Free to install is not free to use
Many apps are free to download but place core features behind in-app purchases. Before installing, look for IAP markers, subscription plans, and trial language. If the store page is vague, assume the useful version may cost more than the download price.
免费安装不等于免费使用
很多应用可免费下载，但核心功能依赖内购。安装前查看内购标记、订阅方案和试用文案。如果商店页表述模糊，应默认真正好用的版本可能比下载价更贵。
Know the main IAP types
Common models include one-time unlocks, consumable credits, auto-renewing subscriptions, and non-renewing subscriptions. One-time unlocks are usually easiest to reason about. Consumables and auto-renewing plans need more caution because spending can continue after the first purchase.
先分清主要内购类型
常见模式包括一次性解锁、消耗型点数、自动续订订阅和非续订订阅。一次性解锁通常最好理解。消耗型和自动续订需要更谨慎，因为首购之后仍可能持续花钱。
Inspect trial conversion risk
A free trial is useful only if you know the end date, renewal price, and cancellation path. Set a reminder one day before renewal. Do not rely on deleting the app. Cancellation lives in Apple ID subscription settings, not on the home screen.
检查试用转正风险
免费试用只有在你清楚结束日期、续费价格和取消路径时才安全。续费前一天设置提醒。不要依赖删除应用来停止扣费；取消入口在 Apple ID 订阅设置，不在主屏幕。
Read what the base price actually includes
Some paid apps still require subscriptions for cloud sync, export, advanced filters, or multi-device access. Compare the base purchase with the recurring plan. A slightly higher one-time price can be better value than a low entry price with expensive renewals.
看清本体价格真正包含什么
有些付费应用仍需要订阅才能云同步、导出、使用高级滤镜或多设备访问。把本体购买和周期订阅一起比较。略高的一次性价格，有时比低门槛但高续费的方案更划算。
Use lookup tools without over-trusting them
Storewise can help surface public IAP signals and regional differences, but Apple page structures and regional catalogs change. A failed lookup does not prove that no IAP exists. Always confirm the final offer sheet in the App Store before paying.
使用查询工具，但不要过度信任
研究工具 可以帮助展示公开内购信号和地区差异，但 Apple 页面结构和地区目录会变化。查询失败不代表没有内购。付款前仍要以 App Store 最终报价页为准。
Decision rule before installing
Install only after you can answer: What is free? What is one-time? What renews? Can I cancel easily? Is Family Sharing supported? If any answer is unclear, open the checklist page and delay payment until the plan is understandable.
安装前的判断规则
只有在你能回答这些问题后再安装：哪些免费？哪些一次性？哪些会续费？能否方便取消？是否支持家庭共享？如果任何一项不清楚，先打开清单页，等方案清楚后再付款。
Types of IAP and how they fail
Consumables can be spent and re-bought; non-consumables should unlock permanently; subscriptions recur; non-renewing subscriptions expire without auto-renew. Failures include missing restore buttons, unlocks tied to the wrong Apple ID, and consumables that never credit after a network drop. Always use Restore Purchases on a second device before rebuying a non-consumable. For consumables, screenshot the balance before and after purchase.
内购类型与常见失败方式
消耗型可花完再买；非消耗型应永久解锁；订阅会循环；非续期订阅到期不自动续。失败包括缺少恢复按钮、解锁绑错 Apple ID、断网后消耗品不到账。第二台设备重买非消耗型前先点恢复购买。消耗型购买前后截图余额。
Family Sharing and IAP limits
Not all IAP are shareable. Subscriptions may share only if the developer enabled Family Sharing. Consumables almost never share. Before buying for a household, check the product page share status and test on a family member device after purchase. If a child can buy consumables freely, enable Ask to Buy and set app limits. Educate kids that in-game buttons can be real money even when the app was free to download.
家庭共享与内购限制
并非所有内购可共享。订阅仅在开发者启用家庭共享时可能共享。消耗型几乎从不共享。为家庭购买前检查产品页共享状态，购后在家庭成员设备测试。若孩子可自由买消耗品，启用购买前询问并设应用限制。教育孩子：即使应用免费下载，游戏内按钮也可能花真钱。
Restore, refund, and support sequence
First restore purchases on the same Apple ID. Second, force-quit and retry on Wi-Fi. Third, check Purchase History for the charge. Only then contact the developer or file Report a Problem. Rebuying immediately often creates two charges instead of one fix. Keep a short log of times and error messages so support is not a vague complaint.
