The hardest part of building a habit tracker in 2026: Engagement vs. Friction

Hi community! I’ve been analyzing why most productivity apps fail after the first 7 days. It seems the 'friction' of logging data kills the motivation.

I’m currently building Mentor del 1% and I'm struggling with a specific decision: Is it better to have manual check-ins to build discipline, or automated tracking to reduce friction?

What feature has actually helped YOU stick to a new habit for more than 30 days? I want to build something that truly adds value, not just another notification machine.
