This is an Interval or Circuit Lap Timer app to record lap times and calculate daily averages for groups of athletes, swimmers, cyclists, sprinters etc with an optional defined rest period between laps: the end of the rest period for an athlete is signalled to the coach by an audio-visual alert, even while the app is in the background. The coach can then advise the athlete to start the next lap and tap the appropriate start button when the athlete starts. This app has an interface for starting and stopping the athletes on an Apple Watch if present (iOS12.4+ and WatchOS4.3+). Setting the rest time to 0 enables split-time recording: each press of the Lap End button records the lap time but does not stop the timer. Tapping the Stop All button 'stops' all athletes but does not record a time. Press and hold the Lap End button to stop the lap and the timer. Total time is displayed in this mode. The app handles metric or imperial distances and optional pace calculations. All group members can be started at the same time or individually. Unlimited groups of athletes and athletes within each group are possible. Multiple groups can be on the go at the same time. The current day's lap times and averages for a group or an athlete's past lap times an be shared via email, SMS etc in CSV (comma-separated) format for easy loading into a spreadsheet program. The fifty most recent daily average lap times are shown alongside the current day's average lap time and lap information: lap time and optional pace - minutes per km or minutes per mile. Each athlete in each group can have a different lap length and a different recovery period - double-tap the athlete in the group list to modify the athlete’s lap length and recovery period. Notification of the completion of recovery period occurs even while this app is in the background. There is an optional 5, 10 or 15 second countdown timer when an athlete is due to restart to allow the athletes to be counted down to their restart. The total elapsed time can be refreshed in real time - there is a switch on the Settings screen. This option is not available when in Race Mode on iPad. There is an option to split athletes into two subgroups: those who have started and those who have stopped. The order of the athletes - if not split into two groups - can be rearranged. A 'Race Mode' feature on iPad provides a way to start multiple groups at the same time and/or start athletes individually, and then see them all and stop them as they finish. Started and stopped athletes are split into two groups for easier management. A CSV file with the names of a group's members can be imported into the app. Each line is a member's name, the file name must be the name of an existing empty group and have an extension of '.csv'. Eg: mail yourself the csv file and share it - this app should appear as one of the apps to which the file can be shared. A group can be cloned or deleted. REVIEWS Great For Sports Coaching - 4 stars Version 2.04 - Mar 8, 2016 (UK) [snip] Easy to use, accurate timing and an essential bit of kit if you need to time more than a couple of runners in training or races [snip] Lap timer - 5 stars Version 1.02 - Mar 14, 2013 (UK) Used this lap timer for a running session for a group of triathletes, we set up different rests for different athletes and set them all off. The app worked very well, last split available when they compete that lap. All their splits available at the end of the session. Will use again. App scrolls so you can add plenty of athletes. App does flash up the name of the athlete when their rest time is over.

Verdict
The clearest difference is price: SEN Radio at Free against Circuit Lap Timer's $4.99. SEN Radio also leads on rating (4.7 vs 4.0) and ratings volume (132 vs 2). Circuit Lap Timer's advantage is in-app purchases (none vs 5) and ads (none vs shown). On device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
SEN Radio is free to download; Circuit Lap Timer costs $4.99 up front. SEN Radio sells 5 in-app purchases, starting at $3.49 per month. Circuit Lap Timer asks for nothing beyond the download.
SEN Radio holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: SEN Radio has 132 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 75% of Circuit Lap Timer's written reviews are positive against 52% of SEN Radio's, so the app with the better star average is not the one people write more warmly about.
Circuit Lap Timer ships an update monthly, SEN Radio every 2 weeks. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
