Backyard Ultra Timer - Frontyard Ultra Timer & Custom Timer
Backyard Ultra Timer – Coded to Endure When the Journey Continues
When the kilometers turn into triple digits and fatigue sets in, your technology must be infallible. Backyard Ultra Timer is developed to meet the demanding needs of ultra-runners and race organizers alike.
This app is not just a timer – it is a strategic partner, honed to perfection in collaboration with one of Finland's leading Backyard Ultra organizations, NUBU (Nummela Backyard Ultra). Whether you are chasing a "Silver Ticket" to the World Team Championship or organizing your own endurance event, this app ensures that the only thing you need to think about is your next step.
Three Timer Modes – From Training to Race Day
The app is built with a modular design, serving three main purposes for both athletes and race directors:
1. Backyard Ultra (Official Race Standard)
This mode is optimized for the classic "6.7 km per hour" format.
- Automatic Lap Counting: 60-minute cycles that reset automatically for as long as the runner can continue.
- Alert Sounds: Automatic audio signals (3 min, 2 min, and 1 min before the start, plus "wake-up" alerts at 5 min and 4 min combined with changing timer colors) tell the runner and crew exactly when to move to the starting corral. At the start moment (0 min), a distinct starting signal is played.
- Clear Visualization: See remaining lap time, total laps completed, total distance (km & miles), and total elapsed time at a single glance.
2. Frontyard Ultra
A modern and dynamic challenger to the traditional Backyard format.
- Tightening Pace: The timer supports a format where the required completion time shortens as the race progresses. The first round is 30 minutes, and the time decreases with each lap, forcing runners to increase their pace as the race gets older. The time limit shortens by 60 seconds on every lap.
- Simulation: The perfect tool for training when you want to simulate increasing pressure and speed endurance.
3. Custom Timer – The Multi-Tool for Training
Because every runner and every workout is different.
- Full Customizability: Define your own "Work Time" and "Rest Time".
- Adaptability: An ideal solution for interval sessions, hill repeats, or rhythm pacing for base endurance runs. You can set a target lap count or let the timer run indefinitely.
Technical Superiority and Usability
- Big Screen & Info-TV Ready: The app scales seamlessly from mobile devices to large screens. Landscape mode is optimized to display time and laps in a large, clear font, making it an ideal information display for a racecenter. Spectators, crew, and competitors can easily follow the real-time situation from a distance.
- Background Mode & WakeLock: The app runs reliably in the background. The processor is kept awake (WakeLock), and the service runs as its own process, so the timer won't stop even if the phone screen goes dark. You can listen to music or podcasts, and the timer will play audio alerts over your audio.
- Responsive Audio Environment: Clear audio signals and start sounds ensure you know the situation without looking at the screen.
Developed in Collaboration with the Best: NUBU
The app's logic and usability have been validated in real-world conditions in cooperation with NUBU (Nummela Backyard Ultra).
Born in the terrains of Nummelanharju in 2022, NUBU has quickly grown into one of Finland's most significant Backyard Ultra events. It started as part of the international Big Dog's Backyard Ultra satellite race and has since established its place as a "Silver Ticket" level competition, where winners have redeemed spots for the Finnish National Team.
The growth of the event has been immense:
- 2023: 49 runners from four countries, with Pekka Aalto winning (33 laps).
- 2024: A year of records, where a large portion of participants exceeded themselves (participants aged 10–63).
- 2025: 74 runners and a fierce 35-lap (235 km) victory by Joni Lepistö.
This app was born from the need to serve this growing community. It brings the professional timing of the Nummela race center to every pocket, whether you are training for your next record or officiating your own event.

IMPORTANT: Ensure reliable background operation To keep the timer running flawlessly during long ultra races, please disable battery optimization and background usage limits for this app in your Android settings. Manufacturer-specific battery savers may otherwise stop the timer when your screen is off. Check your device settings for more details.
