lindly vs Nara Baby Tracker
The short answer
Nara Baby Tracker (formerly “Baby Tracker”) is genuinely free, ad-free, and offers simple full-access family sharing — a strong, honest free option. lindly differs on data residency (Switzerland versus the United States), gives you both CSV and JSON export, works offline, and lets your own AI assistant read and log over MCP. Pick Nara for “completely free, forever”; pick lindly for Swiss hosting, offline-first sync, and openness.

Where lindly is different
- Data hosted in Switzerland (Zurich) rather than the United States.
- Offline-first logging, and both CSV and JSON export (Nara offers CSV only, and doesn't publish offline behavior).
- Connect your own AI assistant over MCP — Nara publishes no AI or API access.
Where Nara Baby Tracker is ahead — honestly
- Completely free with no premium tier and no ads — funded by a separate formula business.
- A mature, available-today app with a broad logging set (pumping, solids, medications, growth) out of the box.
- Its app-store Data Safety label declares no third-party data sharing.
Common questions
- Is Nara Baby Tracker really free?
- Yes — Nara states the app is completely free, with no premium tier, no ads and no in-app purchases, funded by its parent company's formula business (as of 2026-07). lindly has a free tier too, plus a Premium tier priced at launch.
- Where does each app store your data?
- lindly hosts all family data in Switzerland (Zurich, europe-west6). Nara's privacy policy states its services are hosted and operated in the United States, with possible transfer to other countries (as of 2026-07).
- Does Nara share or sell your data?
- It's nuanced, so we cite both sources: Nara's Google Play Data Safety label says the app shares no data with third parties, while its website privacy policy says it does not “sell” data for money but that its advertising / retargeting cookies “may be deemed a sale or a share” under some US state laws (as of 2026-07). lindly shares nothing.
- Can I export everything, in both CSV and JSON?
- With lindly, yes — full history as CSV and JSON, free on every tier. Nara offers a free CSV export but not JSON (as of 2026-07).
