Drip Strips vs Pilot Toolkit by Hangar Flying

The official scanner app for Drip Strips water testing strips. Scan, save, and chart your water readings just as easily as taking a photo. View graphs of your tests, export the readings, and share the results from any desired time frame. The Drip Strips scanner is tailor made to support our line of water testing kits, and is not compatible with other brands.

Pilot Toolkit is a free set of more than 75 flight planning tools. Every calculator works with no signal. No ads, no account, and nothing to upgrade. SAR/ISR TOOLS • SAR/ISR Mission Planning: on-station time and fuel, reserve, minimum RTB fuel, and Zulu times for arrival, break station and landing. The answer stays on screen while you edit, and it warns you in plain words if the fuel or time doesn't work. Share the brief as text or PDF. • Search Pattern Planner: expanding square, sector, parallel track and creeping line, with wind-corrected legs, total time and fuel, and a drawing of the pattern. • Search Area & Coverage: the area you can cover, the time you need, and the coverage factor. • Mission Timers: countdowns to arrival, bingo, break station and landing, with phone alerts. Mission Planning can set them for you. • SPI Orbit Data: turn radius, turn rate, time for 360° and offset from a sensor point of interest. Enter your bank angle, or let it assume one and label it. • Sensor Geometry: slant range, ground range, depression angle and the size of the picture on the ground. • Grid Coordinates: convert between lat/long, MGRS and UTM. • Cruise Performance: enter your own altitudes, fuel flows and true airspeeds for any aircraft, and compare fuel and time for your trip. FLIGHT COMPUTER • Airspeed: true airspeed, CAS, EAS, Mach, crossover altitude, planned Mach and TAS, Vref • Wind & Heading: wind correction, crosswind, find wind, fixed groundspeed • Time & Fuel: time, speed and distance, endurance, fuel flow, ETA, time adder, journey log, crew rest • Altitude: density, pressure and true altitude, cold temperature correction, device altitude • Climb & Descent: rates, gradients, stabilized descent, visual descent point, vertical path deviation, time to MDA • Navigation: route map, GPS flight mode, closest airports, critical point, equal time point, point of no return, turns, DME arc • Weather: METAR, TAF and D-ATIS, sunrise and sunset, sunset on your route, humidity, cloud base, ISA deviation • Weight & Load: passenger weight, cargo and floor load, runway slope, C.G. change, interpolation • Conversions: units, fuel weight by temperature, QFE and QNH, coordinates, gradients Star the tools you use most to keep them at the top. Light and dark themes are included. Everything you enter stays on your device, and your location is never sent anywhere. Maps and live weather need a signal: when you ask for weather, the airport code goes to the weather service, and nothing else does. Built by a working pilot and Hangar Flying. Planning aid only: check every figure against your aircraft's approved flight manual and current data.