恢复、退款与支持的顺序
先在同一 Apple ID 上恢复购买。其次在 Wi-Fi 下强制退出重试。第三检查购买记录是否扣费。之后再联系开发者或 Report a Problem。立刻重买常造成两笔扣费而非一次修复。记录时间与错误信息，避免支持变成模糊抱怨。
Five IAP buckets on one sticky note
Label every item as: one-time unlock, consumable, auto-renew subscription, non-renewing subscription, or unclear. Unclear means do not buy yet. Consumables disappear when spent; unlocks should persist on the same Apple ID; subscriptions need cancel paths. This sticky note prevents mixing a tip jar with a weekly trap.
一张便签上的五类内购
把每项标成：一次解锁、消耗型、自动续订、非续订订阅、或不清。不清就先别买。消耗型用完即无；解锁应在同一 Apple ID 保留；订阅需要取消路径。这张便签避免把打赏和周付陷阱混为一谈。
Trial math before Start
Convert post-trial price to monthly and yearly. Write the first charge date on a calendar with a cancel reminder two days earlier when possible. If the app hides the post-trial price until after Sign in with Apple, treat that as a quality signal and slow down. Pair this with the trial reminder tool on a research helper.
点开始前的试用数学
把试用后价格换算成月与年。在日历写首次扣费日，并尽量提前两天设取消提醒。若应用要登录后才显示试用后价格，视为质量信号并放慢。配合 研究工具 试用提醒工具。
Restore purchases and Family Sharing limits
Know whether Restore Purchases exists and whether Family Sharing applies. Consumable packs usually do not share. After any buy, verify the entitlement on a second device signed into the same Apple ID when the purchase is expensive. Keep the receipt email or Purchase History line for support.
恢复购买与家庭共享限制
确认是否有恢复购买、是否适用家庭共享。消耗包通常不共享。高价购买后，在登录同一 Apple ID 的第二台设备验证权益。保留收据邮件或购买记录行以便支持。
SKU naming tricks to decode
Weekly plans named pro, continue, or unlock need the full IAP list sorted by period. If two SKUs buy one job, keep the lower annualized cost.
拆解 SKU 命名花招
叫 pro、continue、unlock 的周付要打开完整内购并按周期排序。两个 SKU 同一用途时留年化更低者。
Map every SKU to a one-line job
Before install or Start Trial, open the full IAP list and write one job per SKU: unlock export, remove ads, add seats, or sell consumable coins. If two SKUs buy the same job, keep the lower annualized option. If a SKU has no job you can name, treat it as a future trap even when the base app is free. Store the map with a screenshot of the offer sheet. Households that skip the map argue later about mystery Pro lines in Purchase History. Public lookup tools can speed scanning, but your confirm sheet remains the contract.
把每个 SKU 映射成一句话用途
安装或开始试用前，打开完整内购列表，为每个 SKU 写一句话用途：解锁导出、去广告、加席位，或卖消耗币。若两个 SKU 买同一用途，留年化更低者。若 SKU 说不出用途，即使本体免费也当未来陷阱。地图与报价页截图放一起。跳过映射的家庭稍后会为购买记录里神秘 Pro 行争吵。公开查询工具能加速扫描，但确认页仍是合约。
Case: free editor, weekly Pro, export hostage
A free photo editor installs cleanly, then gates export behind Pro Weekly after a three-day trial. The user thinks cancel later, forgets, and pays roughly five hundred a year for a job a one-time unlock elsewhere might cover. Recovery: cancel in Subscriptions, export anything still available, screenshot history, and write the brand on a ninety-day avoid list. Prevention: annualize before Start, refuse paywalls that hostage files, and prefer tools that export on free tier after cancel. File Report a Problem only with evidence if the charge is App Store billed and within a sensible window.
