How to use Belly
Set up boxing rounds or rest between workout sets.
Sets or rounds
Workout sets wait while you work. Tap Play for rest after each set.
Boxing rounds start with ten seconds to get ready. Choose the number of rounds below Play. Rest follows each round except the last.
Set your time
Turn the outer grip to set rest. In Rounds, turn the inner edge of Play to set round time.
Clockwise adds time. The dial snaps near whole minutes. One turn is twelve minutes.
The red triangle moves back to the dot during countdown.
Play, pause and skip
Tap Play to start or pause. In Rounds, tap the center. In Sets, tap anywhere.
Skip moves ahead. Rewind goes back, or returns to the last set or round during rest.
Drag to change time, even while running or paused. Time already elapsed is kept.
Voice control
Turn on Voice and allow the microphone. Start each command with Belly or Bell.
“Stop” pauses. “Finish” ends the session. In Sets, “rest” starts your break.
Check the help below if Voice won’t start or stops listening.
- “Belly, go”
- “Belly, pause”
- “Belly, rest”
- “Belly, set rest to two minutes”
- “Belly, set round time to three minutes”
- “Belly, stop listening”
Sound

Voice, sound & device help
If voice will not start
Check this website’s microphone permission. On iPhone, also allow your browser in Settings → Privacy & Security → Speech Recognition, and check Settings → General → Keyboard → Enable Dictation. Return to Belly and tap Try again.
Speech-service errors differ from microphone denial. Check your connection, open Belly directly in Safari, and check Screen Time or managed-device restrictions. Open Browser details in the voice message to see the reported reason. If needed, reload and tap Voice again.
If listening pauses
Heard shows a possible command. Green confirms a command was received.
Leaving the page or a microphone interruption pauses listening. Tap Resume mic to resume. Returning never turns the microphone on automatically.
If the bell is silent
On iPhone, turn Silent Mode off. Tap Enable sound in the sound notice. Check device volume, Silent Mode and browser sound settings. Another app, Bluetooth routing or a call can interrupt sound or the microphone.
Belly requests mixing with music where supported. On iPhone, listening can still pause music or podcasts. Leave Voice off when uninterrupted music matters. Headphones help recognition during music.
Voice may need the internet. Your browser may process speech through its service. Browsers cannot guarantee bells with a locked screen or in the background. Test sound on your actual device before training.
Privacy and analytics
Effective date: October 17, 2026. Julio Gonzalez is the individual operating Belly Rounds. No account is required.
Website
Your timer settings stay in this browser. Clear the browser’s site data to remove them.
Vercel Web Analytics measures page views, referring sites, and broad device and location patterns to help improve Belly. Vercel says it uses no cookies, stores aggregate data, and does not keep an identifiable browsing history. Vercel’s analytics privacy information.
Belly sends no timer settings to web analytics and uses no advertising pixels. Do Not Track, Global Privacy Control, or the choice below prevents the analytics script from loading.
Website Voice is off until enabled with microphone permission. Your browser may send audio to its speech service and may need the internet. Belly does not save recordings. Leaving the page or a microphone interruption pauses listening. Returning does not automatically restart it.
iPhone and iPad app
Timer settings and session state stay on your device. Belly does not upload chosen times, round counts or workout history. Deleting the app removes local preferences, subject to Apple’s backup and restore settings.
App Voice is optional and off until enabled with microphone permission. Apple’s on-device speech frameworks process audio and command text using a supported local English model, which Apple may need to download. Belly saves no audio or transcripts and sends neither to analytics. Turning Voice off releases the microphone. Interruptions may require you to resume listening.
Live Activities show timer information and controls through iOS on your device. Optional local notification cues need permission and depend on system delivery. Belly uses no remote push timer service. Listening while locked depends on iOS and device conditions. Uninterrupted recognition or bells are not guaranteed. Manage microphone and notification permissions in iOS Settings. Apple’s privacy policies govern system services, model downloads and diagnostics.
Optional app usage sharing
App usage sharing starts only when you choose Share usage in the app’s Privacy and analytics area. There is no preselected choice. Every timer feature works with Don’t share or no choice. The website choice above does not change the app’s setting.
If you opt in, feature signals count session starts, dial adjustments, accepted timer controls, enabling Voice and opening the guide. They can include Sets or Rounds, which dial and input method you used, and whether a control was used in the app or on the Lock Screen.
Signals contain no name, email, user, device or installation identifier, audio, transcript, chosen duration, round count or workout history. They become daily totals, without individual event histories or profiles. Belly uses them to improve features, not for advertising or tracking across apps and websites.
There is no saved analytics queue, retry or later catch-up. Some actions may not be counted. Choose Don’t share in the app’s same area to stop future sharing and cancel work in progress. Already received requests cannot be taken back, and an individual contribution cannot be identified or removed from combined counts.
Hosting, storage and retention
Vercel serves the website and receives optional app usage signals. For service operation and security, it processes IP addresses, approximate city and country derived from IP, and connection and security information. This is separate from Belly’s feature payloads and counter store. Belly requests no GPS or precise location for analytics.
Upstash stores combined app feature counts. Belly does not forward your IP address or incoming connection headers to it. Counts expire from the live store within 90 days. Some may expire sooner. A full 90-day history is not guaranteed. Providers may retain protected backups, inactivity archives or security records under their policies. No fixed deletion deadline for every provider copy is promised. Read the Vercel privacy notice and Upstash privacy policy.
Support information
Email is optional and separate from analytics. We receive your email address, any name you provide, message and chosen attachments to respond and help. Our support mailbox uses Zoho Mail with a forwarding rule to Gmail. Our policy is to delete resolved conversations from both Zoho Mail and Gmail within 90 days of resolution, except legally required retention. Provider backup or security records may remain under their policies. This does not promise deletion of every provider copy. Deleting the app does not remove support messages or combined counts held separately.
For privacy questions or requests about information you sent, contact support@bellyrounds.com.
Support
Email support@bellyrounds.com for help with Belly.
Tell us whether you use the website or app, what happened, and what you expected. Include your device model, browser or app version, and iOS version if relevant. A screenshot can help. Remove private information first. Please avoid sending sensitive information or voice recordings.
For a silent bell, check Belly’s Sound control, volume, sound settings and audio output. Calls, other media and Bluetooth routing can interrupt playback. Test sound and Voice on your actual device before training. The device help above covers browser permissions and interruptions. App Voice needs a supported local English model and microphone permission.
