Original Summary

I'm building Lumina, an iPhone app for the record-keeping around shooting film: unused rolls, camera gear, what's loaded, exposure notes and rolls waiting on the lab. It's now on the App Store. The main product decision was to connect those records to a light meter instead of making five separate lists. The flow is: add a camera, load a roll in the app, meter at that roll's rated ISO, then save the reading to the roll and frame. It's a manual companion to a film camera, not automatic frame detection. Two constraints shaped it: - On-device storage. No account, tracking or server; local backup and CSV export instead of cloud sync. The tradeoff is that users need to make backups before switching phones. - Free permanently. I originally considered a paid-download model, but decided to keep the whole app free. No ads, in-app purchases or subscription. I'm not presenting this as a revenue success story. It's native Swift, built with AI coding assistance. There are no generative-AI features in the app. The product question I'm working on now is first use: should an app like this start with adding one camera and its loaded roll, or let people catalogue their film first? I'd appreciate feedback on which makes the value clearer without a long setup. Requires iPhone with iOS 17 or later: https://apps.apple.com/ca/app/lumina-film-light-meter/id6758922305   submitted by   /u/FriendshipFamiliar83 [link]   [comments]

中文标题： 我为胶片摄影师开发原生 Swift 应用，并决定保持免费

作者开发了 Lumina，一款用于胶片摄影记录的 iPhone 应用，已上架 App Store。核心是把胶卷、相机、测光等记录连接起来，而非做成多个独立列表。流程为添加相机、装入胶卷、按额定 ISO 测光，并保存读数。应用仅本地存储，无账户、追踪或服务器，支持本地备份和 CSV 导出；永久免费，无广告、内购或订阅。使用原生 Swift，AI 辅助编码，无生成式 AI 功能。当前在思考首次使用应先添加相机和胶卷，还是先编目胶片。需要 iOS 17 或更高版本。
