PrefixPlus allows you to add the prefix number to phone numbers in Contacts at once. Phone numbers with the prefix number will not be replaced but added to contacts. For example, if you set the number "+81" and the label "Call(JP)", contacts will be updated as follows. [Before update] Home: 03-1234-5678 Mobile: 090-1234-5678 [After update] Home: 03-1234-5678 Mobile: 090-1234-5678 Call(JP) Home: +81-3-1234-5678 Call(JP) Mobile: +81-90-1234-5678 (Caution) Be sure to back up contacts as security against accidents. For example, if you back up to iCloud, you can restore contacts at some point in the past. Please note that you can add prefix numbers to contacts synchronized with local, iCloud, Gmail only.

Verdict
The clearest difference is ads: ZUConverter at none against PrefixPlus's shown. ZUConverter also leads on review sentiment (100% vs 72%) and rating (5.0 vs 4.7). PrefixPlus's advantage is update cadence (every 2 months vs every 49 months) and ratings volume (1.1K vs 3). On price, in-app purchases and device support there is nothing between them.
