrestricted mixing of 12 sounds and saved sound recipes. Each track has its own volume.

历史与统计

History and statistics

搜索、补记或修正专注记录，查看周统计。月度统计与月内标签分布属于付费权益。

Search, add or edit focus records and view weekly statistics. Monthly statistics and the monthly tag breakdown require paid access.

声音可在后台播放

Background audio

开启环境声后可在切到后台或锁屏时播放；来电和其他音频可能打断。计时按时间戳恢复，不依赖后台每秒刷新。

Enabled ambient audio can play in the background or while locked. Calls or other audio can interrupt it. Timer recovery uses timestamps, not a constantly running background tick.

CSV 与 ZIP 备份

CSV and ZIP backups

CSV 用于查看记录，ZIP 保存完整记录与偏好。导入前预览，重复编号保留本机版本。基础导出免费。

Use CSV for readable records and ZIP for full records and preferences. Preview imports first; duplicate IDs keep the local version. Basic export is free.

按需提醒，本机保存

Optional reminders, local records

不要求账号，不提供应用内云同步。只有主动开启结束提醒时请求本地通知权限。

No app account or in-app cloud sync. Local notification permission is requested only when end reminders are enabled.

会员、购买与恢复

中国大陆常规定价为完整版月付 ¥8／1 个月、年付 ¥28／1 年、永久版 ¥39／一次。月付与年付在同一订阅组内自动续费，提供相同权益；永久版为非消耗型购买，不自动续费。实际币种、价格及活动优惠以购买时的商店确认页为准。免费版有 5 种声音、最多同时混合 3 种；完整版解锁全部场景、12 种声音不限混合、声音配方和月度统计。

iOS 购买由 Apple App Store 和 StoreKit 处理；鸿蒙购买由华为应用内支付处理，并在设备上校验签名购买凭证。应用无需注册账号，没有自建业务后端；应用不会另行把购买凭证发送给开发者服务器。购买、恢复、管理订阅和打开协议链接需要联网。苹果与华为的购买独立，不能跨商店恢复。

换机或重装后，在同一商店登录原购买账号，再从“设置 → 完整版”选择“恢复购买”。恢复有效权益不重复收费，也不会恢复本机专注记录；记录请使用自行导出的备份。

iOS 在“设置 → 你的姓名 → 订阅”取消；鸿蒙在“设置 → 华为账号 → 付款与账单 → 订阅”取消。卸载应用或购买永久版不会替你取消已有订阅。取消后，当前已付费期间仍可使用。详见自动续费服务协议与隐私政策；iOS 使用 Apple 标准 EULA，鸿蒙使用鸿蒙版使用条款。

Membership, purchases and restoration

Regular mainland China prices are CNY ¥8 for one month, ¥28 for one year, and ¥39 for lifetime access. Monthly and yearly plans auto-renew in one subscription group and provide the same benefits. Lifetime is a non-consumable purchase without renewal. The store confirmation at purchase shows the actual local currency, price and any promotion. The free version includes five sounds and up to three simultaneous tracks. Full access unlocks all scenes, unrestricted mixing of 12 sounds, sound recipes and monthly statistics.

Apple App Store and StoreKit handle iOS purchases; Huawei In-App Purchases handles HarmonyOS purchases, with signed purchase data verified on the device. No app account or developer-operated backend is used. The app does not separately send purchase receipts to the developer. Purchases, restoration, subscription management and policy links need a network connection. Apple and Huawei purchases are separate and cannot be restored across stores.

After reinstalling or changing devices, sign in to the original account in the same store, then choose Restore Purchases in Settings → Full version. Restoring valid access does not charge again or recover local focus records. Use your exported backups for records.

On iOS, cancel in Settings → your name → Subscriptions. On HarmonyOS, use Settings → HUAWEI ID → Payments and purchases → Subscriptions. Uninstalling or purchasing lifetime access does not cancel an existing subscription. Access continues for the paid period after cancellation. See the Auto-Renewal Agreement and Privacy Policy. Apple’s Standard EULA applies on iOS; see the HarmonyOS terms for that version.
