Build Recommendations

Prioritized actions based on user demand and market opportunity.

Implement automatic cloud backup with version history

44% of reviews report catastrophic data loss. This is the #1 blocker preventing users from trusting timeline apps. Version history would allow recovery from accidental deletions.

Support unlimited custom date ranges and calendar systems

25% of users need historical/fictional dates beyond 4713 BCE. Writers, historians, and worldbuilders are underserved. Allow custom year formats and unlimited BCE dates.

Build professional export engine (PDF, DOCX, TXT, PNG with high-res)

Users need to print, share, and format timelines outside the app. Current JPG export is blurry and unusable. This is essential for students, writers, and professionals.

Create responsive customer support system

16% cite zero support response. When users lose weeks of data and get no help, they become hostile reviewers. Support is critical for retention and reputation.

Enable unlimited photos per event with media library

Memory tracking requires multiple images per milestone. Current 1-2 photo limit makes the app 'pretty useless for helping me remember events' according to users.