案例：免费编辑器、周付 Pro、导出挟持
免费照片编辑器安装顺利，三天试用后把导出锁进 Pro Weekly。用户想着稍后取消，忘记了，一年约五百只为别处一次解锁可能覆盖的用途。恢复：在订阅取消、导出仍可得内容、截历史，品牌写入 90 天避开名单。预防：开始前年化、拒绝挟持文件的付费墙、优先取消后免费档仍可导出的工具。仅当 App Store 计费且时机合理时带证据 Report a Problem。
Trial math before Start, not after the charge
Write trial length, first charge date, post-trial price, period, and annualized cost if forgotten. Three free days into 9.99 weekly is roughly 520 yearly before tax. Set a calendar alert for tomorrow morning on short trials. Shared devices need organizer visibility the same day a trial starts. If the offer sheet hides post-trial price until after Sign in with Apple, slow down—that opacity is a product choice. Cancel path must be two taps from Settings, not a scavenger hunt inside the app.
在开始前算试用账，而不是扣费后
写试用时长、首次扣费日、试用后价格、周期，以及忘记取消时的年化。三天免费接 9.99 周付，税前年化约 520。短试用把日历提醒设明天早上。共用设备上试用开始当天组织者要可见。若报价页要登录后才显示试用后价格，放慢——不透明是产品选择。取消路径须从设置两步可达，不是应用内寻宝。
Family Sharing limits you should assume
Do not assume every IAP shares. Consumables usually do not. Some subscriptions share seats only under specific plans. Child free installs can still open non-shared IAP funnels if purchase gates are weak. Document which plans are shared, who the owner adult is, and how cancel works for the organizer. Ownerless shared plans become ghosts on the paying card.
应默认假设的家庭共享限制
不要假设每个内购都共享。消耗型通常不共享。部分订阅仅在特定方案下共享席位。若购买闸门弱，儿童免费安装仍可打开不共享的内购漏斗。写明哪些方案共享、负责成人是谁、组织者如何取消。无主共享方案会在付款卡上变幽灵。
Exit condition: one map, one alert, one control
You are done when the SKU-to-job map exists, a cancel alert is scheduled if a trial started, and shared devices have a purchase control that matches policy. Reading IAP definitions without those three is incomplete. Put artifacts in an adult note. If money already moved, match bank to Purchase History within twenty-four hours and choose the correct desk.
退出条件：一张图、一个提醒、一项控制
当 SKU-用途图存在、若已开试用则已设取消提醒、共用设备购买控制匹配政策时才算完成。只读内购定义没有这三样就不完整。工件放进成人笔记。若已扣费，二十四小时内把银行对齐购买记录并选对柜台。
One-page field card
Compress into one page: goal, Apple ID identity, device, money or permission at stake, action today, verification tomorrow, control change this week. Screenshot into an adult note. If you cannot fill the card, you are reading ahead of acting. Share with the household payer when money is involved. Revisit in seven days and mark kept, cancelled, or escalated.
一页现场卡
压成一页：目标、Apple ID 身份、设备、金钱或权限、今天动作、明天验证、本周控制变化。截图进成人笔记。填不满说明读得比做得快。涉及金钱与付款人共享。七天后标记保留、取消或升级。
Consumables versus unlocks: restore expectations
Consumable coins and packs usually will not restore after reinstall and often will not Family Share. One-time unlocks should restore on the same Apple ID via Restore Purchases. Auto-renew subscriptions restore by signing into the paying identity and opening Subscriptions. Mixing these expectations creates false refund fights. Write the type on your sticky note before the prompt so you know what recovery looks like if the device changes.
消耗型与解锁：恢复预期
消耗型金币与礼包重装后通常不可恢复，也常不支持家庭共享。一次解锁应在同一 Apple ID 上通过恢复购买找回。自动续订通过登录付款身份并打开订阅恢复。混淆这些预期会制造虚假退款争执。提示前在便利贴写类型，以便换设备时知道恢复长什么样。
Introductory pricing that expires into a different SKU
Some offers start as intro monthly then convert to a higher weekly or multi-tier Pro. Read the fine print on the confirm sheet for what happens after intro. Write the post-intro annualized cost, not only the intro month. Calendar the intro end date separately from the first trial cancel date when both exist. Households that only calendar trial end miss intro cliffs.
