SKI SMARTER, STAY TOGETHER You arrive at a new resort, it’s dumping snow, visibility is… questionable, and everyone in your group swears they “know the way.” OpenSlope is the friend who actually does. Open it up and you get ski maps that feel alive—satellite detail with topo lines so you can read the mountain, see what’s steep, what’s mellow, and where that “easy” run suddenly turns into a leg-burner. You can check elevation profiles and slope insights when you’re deciding whether to send it… or save your knees for après. And the best part: once the map is loaded, it’s yours. No signal? No problem. Chairlift Wi-Fi not working? Shocking. OpenSlope keeps going offline. Now for the real reason you’ll love it: your crew. Share a simple code, and your friends pop onto the map as colorful markers—so you know who’s already at the lift, who took a “shortcut,” and who’s somehow stopped in the middle of nowhere. It keeps updating even when your phone is locked, and for privacy, locations fade out automatically after 15 minutes. No awkward “why are you still watching my dot?” moments. OpenSlope is built for ski days: accurate tracking, smooth navigation, battery-friendly in the background, and it works at resorts worldwide. No account, no drama—just open the app and ride. Perfect for day trips, exploring bigger mountains, and keeping tabs on your ski buddies when the plan inevitably changes.
Pistol Analytics
Read full descriptionHide full description
A training log and analysis tool for 10 m air pistol, built for athletes who read data critically. Record shot by shot during training. The entry pad is designed for the range: four keys, a per-series counter, and no running total — because score awareness during a session pulls attention from process to outcome. WHAT IT ANALYSES · Series consistency and standard deviation · Phase-by-phase performance across a 60-shot match · Trends per session format, never pooled across incomparable ones · ISSF final simulation with official timing and decimal scoring · Shot-by-shot scorecards on every session STATISTICAL HONESTY Every figure states its sample size. Claims about order within a session are tested against a shuffled null, so patterns that appear in pure noise are not reported as findings. Where the evidence is too thin, the app says so instead of inventing a number. FOR COACHES An athlete can grant a coach named, revocable permissions. A coach sees only what they have been given, and only while the athlete allows it. YOUR DATA Sleep, stress, mental fatigue and concentration are optional and treated as health data, recorded only if you separately consent, and erasable without touching anything else. Export everything you have entered at any time. No advertising, no analytics, no trackers. Available in English, French and Italian.

Verdict
The clearest difference is device support: Pistol Analytics at 3 against OpenSlope's 1. Pistol Analytics also leads on iOS requirement (15.0 vs 17.6). On price, ads and in-app purchases there is nothing between them.
