Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Central Office holds the better App Store score, 4.4 against 3.2. Both are backed by a comparable volume of ratings — 19 and 9 respectively. Written reviews complicate that: 75% of Central Office's written reviews are positive against 86% of TeleGo's, so the app with the better star average is not the one people write more warmly about.
Central Office ships an update every 8 months, TeleGo every 5 months. The most recent releases landed on September 17, 2026 and September 13, 2026 respectively.
