【Workout Diary】 is a ride, run, and hike companion that captures every route with clean visuals and immediate performance insights. It blends live tracking, historical records, and clarity around permissions so you always know how the app supports your training. **Live ride console** Launch workouts from a full-screen map with GPS lock indicators, instant speed/distance readouts, and a slide-to-end action that prevents accidental stops. Switch between cycling, running, and hiking in one tap to keep stats consistent. **Deep record insights** Browse past sessions through scrollable cards, tap for per-route distance, pace, ascent, and time, and compare any month at a glance. A radar-style ability chart turns raw numbers into an easy score for each sport. **Calendar heatmaps** Weekly, monthly, and yearly views pair heatmaps with tabs for distance, time, ascent, and frequency so streaks and gaps stand out immediately. Charts respond the moment you scrub the calendar, keeping every plan grounded in real data. **Permission guidance** A dedicated permission center shows the status of location and health access plus a numbered checklist that walks you through iOS settings whenever something is missing. You always know which access is needed before the next ride. Plan multi-sport training with confidence and let 【Workout Diary】 turn every outing into actionable insight.

Verdict
The clearest difference is in-app purchases: Workout Diary at none against Stego's 2. Workout Diary also leads on ads (none vs shown). Stego's advantage is update cadence (every 2 months vs every 5 months). On price, device support and iOS requirement there is nothing between them.
