Verdict
The clearest difference is rating: CallHarborUC at 3.8 against RingRx's 2.6. RingRx's advantage is review sentiment (25% vs 0%) and update cadence (every 4 months vs every 9 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
CallHarborUC holds the better App Store score, 3.8 against 2.6. That said, the two scores are not equally well evidenced: RingRx has 58 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 25% of RingRx's written reviews are positive against 0% of CallHarborUC's, so the app with the better star average is not the one people write more warmly about.
RingRx ships an update every 4 months, CallHarborUC every 9 months. The most recent releases landed on October 12, 2026 and October 1, 2026 respectively.