到期后变成另一 SKU 的首期价
有些优惠以首期月付开始，随后转成更高周付或多档 Pro。在确认页读首期后发生什么。写下首期结束后的年化，而不只是首月。若试用取消日与首期结束日都存在，分开设日历。只日历试用结束日的家庭会错过首期悬崖。
Offline usefulness after cancel
If the job must work offline after you cancel, test export and offline access during the trial. Paywalls that appear only after cancel are hostages. Prefer tools that keep basic export on free tier. Write offline need as a yes/no on the SKU map. A keep decision that fails offline need is incomplete.
取消后的离线有用性
若取消后用途必须离线可用，试用期内测试导出与离线访问。只在取消后出现的付费墙是挟持。优先免费档仍保留基础导出的工具。在 SKU 图上把离线需求写成是否。不能满足离线需求的保留决策不完整。
Child-visible paywalls and purchase gates
On shared devices, IAP paywalls can appear to children even when Ask to Buy is on for paid asks. Free downloads still need gates. After any child-facing install with IAP, run the same-day Subscriptions check as the organizer. Education about gems without gates fails; gates without education create workarounds. Document both.
儿童可见的付费墙与购买闸门
共用设备上，即使付费请求有购买前询问，儿童仍可能看到内购付费墙。免费下载仍要闸门。任何面向儿童且含内购的安装后，组织者当天查订阅。没有闸门的宝石教育会失败；没有教育的闸门会催生绕过。两者都记录。
Seven-day verification after you decide
Verify on a schedule: same day for cancels and permission changes, seven days for installs and trials, thirty days for family policy. Each loop checks one artifact. Missing artifact means incomplete action. Put the next date in the same note as the decision and share it when Family Sharing money is involved.
决策后的七日验证
按计划验证：取消与权限变更看当天，安装与试用看七天，家庭策略看三十天。每次只核一份工件。工件缺失=动作未完成。把下一日期写在与决策同一笔记，家庭共享涉及金钱时共享。
Artifact checklist when you finish
Leave with at most three artifacts: one screenshot or table, one calendar date, one control or inventory change. More becomes clutter. Store them in an adult note. If you cannot name the three, you are not done. This checklist is the operational exit condition for the guide.
完成时的工件清单
最多带走三份工件：一张截图或表、一个日历日、一项控制或台账变化。更多会变杂物。放进成人笔记。说不出三份就还没做完。此清单是本指南的运营退出条件。
Annualize before emotion does the math
Create a one-column list converting every weekly plan to yearly before keep decisions. Humans under-react to small weekly numbers. If annualized total exceeds your written cap, cancel until under. Post the list during Sunday triage. Unsentimental math is a feature.
在情绪算账前先年化
保留决策前把每个周付换成年列在一栏。人类低估小周价。若年化超过书面上限，取消到低于上限。周日分诊时贴出。不煽情的数学是优点。
Support path cheat sheet for IAP problems
Restore purchases for missing unlocks on same Apple ID. Cancel first for unwanted renewals. Report a Problem for App Store billed refunds with evidence. Developer support for product bugs. Bank only for clear non-Apple fraud after identity is confirmed. Wrong order wastes days.
内购问题的支持路径速查
同 Apple ID 丢失解锁走恢复购买。不想要的续费先取消。App Store 计费退款带证据 Report a Problem。产品 bug 找开发者。明确非 Apple 欺诈且身份确认后才银行。顺序错误浪费数天。
Owner adult and next verification date
Write the next verification date beside today’s decision and name the owner adult if Family Sharing money is involved. One artifact beats five chats. If you cannot point to the artifact next week, reopen the guide and finish the exit condition. This note exists only to complete operational depth without repeating industrial templates.
负责成人与下次验证日
把下一次验证日写在今天决策旁；若涉及家庭共享金钱，写负责成人。一份工件胜过五条聊天。若下周指不出工件，重开指南完成退出条件。本段仅用于补足运营深度，不重复工业模板。
