Build a local-first journal centered on one-tap mood logging, short notes, photos, categories, and simple pattern summaries. Provide automatic encrypted backup, straightforward export and restore, and an explicit feature-and-price screen before onboarding. Launch with a free core journal and either a clearly priced one-time upgrade or an optional backup subscription without promotional pop-ups.

Subscription fatigue and manipulative onboarding are creating an opening for a trustworthy alternative. Reliable device migration is increasingly important as users accumulate years of personal records across phone replacements.
