High-school, college, Olympic and non-elite runners have all trained, ran, and succeeded with the VDOT methodology. -”Dr. Jack Daniels has had a bigger influence on training-for-running than anyone.

Stop digging through your fitness app to find the numbers that actually matter to you. Runalyzer pulls your workouts straight from Apple Health and puts the stats you care about on one screen — always up to date, exactly the way you want them. Build your own dashboard of workout tiles. Each one answers a specific question: How many miles have I run this month? How many 5Ks have I done this year? What's my weekly cycling distance? Tap + and tell Runalyzer what you want to track — it does the rest. Every tile is yours to configure Choose what to display (total distance or workout count), which activities to include (running, walking, hiking, or cycling), your time range, and your preferred units. Add a custom name and pick a color. Stack as many tiles as you want and drag them into the order that makes sense to you. Set a goal, watch it fill Add an optional goal to any tile and a progress ring appears. Hit it and Runalyzer celebrates. Set repeating goals and they reset automatically — your weekly mileage goal is ready again every Monday without you touching a thing. On your home screen Add a Runalyzer widget to your iPhone home screen and your metric is always visible — current value and goal progress, right there without opening the app. Add as many widgets as you like, one for each metric you want at a glance. Dig into any metric Tap a tile to see the full story: your total front and center, average distance, average pace or speed, and a complete list of every workout that went into the number. Sort by date, distance, or pace. Group by day, week, month, or year to see how your training adds up over time. Two charts — distance and pace or speed — show how you're trending. Only count what qualifies Distance filters let you tell Runalyzer exactly which workouts belong in a tile. Count only your 5K efforts, only your long runs, only your rides over 30 km — you set the rules. Pace or speed, your call Running and walking metrics show pace. Cycling metrics show speed. Or override any tile to display whichever you prefer. Your data stays on your phone Runalyzer reads directly from Apple Health and does everything locally. No account. No server. No ads. Apple Health's own permissions control what the app can see. Available in English, Spanish, French, and Brazilian Portuguese.

Runalyzer's advantage is in-app purchases (none vs 17) and chart position (#188 vs unranked). On ads and device support there is nothing between them.
