Speed Gonzo: GPS Speedometer app analytics for September 28

Speed Gonzo is a GPS speedometer for people who think mph is fine, but nine other units are better. It does the responsible thing first: accurate real-time GPS speed, a big circular gauge, and a chunky digital readout you can see at a glance on the dash, the bike, or the boat. The screen stays awake while you drive, so your speed never goes dark. Very normal speedometer behavior. Then you swipe left, and things get a little unhinged. TEN WAYS TO KNOW HOW FAST YOU'RE GOING • Miles per hour (mph) and kilometers per hour (km/h), for the responsible adult in you • Knots, for pretending you're on a yacht even though you're in a Honda Civic • Meters per second, for showing off at parties nobody invited you to • Leagues per hour, because Jules Verne would want you to • Percent of light speed, so you can find out exactly how far you are from warp drive (spoiler: very far) • Furlongs per hour, a deep cut for horse racing fans and nobody else • KiloAttoParsecs per hour, an old physics-nerd joke unit that finally got the speedometer it deserved • Smoots per hour, a tribute to one very patient MIT pledge and one very long bridge • The GREG, a completely unscientific unit with a suspiciously scientific backstory involving a 1985 DeLorean Swipe to switch units instantly. Tap any unit name and a little dialog explains, with a straight face, why it exists. Some are real history. Some are real physics. One of them is just a guy's wingspan times 88. MAKE IT YOURS • Calibrate to miles or kilometers • Four dial color themes: green, Tron blue, cherry red, and orange • A fixed reference marker keeps 60 mph (or 100 km/h) on the dial at all times, no matter which ridiculous unit you've wandered into So yes, it's still a real, useful speedometer for driving, cycling, boating, running, or checking how fast the train is going. It just also happens to know your speed in Smoots. GOOD TO KNOW • Uses your phone's GPS; no car connection or extra hardware needed • Speed accuracy depends on GPS signal, so open sky works best • Always obey posted speed limits and don't fiddle with your phone while driving. Mount it, pick your unit before you roll, and let a passenger do the swiping. Speed Gonzo is for anyone who's ever looked at a normal speedometer and thought: this is fine, but what if it also had opinions.
