SkyTimer vs TLAR

SkyTimer is the cockpit companion that tracks your fuel and logs your flight. It draws your aircraft's fuel system as it really is, tells you when to switch tanks, and records takeoffs, landings, and times on its own. On iPhone, iPad, and Apple Watch. *** YOUR FUEL, TRACKED *** SkyTimer estimates fuel used and remaining in every tank, live, from time on each tank and your aircraft's fuel burns. Change fuel flow mid-flight as conditions change, or pick a burn you've set up, like Rich of Peak, Lean of Peak, or Economy Cruise. - Your fuel system, drawn as it really is: from a 172 on Both to a twin with crossfeed, with up to 7 tanks and 4 engines. - Fuel Management Plans set the tanks each flight starts on and when to switch: by time on tank, fuel used, or fuel transferred. Smart Balance keeps your tanks even. - Works with a wide range of fuel selectors, transfer pumps, and crossfeeds. - Start from a catalog of common aircraft, or set up your own. Fuel quantities are estimates. Always confirm fuel with your gauges and a visual check. *** YOUR FLIGHT, LOGGED *** Smart Track uses GPS ground speed and your aircraft's Vso to detect takeoffs and landings, day and night. SkyTimer logs block and flight times, out/off/on/in times, and every airport, including stops, from a built-in worldwide airport database that works without Internet. Automatic detection needs a device with built-in GPS. Every flight goes into your logbook with fuel used, time on tanks, and Hobbs and Tach. Add notes, edit a trip, and export to CSV or LogTen. *** THE NEAREST AIRPORT, WHERE TO LOOK FOR IT *** Nearest gives you the closest airport like a traffic call, "KATW, 9 o'clock, 7 miles," with its runways, frequency, and elevation. *** ON iPHONE, iPAD, AND APPLE WATCH *** On iPad, run SkyTimer full screen or beside your EFB in Split View, Slide Over, or a window. On iPhone, the Live Activity and Dynamic Island keep fuel and times in view while you fly with your EFB. On iPhone Duo, open it up to see fuel, Nearest, and your trip side by side. On Apple Watch, every feature is on your wrist, and the watch keeps tracking on its own if your phone stays behind. Your aircraft and flights sync across your devices with iCloud. *** FREE TO START *** SkyTimer is free to download and logs block and flight times at no charge. SkyTimer Plus unlocks: - Fuel tracking and Fuel Management Plans - Automatic takeoff and landing detection - Unlimited flight storage - Multiple aircraft - Trip editing and export - iCloud sync, and in-flight sync between iPhone, iPad, and Apple Watch One subscription unlocks Plus on all your devices. --------------------- Payment is charged to your Apple Account at confirmation of purchase.

The TLAR ("That Looks About Right!") app is designed to improve general aviation pilot situational awareness of aircraft performance. TLAR computes takeoff, climb, cruise, and landing performance of the following single-engine aircraft types (Expert version allows you to build your own plane type, below are pre-loaded): • Aero L39C (L39) • American Champion Super Decathlon (8KCAB) • Bonanza A36 (A36) • Cessna 150M (C150M) • Cessna 152 (C152) • Cessna 170B (C170B) • Cessna 172M (C172M) • Cessna 172N (C172N) • Cessna 172S (C172S) • Cessna 180K (C180K) • Cessna 182P (C182P) • Cessna T-240 (C240T) • Cessna A185F (CA185F) • Cirrus SR20 (SR20) • Cirrus SR22 (SR22) • Cirrus SR22T (SR22T) • Cub Crafters FX-2 (FX2) • Cub Crafters FX-3 (FX3) • Diamond DA40 (DA40) • Glasair Sportsman (GLSP) • Glasair Glastar (GLST) • Harmon Rocket II (HROC2) • Kitfox 7 Series SS (K7SS) • Kitfox 7 Series STI (K7STI) • Mooney M20F (M20F) • North American Aviation T-6G (T6G) • Piper J3 (J3) • Piper PA18 (PA18) • Piper PA22 (PA22) • Piper PA24-250 (PA24250) • Piper PA24-260 (PA24260) • Piper PA28-140 (PA28140) • Piper PA28-181 (PA28181) • Vans RV-4 (RV4) • Vans RV-6 (RV6) • Vans RV-7 (RV7) • Vans RV-8 (RV8) • Vans RV-10 (RV10) • Vans RV-12iS (RV12iS) • Vans RV-14A (RV14A) The basic version of the app is free.  It predicts aircraft performance using user-entered weather and elevation information in a static fashion like a calculator. The pro version requires a subscription, but offers significantly more features and capabilities. It dynamically recalculates performance in real time responding to the aircraft's 3D position and automatically updated weather conditions. With the addition of airfield information from either the included 73,000 airfield global database or user-defined airstrips, TLAR computes additional performance metrics such as predicted height by end of the runway on takeoff, bearing, distance, glide path, and descent rate required to the airfield, predicted stopping point on the runway during landing, approach stability on short-final, displaying that status visually, and audibly in your headset (for aircraft with communication panels that can connect via bluetooth or cable to your phone). The pro version allows the pilot to set tailorable safety margins and warns the pilot if predicted performance will violate any of the set safety criteria. The expert version adds patent-pending emergency glide functionality, telemetry recording, and automatic landing zone loading. It will tell you where and how high you will be when your aircraft will be capable of conducting an engine windmilling turnback to the runway on takeoff or in cruise. During takeoff and climb it will show you your current wind-corrected glide footprint and announce on headset your latest abort point, when a turnback is possible and show you the route of flight back to the runway along with your predicted altitude when reaching the runway. The expert version also has a heads-up display, NEXRAD radar, custom plane types, and store telemetry. We continue to add features to this version. Supported iPhone models: : X and up Operating system: iOS 17 or better for new interface (14.3 thru 16 will download the legacy TLAR version which has nearly the same functions, but a different interface). Supported iPad models: cellular models required (GPS) with minimum A12 chip performance or greater For more information or to download the TLAR Pilot Manual see www.TLARPILOT.com.
