Looking for iOS beta testers for a privacy-first personal data-tracking app (Datum)
Hi all, long-time lurker here. Been developing apps since 2008. Recently laid off and decided to build an app that’s been on my mind for 13 years. The app was mainly to scratch my own itch: tracking arbitrary things over time without handing my data to anyone - but with style.
The idea is simple. You define your own categories with real units (kg, mL, °C, count, currency, %, or freeform), log numbers against them, then filter, chart, and export to CSV or JSON. It syncs across your own devices through your private iCloud - **no account, no server, nothing leaves your device except your own iCloud.** I can't see your data, and there's nothing to log into.
It's still early and I'm sure there are rough edges, which is exactly why I'm here. If a few of you would be willing to kick the tires and tell me what's missing, broken or annoying, I'd be genuinely grateful. Totally understand if it's not your thing.
