What this app is. What it isn’t. What you could build.

One-liner

Annotable is a photo annotation and markup tool that lets users draw, write, blur, and label images with various tools, but suffers from outdated design, broken features, and unreliable in-app purchases.

Strengths

Strong core functionality for image annotation (draw, blur, text, highlight) as praised in top reviews
Highly rated (4.65) by 923 users, indicating strong initial user satisfaction
Ranks in top-50 for 'annotate' — proven search visibility and demand
Offers Pro unlock via in-app purchase to remove ads and enable advanced tools
Used by users for creative, educational, and professional workflows (e.g., marking up photos)

Weaknesses

Blur feature is broken on iOS 17+ (reported in 1-star review: 'image blur is broken on ios26')
In-app purchase system is unreliable — users report needing to repurchase frequently, even after valid purchase (‘restarts require switching accounts’)
No updates in over 11 months — multiple users question if developer is still active
Interface is described as 'clumsy' and non-intuitive; basic actions like changing text color don’t work
Pro version purchase option is missing or non-functional (‘no way to actually buy’, ‘can’t update after buying’)

Opportunities

Fix critical bugs (blur, text color, purchase flow) to regain trust and restore functionality
Add modern iOS 17/18 compatibility and SwiftUI-based UI overhaul to improve usability
Introduce cloud sync (iCloud or Dropbox) — missing in current app, a common user ask
Rebuild the IAP system with proper receipt validation and account linking to prevent re-purchase issues
Launch a lightweight free tier with core tools to attract new users while offering Pro upgrade
