Why this is a gap
Surfaced from a high-intensity complaint with clear willingness to pay and a specific, reachable audience.
The market
Field contractors and estimators lose work when switching apps or looking up info. No search volume, but the pain (app crashes on context switch, lost drafts) is a usability blocker for mobile-first field work.
Competition & the opening
Existing estimator apps (ServiceTitan, Housecall Pro) handle estimates but don't preserve session state on app pause. The gap is simple: background persistence and draft management so users can jump between the app and reference info without data loss.
What's hard to build
Must handle graceful state recovery on low memory, network interruptions, and rapid app switching on Android and iOS. Must also sync drafts to cloud without blocking UI. Edge cases (conflicting edits, stale cloud data) are common in field work. Feasibility 6/10 reflects the mobile-specific challenges around memory management and offline-first sync.
Why now
Mobile apps closing on backgrounding is a solved OS problem, but niche estimator apps skip basic session persistence.
