Major flaw. ### 4/5 — Comment *2023-02-22* Excellent App and very easy to use keep up the good work 🙏Owen Groove ### 5/5 — Duplicate contacts *2022-08-03, version 3.0* Great app! ### 5/5 — Very helpful *2022-06-30, version 3.0* Very helpful tool ### 5/5 — Awesome time saver! *2022-06-26* Why do I have duplicates and triplicates of all my contacts? F*ing Apple. This app fixed it in seconds! ### 5/5 — Super!!! *2022-05-29, version 3.0* Super!!! ### 5/5 — 1 Click *2022-05-23* So easy to use and fast and fast as lightning ### 5/5 — 11,000 duplicates gone *2022-05-03* Our IS department didn’t know we were having this issue on company iPhones and had no clue what to do about it. I read a review for this app downloaded it and boom. Over 11,000 duplicates were gone. Just run it about once a month or whenever I notice a couple ### 2/5 — Troublesome. *2022-05-03* Eliminates duplicates but something kinky in the algo because it conflates many many contacts into one. Especially if all those contacts have a common office number but different mobile numbers. The software producers should ensure that people with diff mobile numbers are not conflated into one contact. ### 5/5 — It’s a Godsend *2022-04-06* I love that it removes duplicates from my Apple 11 in just a few minutes. The only down side is they come back so I have to redo it every two months plus/ minus. The duplicates are not good usable information and I can’t use them. They clog my contacts. Without this app I’d go crazy! ## Most critical reviews (10 lowest-rated) ### 1/5 — Messed up the contacts *2025-11-18* Software takes any related or duplicate contact and mashes the information into one new contact. The title field gets populated with useless text. Mixes up phone numbers. For example, took my phone #s and added them to my wife’s contact info. As a result each time I sent her a text, it basically sent it to me because my number in her contact info became the default. There is no way to restore my original vcf file. It’s not saved in the location I specified. Contacted developer. Email address bounced back as not deliverable. ### 1/5 — Contacts *2025-04-25* The system will crash when trying to load contacts, would like a refund ### 1/5 — App Pago *2025-01-19* Não tem como usar sem pagar **Developer response:** Dear User, We apologize for the inconvenience you experienced. We would need to speak with you to better understand the problem you encountered. Please contact us at support@systweak.com so we can help resolve this issue. Regards Systweak Software ### 1/5 — Doesn’t work. *2024-09-30* Scans and identifies duplicates that’s it. Doesn’t delete them. You can’t delete them. Creates a back up of duplicate duplicates to for what reason idk but doesn’t work as advertised, or even remotely close. ### 1/5 — Much (self) vaunted…Doesn’t work *2024-06-26* Gets to 5% of 38000 duplicates. Stops. Save your money. **Developer response:** Dear User, We apologize for the inconvenience you experienced. We would need to speak with you to better understand the problem you encountered.

Regards Systweak Software ### 1/5 — Duplicate fixer stalls *2022-10-18, version 3.0* Does not complete the job of deleting duplicates - have same amount as when started ### 1/5 — Only temporary fix is the problem *2022-08-02* Duplicates keep coming back so not sure what the app is doing to resolve the fundamental issue so you need to keep reusing the time and time again Nick ### 1/5 — Don’t buy!! *2022-06-07* I have countless duplicate contacts and this app does nothing to remove them. I would like to find a contact phone number so I could cancel before the next renewal. ### 1/5 — Does not work *2022-05-13* This app is not working. It stops at 55% of the contacts that I need deleted, then it goes black and no contacts end up being deleted. Please refund my money! ### 1/5 — Doesn’t work *2022-04-29* Freezes and crashes every single time ## Most praised reviews (10 highest-rated) ### 5/5 — افضل تطبيق/عرن *2025-09-19, version 3.0* افضل تطبيق ### 5/5 — working *2024-05-01* It works **Developer response:** Dear User Glad to know that you love using our app. Regards Systweak Software ### 5/5 — Great *2024-02-10* Top one of the best apps for contacts ### 5/5 — What a work saver!!!! *2023-10-03* This program is certainly amazing! I just found 130 duplicate contacts that I would’ve had to verify and then delete the duplicate off. This would’ve taken me hours and I don’t have hours it took this program less than a second I highly recommend it to anyone who has a bazillion contacts and uses a Contact Mover mover or saver or any other contact related program to merge their contacts. ### 5/5 — Helped me reduce 40,000 contacts down!! *2023-07-14* This app worked to help me reduce the many duplicates I had down from 40,000 to less than 8,000 Thanks so much ### 5/5 — Super!!! *2023-03-22, version 3.0* Super!!! ### 5/5 — Automatic backup and it did its job *2023-02-20* I have suffered from duplicates for well over a decade because syncing with Outlook had created 6-7 copies of every entry. On the recommendation of LifeHacker, I tried this app. Running this app, I went from over 18,000 contacts to about 6,000 in about an hour and I have not found any issues with the contact list in the days since. ### 5/5 — It worked *2022-12-21, version 3.0* 24000 contacts reduced to 3000 ### 5/5 — Perfect! *2022-11-01* Does exactly what it says it will do! ### 5/5 — Very problematic *2022-10-07* It automatically groups hundreds of numbers together making life hell. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
