RunSplit is the running app built around the thing that actually makes you faster: clean, color-coded intervals. Green means WORK. Red means REST. No guesswork - just a phone that knows what phase you are in and a coach that runs with you. FREE FOREVER - WITH A TIP JAR RunSplit is completely free. Every feature, every update, no paywall. There's a single ad slot in Settings. Prefer to support a solo developer? Leave a Gel, Energy Bar, or Race Entry tip and RunSplit goes ad-free permanently across every device on your iCloud. SMART INTERVAL COACHING Pick your work and rest blocks in seconds or meters, then tap Start. RunSplit counts you in, tracks the set, and hands you the next interval the second your rest is up. An on-device Smart Coach, powered by Apple Intelligence, talks you through every phase. Choose your tone - Hype, Calm, Drill, or Mindful - and your voice (boy or girl) and you get a runner, not a stopwatch, in your ear. STRETCH BEFORE RUN Three built-in dynamic warmups - Quick (3 min), Standard (5 min), Full (6 min) - made of the 12 stretches running coaches actually recommend: leg swings, walking lunges, hip circles, hamstring scoops, high knees, butt kicks, more. Wire one to a profile and tap Play. Pick "Stretch + Run" or skip. Animated visuals show the motion. Apple Watch chains right into your run when the routine finishes. FREE RUN - JUST RUN No Work/Rest splits, no countdown beeps. Free Run records your GPS route, distance, pace, and heart rate while you set your own pace. Perfect when you want to run by feel. WALK MODE Open record walks with GPS, live steps and heart rate with no Work/Rest bar LIVE CROSS-DEVICE RUN MIRROR Glance at your Apple Watch mid-run and see exactly what your iPhone is tracking. Run from your watch and your iPhone shows the same tile. If a device dies mid-run, the other one still has the live snapshot. FLYOVER VIDEOS Generate a cinematic 3D satellite flyover of any saved run - 9:16, ready to post. Every video opens with an establishing wide shot and closes with a pull-back reveal of the whole route. Duration and camera scale to long routes, elevation gain shows in the HUD, and PACE reflects your actual pace at each point. MOUNTAINS Hike mode auto-tags the highest GPS point on your route as a mountain, builds a Summit Collection, and lets you fix or add a peak retroactively from any past hike's detail screen. ACHIEVEMENTS, PRs, AND TOP-10 MEDALS Marathon distance, sub-5:00/km pace, early-morning run, weekly streaks, per-shoe PRs, mileage milestones. Plus a top-10 medal that lands on every saved run when you place in your lifetime ranks. CONDITIONS - YOUR BODY ON ONE SCREEN Weight, height, body temperature, resting heart rate, HRV, VO2 Max, blood oxygen, walking speed, plus today's steps, exercise minutes, and stand hours - all from Apple Health. Trend charts with a NEW PR badge when you set a lifetime best. SMART CALORIE TRACKING Log meals fast with Quick Add presets, free-form descriptions, or a manual editor. iPhones with Apple Intelligence parse your text into calories and macros on-device. Every other iPhone uses a curated library of 150 runner foods to estimate the same numbers offline. STRAVA SYNC Connect once and every outdoor run pushes automatically. Manual "Push to Strava" on any saved run, with de-dup so you never get duplicate uploads. APPLE WATCH The companion app runs the same interval engine on your wrist. Walk mode counts steps live. Profiles with a stretch routine show "Stretch + Run" instead of Start - same library, same visuals, then chains straight into the run. YOUR GEAR, TRACKED Add a pair, snap a photo, and RunSplit logs every mile. Live wear bar, per-pair pace, cadence, heart zones, total mileage across your rotation. ON-DEVICE, PRIVATE, YOURS No account. No login. No subscription. Your runs, routes, shoes, and music taste stay on your iPhone. The Smart Coach runs on-device using Apple Intelligence. Download free - lace up, pick an interval, and go.

Verdict
The clearest difference is ads: OnTrack Interval Timer at none against RunSplit's shown. OnTrack Interval Timer also leads on iOS requirement (16.2 vs 18.0). RunSplit's advantage is device support (3 vs 1). On price and in-app purchases there is nothing between them.
