### 5/5 — La app que toda mamá necesita 💕

*2026-05-06*

Soy mamá hace poquito y practico lactancia diferida. Antes anotaba extracciones, pañales y horarios en notas sueltas del celular — era un caos. Esta app me organizó la vida en serio.

Lo que más uso:
•⁠  ⁠El tracker de extracciones con lado y cantidad (clave para mantener la producción pareja)
•⁠  ⁠El widget en pantalla — de un vistazo sé cuándo toca la próxima

Sin publicidad, sin distracciones, súper intuitiva. Hecha por alguien que entendió de verdad lo que necesitamos las mamás. 5 estrellas sin pensarlo.

## Version history (last 3 releases)

### 3.5.13 — 2026-05-12

Critical fix: app no longer crashes on launch on iOS 26.4.

• Fixed: launch crash caused by an over-strict migration plan that iOS 26.4.2 rejected. Removed the explicit plan; SwiftData handles migration automatically.
• Sleep redesigned (from 3.5.6): Lucas suggests naps based on gaps between feeds — tap to log one and adjust the times before saving. No more silent records.
• Reminders that actually fire: the next-feeding nudge refreshes after every save and every sync.
• Faster sync: pending records push within 1 second of saving.
• Crash recovery: a write-ahead log + auto-rebuild from server protects your data through any update or reinstall.
• "Changes waiting to sync" banner so you know if everything is saved.
• Spanish translations across the doctor portal.
