To speed up troubleshooting, include:

  • Your device model, such as iPhone 15 Pro or iPad Pro
  • Your iOS or iPadOS version
  • Your PicDeDupe app version (Settings → About → Version)
  • What you expected to happen and what happened instead
  • Screenshots or a short screen recording if available

App Overview

  • App name: PicDeDupe
  • Core features: duplicate photo and video detection, AI verification, quality ranking
  • Free experience: hash-based duplicate detection with limited free scans
  • Optional paid upgrade: PicDeDupe Pro for unlimited Smart AI Scans
  • Privacy: all scanning runs on-device, no photo data leaves your phone

Most Common Topics

Scan finds fewer duplicates than expected

Open Settings → Detection sensitivity. Strict only matches near-identical images, Balanced is the default, and Loose catches edits, crops, and burst shots. Try Balanced or Loose if you suspect duplicates were missed.

Scan looks slow on a large library

The first scan computes fingerprints for every photo and stores them locally so future scans are much faster. Pro adds Vision verification and quality ranking, which is also cached. Keep the app open and the device awake during the first scan.

Smart AI Scan is locked

Free users get a limited number of full scans before the AI features lock. If you used them already, open the Pro upgrade screen to subscribe or buy lifetime access, or restore purchases if you already paid.

Storage did not free up after deleting

iOS moves deleted photos to the Recently Deleted album for 30 days. To reclaim storage now, open Photos → Albums → Recently Deleted, then Select → Delete All. The in-app banner after a delete provides a one-tap shortcut to Photos.

Restore Purchases did not unlock Pro

Use Restore Purchases inside PicDeDupe and confirm you are signed in to the Apple ID that made the original purchase. If the issue continues, email support with the product you bought and your device details.

Background scan never seems to run

iOS schedules background processing tasks based on device usage and charging state. The app requests a scan every few hours, but iOS decides when to run it. Foreground scans from the Home screen are always available.

Cancelling the iOS delete dialog shows an error

Tapping Don't Allow on the iOS Photos delete prompt is treated as a cancel and not an error. The app suppresses these cancellations silently. If you see a real error message, please share it with support.

Reset fingerprint cache

Settings → About → Reset fingerprint cache deletes all cached image fingerprints. The next scan will take longer because every photo will be hashed again. Use this only if duplicate results look incorrect.

Purchases and Refunds

Payments, subscription renewals, cancellations, and refunds are handled by Apple. For refunds, use Report a Problem.

If Pro access does not unlock correctly after a successful purchase, use Restore Purchases first before contacting support.
