Thoughtful vs RUNA

Thoughtful is a private space to ponder, write, and reflect. It’s designed to help you capture your thoughts, organize them effortlessly, and revisit them with clarity over time. Every feature is built with care and informed by research on how people process their experiences and memories. The goal is simple: make it easy to record what matters and return to it later. The design follows a clean, native iOS aesthetic paired with simple writing and organization tools, so you can capture thoughts quickly and without friction. Each day lives on its own page, creating a lightweight, structured space that reflects the patterns of daily life. All data is backed up by iCloud, and no one at Thoughtful can read what you write. No account, email, or credit card is required either.
