SmartWOD is the popular CrossFit-style timer, and its workout log and Apple Watch support are real reasons to stay. ClockKeepers is built around the other problem: the whole room seeing the clock. Your phone runs it, and any browser on any TV follows live. Here is a plain comparison, including where SmartWOD wins.
A good fit if you want a workout log with a calendar and CSV export, Apple Watch start, Apple Health, and a timer made for AMRAP, EMOM, For Time and Tabata. Its listing says it can cast to a TV with Chromecast. Its free tier shows ads.
A good fit if you want the clock on the wall without a Chromecast or the app on the TV, no ads, and one price. Open the web app in any TV browser, type a 5-letter code, done. It keeps only a local history log today and has no Apple Watch app.
| ClockKeepers | SmartWOD Timer | |
|---|---|---|
| TV display | Open the web app in any TV browser and type a 5-letter code, or scan the QR from a phone. Nothing installs on the TV. AirPlay or HDMI also work | Casts to a TV via Chromecast, per its App Store text. That needs a Chromecast and the app on the casting phone |
| Phone controls, TV displays | Yes, and every phone, tablet or TV in the room can follow the same clock | Partly: the cast screen follows the phone |
| Workout presets | 14 presets including Tabata, EMOM, AMRAP, For Time, HIIT and boxing, plus a custom interval editor | AMRAP, EMOM, For Time, Tabata and a MIX timer, with one-tap presets |
| Workout log | A local history log on the device. No CSV export or Health sync yet | Workout log with a calendar and CSV export, plus Apple Health. It is ahead here |
| Apple Watch | Not available | Apple Watch start, per its listing. It is ahead here |
| Ads | None | The free version has ads, according to its listing and reviewers |
| Account needed | No | No account needed to use the timer |
| Price model | Free for 1 timer, 3 saved presets and 5 viewers. ClockKeepers Pro is $7.99 once, no subscription | Free with ads plus subscriptions; its listing shows more than one set of prices, and a lifetime option well above $7.99 |
| Multi-timer board | Up to 8 timers on one screen (Pro) | Not listed |
| Platforms | iPhone, iPad, any web browser, Android sideload | iPhone and Android |
Last checked October 20, 2026. SmartWOD details are from its App Store listing and third-party reviews we read in October 2026, not hands-on testing. We could not confirm Chromecast details beyond the listing text. Prices vary by region and change; check each store for the current figures. A feature we mark as not listed may still exist. ClockKeepers details are from our own listing.
ClockKeepers Pro is a single $7.99 purchase. SmartWOD is free with ads and sells subscriptions and a lifetime tier; its App Store listing shows more than one price set, and the lifetime figure we saw is several times $7.99. If you run a box that lives in the SmartWOD log, the subscription may be worth it. If you mainly want a clock the room can see, the free ClockKeepers tier (1 timer, 5 viewers) covers it.
No. The TV only needs a web browser. Open the web app on the TV, type the 5-letter code, and the timer follows your phone.
ClockKeepers has no ads in the free or Pro version. It does not have SmartWOD's workout log with CSV export or an Apple Watch app, so it is not a like-for-like swap for everyone.
You can AirPlay to an Apple TV or connect with a USB-C to HDMI adapter, but you do not have to: the browser route needs no hardware.
Not in the way SmartWOD does. ClockKeepers keeps a local history log on the device. If a calendar log with CSV export matters most, SmartWOD is the better pick today.
One timer and five viewers free, no account, no ads. ClockKeepers Pro is $7.99 once.
