# RemiPBX vs UltraTone Connect

The clearest difference is rating: UltraTone Connect at 5.0 against RemiPBX's 4.2. UltraTone Connect also leads on update cadence (every 3 weeks vs every 5 months) and iOS requirement (12.0 vs 16.0). RemiPBX's advantage is in-app purchases (none vs 1) and ratings volume (30 vs 5). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. UltraTone Connect sells 1 one-off in-app purchase. RemiPBX asks for nothing beyond the download.

UltraTone Connect holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: RemiPBX has 30 ratings behind it against 5, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

RemiPBX ships an update every 5 months, UltraTone Connect every 3 weeks. The most recent releases landed on October 22, 2026 and September 17, 2026 respectively.
