PB Intervals™ is a high precision (zero time drift), easy to use interval & reaction timer. Whether you're smashing HIIT/HIRT/SIT workouts, perfecting your striking combos, hitting some zone 6/7 efforts, or guiding patients through rehab, PB Intervals™ is a bit like that evil coach; you love them because they're so good...but also kinda hate them because they're so good. DESIGNED FOR PROS, PERFECTED FOR EVERYONE Born from frustration with drifting timers & subscription-based apps, PB Intervals™ brings elite sports experience to athletes of all levels. KEY FEATURES - Zero Time Drift: Whether you’re cycling, boxing, or doing a beep test, say goodbye to inaccurate timing - In-App Session Creator: Easily design your workouts on the go - Interval & Reaction Timers: Sharpen your reflexes with our built-in reaction timer - Randomise Everything: Mix up interval order, rest periods, & durations. Keep your body guessing & your mind engaged - Customisation: Colour-code intervals, set spoken alerts, add motivational messages within intervals. Make your timer as unique as your workout style - Share Your Workouts: Share workouts with friends or clients with an easy export function - CSV Import Function: Import custom workouts via CSV. No more tedious manual entry on a small screen PERFECT FOR: - HIIT Enthusiasts - Cycling Coaches - Martial Artists - Personal Trainers - Physio & OT - Sports Reflex Trainers - Group Fitness Instructors - Athletes in Training - Home Fitness Warriors FAQs Q: Is it a subscription thing? A: Nope. We keep it simple: enjoy the free version with essential features, or make a one-time, small payment for the full version. No recurring charges, just support towards your personal best. Q: What do I get if I buy it? A: The full version unlocks all the goodness. You'll get unlimited saved timers (instead of just 3), the ability to enable hundredths of a second input & display (good for beep tests etc.), plus import & share options (& we'll install many of the timers available on the resources page of the website (yes; this does include the beep test)). It's everything in the free version, but super charged. Q: What’s a Reaction session? A: Reaction sessions spice things up with random interval calls. They're great for sharpening your reflexes in martial arts or boxing, or for creating dynamic workouts for rehab; it can be like those fancy light reaction training tools, but using just your phone & some everyday objects. Again, it's just like having a personal coach calling things out, only with this session, you don't know what they're going to call, or for how long. Q: Is there a free trial? A: There isn't a free trail, but the free version (without ads) lets you test drive the core features. Q: How do I share things? A: On the Home screen or in a folder, hit the edit button in the bottom left. Select the workout(s) you want to share, tap the share button in the top right, & voila! Q: How do I import sessions? A: Easy peasy...Start creating a new workout, scroll to the bottom, & tap ‘Import from CSV’. Just make sure your .csv file is formatted correctly before importing. IMPORTANT NOTE Your safety is the top priority. Before diving into any new workout routine: - Consult with your doctor, especially if you have any health conditions or injuries. - Listen to your body & adjust as needed. - Remember, you’re responsible for your own safety during workouts. - Our routines are offered as-is & may not be suitable for all fitness levels. By using PB Intervals™, you agree to these terms. Train smart, push your limits safely, & most importantly, enjoy it... even if (when) it becomes type 2 fun.
