Zonna Run vs Runnerd

You're trying hard. That's the problem. Most runners go medium-hard on everything and never improve. Zonna gives you a zone for each session and holds you to it. Easy when it's easy, hard when it's hard. WHAT IT DOES A training plan built for your race. 5K, 10K, half marathon, or marathon. Tells you what to do each day and why. Heart rate zones paced to you. Calculated from your age and your runs. No guessing, no generic targets. Real analysis after every run. Kit, your in-app coach, reads what you actually did against the zone you should've been in — and tells you honestly. A weekly zone score. Every Sunday: how disciplined was your week. The number you didn't know you needed. A plan that moves. Miss a session, change a day, get injured — your plan reshapes itself, calmly. Apple Health integration. Your runs and recovery sync automatically. Nothing to log manually. WHO IT'S FOR Runners with a day job. People who've got training schedules and conference calls. The ones who keep going too hard because they've only got an hour after work and they want to make it count. If you're a sub-elite athlete running 100+ miles a week, this isn't for you. Zonna is for the rest of us — the runners who blur their zones because life is loud. WHAT'S FREE, WHAT'S PAID Free: a complete training plan for your race, daily session detail, heart rate zone targets, manual logging. Premium (14-day free trial, then £7.99/month or £59.99/year): Kit reads every run, weekly zone score, dynamic plan reshaping that responds to missed sessions or new injuries, post-run pace and heart-rate analysis, continuity across coaching surfaces. PRIVACY Your health data stays on your device by default. Apple Health permissions are read-only. We never write back. No data sold, ever. Full policy at zonna.run/privacy. You can't outrun your easy days.

Runnerd is a running coach and a serious analytics app in one. It builds a plan around your goal, explains every recommendation and works with the runs you've already logged. No subscription. No account. No compromises. HOW IT WORKS Connect Apple Health and Runnerd reads your past runs, whether they came from your Apple Watch, your iPhone or another running app. No blank slate: Runnerd knows where you stand from day one. Keep tracking with whatever you use today. Set a goal, like your next half marathon, and pick a coach. The Patient One builds up carefully, The Ambitious One pushes harder, and The Balanced One sits in between. The difference shows up in your plan, not just in the tone. Runnerd maps out every week until race day and schedules more of the run types you enjoy. You can add your own runs whenever you like. Each morning, your coach checks the plan against your readiness. After each run, it reviews how it went. Ahead of your goal? It'll tell you. Goal asking for more than your coach allows? It'll tell you that too. FOR NERDS WHO RUN Fitness, fatigue and form, running economy, intensity, training load: Runnerd shows whether your training is working and explains every term along the way. It's all built on proven sports science, not AI: Banister for fitness and form, Daniels VDOT for training paces and predictions, Karvonen for heart rate zones.
