iOS apps for people who spend time outdoors

TraxLabs LLC is an independent studio that builds iPhone apps around live data from USGS, NOAA and Apple WeatherKit.

Agencies and forecasters publish a lot of useful information about rivers and the sky, but it is rarely easy to read from a riverbank or a trailhead. Our apps turn it into a plain answer to the question you actually have: is it worth going out today?

RiverTrax

River levels, flow, forecasts and alerts

RiverTrax shows live readings from thousands of USGS and NOAA gauges: gauge height, flow in CFS, flood stage, trend and forecast. For creeks with no gauge nearby, it gives an estimated flow and a 10-day outlook modeled by NOAA, labeled as an estimate. Set an alert for flood stage or for the range you like to fish or paddle, and keep notes in the River Journal.

LightTrax

Sun and sky planner for photographers

LightTrax shows golden hour and blue hour at your exact spot, with an outlook that says whether tonight's sunset or night sky is worth going out for, and why. It reads the terrain around you to find when the sun really drops behind the hills rather than the textbook time, and it logs how the light turned out at the spots you save. Forecasts come from Apple Weather.

Steelhead Alley river conditions

Live flow for the Lake Erie steelhead rivers of Ohio and Pennsylvania, each compared to what's normal for the date. Every gauged river has a 14-day flow chart and, where one has been published, the range anglers say fishes best. The river pages also cover access, parking and run timing, and creeks with no USGS gauge point you to the nearest stream that has one.
