Decide before you launch. Paddle Check gives paddle boarders, kayakers and canoeists a fast, clear answer to one critical question: Is it safe to go on the water right now? Built by the team behind PaddlePal, this app turns live conditions into a simple, explainable decision — so you rely on judgement, not guesswork. A CLEAR VERDICT IN SECONDS Open the app, select your craft and experience level, and get an instant result: GO — conditions are favourable. CAUTION — be aware, extra care needed. NO-GO — stay off the water. No charts. No jargon. No scrolling. WHY PADDLE CHECK IS DIFFERENT Most weather and marine apps show raw data. Paddle Check shows what it means for you. It is designed specifically for small craft and considers: • Wind direction, not just speed • Gusts and changing conditions • Tides and currents that affect your return, not just your launch • Cold water risk based on real exposure data • Your craft type and experience level You get the decision and the reason behind it. WHAT YOU WILL SEE • One clear Go, Caution or No-Go verdict • Exactly three plain-language reasons explaining the decision • One practical safety suggestion you can act on immediately That is it. Simple. Focused. Useful. SHARE A FLOAT PLAN Let someone know where you are going and when you expect to return. Paddle Check makes it easy to share a float plan with friends or loved ones before you head out, so someone always knows your plan. BUILT FOR REAL PADDLERS • Designed for SUP, kayak and canoe • Works fast, even on the beach with poor signal • Clean, high-contrast interface built for outdoor use • No accounts, no ads, no tracking Just open it and decide. Paddle Check is created by the team behind PaddlePal — trusted by paddlers worldwide to track sessions and explore safely. This app complements PaddlePal by helping you make the right decision before you even launch. IMPORTANT Paddle Check provides guidance only. It does not replace training, local knowledge, or official forecasts. Conditions change quickly and the final decision is always yours. Think before you launch. Confidence is not a forecast.

Verdict
The clearest difference is review sentiment: Paddle Check at 100% against SPF's 32%. Paddle Check also leads on in-app purchases (none vs 7). SPF's advantage is price (Free vs $3.99) and update cadence (weekly vs every 3 months). On ads and device support there is nothing between them.
