AI 分析

痛点:出国购物时货架标价需要现场换算成本币,且标签上常同时出现单价与总价、货币符号含义模糊,游客难以快速判断“这到底贵不贵”。

目标用户:出国旅行/出差、需要在超市或商场现场比价的购物者,尤其是网络信号差的境外场景用户。

证据:It is free with ads and a limited number of scans; there is an optional one-time Pro purchase. / Holding the camera on the same label should count as one scan, not a new scan on every frame.

变现:免费版带广告+扫描次数限制,Pro 一次性买断解锁无限扫描与历史记录;后续可扩展到多币种汇率包、离线汇率更新订阅。

MVP:2 周 MVP:用 ML Kit / Tesseract 做货架标价 OCR,识别总价与单价并高亮,配合本地缓存的汇率做离线换算,加一个“点按确认才保存”的防误判交互和历史记录列表。

竞品:Google Lens、XE Currency、Currency Converter Plus、Revolut 汇率换算

摘要:开发者自述用 Android 侧项目 PriceBuddy 解决境外购物时货架标价的换算与单价/总价辨识问题,支持相机识别、离线汇率和手动换算,已在 Google Play 上架。变现方式是广告+扫描次数限制,外加可选的一次性 Pro 买断,但帖中没有任何收入或用户付费数据,需求验证程度低;同类通用汇率换算竞品众多,差异化空间主要在离线可用和货架标签识别精度。
