Sunny Seed

Most baby trackers are a spreadsheet with a nicer UI. Sunny Seed differs in two ways. Privacy by architecture: WHO percentiles are computed on-device, so measurements never leave the phone. Photo tagging runs locally on Apple Vision, voice input is on-device, audio is never stored. The rest stays in the EU. And the data becomes something you keep: at month's end your notes turn into a letter about that month - not a chart, but text you'll reread in five years. Six languages, incl. Arabic RTL.
