This app is a remote control for the OnlyT Windows software, used to control a series of timers for a meeting or conference. You MUST have the OnlyT Windows software installed on a computer to use this app. REMOTE APP FEATURES --------------------------------- Timers for each Meeting Part: - independent control of the timers away from the sound desk - start/stop/reset timers - the timer runs on your device and stays in sync with OnlyT every 5 seconds, for a smoother countdown - collapse meeting sections - timer changes from white > yellow (30 secs) > red (overtime) - sound bell for talks that go overtime - optionally hide the start/stop buttons in settings for "read-only" mode - email a summary of timers Fullscreen Timer in Landscape: - optimised for use on the speaker's podium - tap the clock to hide the timer if it is distracting The app can be run on multiple devices at the same time. For example, the meeting chairman can view the timers and could decide to ring the bell for a talk if it is running overtime. Another user could be sitting in his seat in the audience starting/stopping the timers for each talk. And of course the fullscreen timer could be running on a device on the speaker's podium. While the app is running, it will prevent the device from turning off. This can be disabled in settings. The bell can be played from the local device or from the main Windows computer, which is typically connected to the sound system. If it is played from the local device the app will detect the current volume setting, switch it to 100% to play the bell, and then set the volume back to its previous setting. This prevents the device from playing unwanted sounds from other apps and notifications. And of course you are always asked to confirm before the bell is played - just in case you hit the button by mistake. This app is optimised for iPhone and iPad. Split Screen mode is supported on iPad.

Verdict

The call

The clearest difference is monetization model: OnlyT Remote at free against Field Service Assistant's paid. OnlyT Remote also leads on review sentiment (100% vs 85%). Field Service Assistant's advantage is ratings volume (6.4K vs 9) and rating (4.7 vs 4.4). On price, update cadence, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Field Service Assistant holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Field Service Assistant has 6.4K ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 85% of Field Service Assistant's written reviews are positive against 100% of OnlyT Remote's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Field Service Assistant ships an update every 2 months, OnlyT Remote every 6 weeks. The most recent releases landed on October 21, 2026 and October 25, 2026 respectively.
