I built SwipeFlipper: snap a photo of a charity shop shelf, swipe to find what’s worth reselling (Flutter, need 8 beta testers)

Hi all, I’m Carl, a solo dev from the UK, and this is my first Android app. The problem: charity shops are full of DVDs, CDs, vinyl and games, but checking eBay one item at a time in the shop is slow and you look a bit odd doing it. What it does: Take one photo of a shelf and AI identifies every item on it, with an estimated resale price Swipe right to keep and left to skip, so you have a shopping list before you reach the till Track items from scanned to bought, listed and so

AI 分析

痛点:在二手店和慈善商店里逐件查 eBay 价格既慢又尴尬,缺少能一次识别整排货架商品并给出转售估价的工具。

目标用户:英国与欧美的 thrift/charity shop 淘货转卖者、eBay、Vinted、Depop 兼职卖家、副业翻卖者

证据:charity shops are full of DVDs, CDs, vinyl and games, but checking eBay one item at a time in the shop is slow and you look a bit odd doing it. / Feedback is welcome too, especially if the price estimates look off, or if you think there’s a better way to get pricing data than AI estimates.

变现:订阅制(每月 £3–6 无限扫描 + 真实成交价数据),或按扫描次数计费的积分包;也可做联盟导流,通过 eBay 联盟链接直接挂售并抽佣。

MVP:用 Flutter + 多模态视觉模型做整架拍照识别,接入 eBay Browse/Sold API 获取真实成交价区间而非让模型直接给出价格,本地 Hive 缓存离线可用,再做扫码、购物清单和利润看板。两周内可先只支持一个品类(如黑胶或 DVD)加一条商品数据源,验证识别准确率和成交价可信度。

竞品:Amazon Seller App(免费扫码看排名)、eBay App 条码扫描、Keepa、Scoutly、Bookscouter、Discogs(黑胶价格)、PicClick

摘要:英国独立开发者 Carl 做了 SwipeFlipper:拍一张慈善商店货架照片,用 OpenAI Vision 识别上面所有 DVD/CD/黑胶/游戏并估算转售价格,右滑保留左滑跳过,还能跟踪从购入到售出的利润。目前卡在 Google Play 要求 12 名测试者 14 天,而他只有 4 名,属于早期验证阶段,没有任何收入或付费证据。
