As a fellow runner, I understand the desire to lace up and hit the road. But I also know the frustration of guessing—guessing what to wear, guessing how the weather will affect your run, and guessing how much fuel you actually need.
That’s why I created RunPrep. Originally designed to solve the "what to wear and what to bring" problem, RunPrep has evolved into a complete smart-assistant for your running performance. We use the same highly accurate weather data you trust on your iPhone to help you plan every aspect of your run.
NEW FEATURES:
• Weather-Adjusted Pace Calculator: Don't fight the heat—adjust to it. Our new algorithm calculates exactly how humidity, dew point, and temperature impact your performance, giving you a realistic "adjusted pace" so you can train smarter and avoid burnout.
• Precision Gel Calculator: Stop guessing your nutrition.…

For developers and the curious
The evidence, sources, measurements and versions behind every label above.
No review analysis published for this app.
“Not assessed” means we could not measure it. It is never a zero and never a pass.
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence, not a finding.
Supporting measurements: not a complete list of possible harms or positives. Measurement vocabulary 1.4 · how these are measured

Each store’s release notes, as the developer wrote them. They are the developer’s words, not ours.

runprepWhat the stores publish. Store ratings are the stores’ numbers, not Appworthy’s, and are never averaged across stores.
From the store listing. Billing terms are read from each purchase’s name — the stores don’t publish them — so treat them as a strong hint, not a disclosure.
These are really on sale; we just can’t tell from the name whether they recur.
Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
Write to [email protected], or use the form. Name the finding, the app version and the evidence that needs correcting. Factual corrections are free and never depend on buying anything.
