Trusted by cautious cleaners everywhere—goldfish with short memories, grandmas who keep every number since 1987, group-chat admins drowning in duplicates, and my dog (he only insists the vet stays on speed dial). If they can’t break it, neither can your messy address book. ContactSweeper keeps your contacts clean, organized, and up to date. You can swipe through contacts, spot duplicates, merge safely, and back up before you make changes. Cleanup stays fast, safe, and satisfying whether you’re fixing a messy address book or keeping it pristine. Smart swipe cleanup lets you archive, favorite, or delete quickly. Duplicate detection helps you find and merge with confidence. Safety is built in with backups and an undo flow so you can revert changes if needed. You can see phone, email, notes, and groups at a glance, track cleanup progress and milestones, and enjoy performance tuned for large contact libraries. Power tools include bulk actions where they matter (merge, dedupe), an undo/restore pipeline to recover recent changes, and visibility into contact groups so you always know where everything lives. Pro upgrades are optional: remove ads, unlock unlimited cleanup and pro features, and get priority access to new power tools as they roll out. Privacy and trust: your contacts stay on your device; backups are for your recovery. Ads use Google AdMob. App Tracking Transparency is respected—if you decline tracking, you’ll get non-personalized ads. Privacy policy: https://russellry.github.io/privacy.html Great for cleaning up years of messy contacts in minutes, merging work and personal duplicates after job changes or phone upgrades, and keeping a lean, accurate address book you can trust. Start a focused cleanup session today—your future self (and your dog’s vet) will thank you. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
