SailfishOS: Pitot

First post of undoubtedly many to come in my SailfishOS adventures. This time it’s to tell about a small app I made during the weekend.

Pitot is a simple GPS/GLONASS speedometer for Sailfish. It will display the current speed of the device in big letters on the screen. It has a few different units, including kilometers per hour, meters per second, miles per hour and even knots.

It still needs some polish and a good smart cover. Also, it can’t be released in the Jolla Harbour yet, since it uses QtPositioning to get the speed.

Having used it a couple of times, it seems that the Jolla phone’s GPS is really terrible, though, since it takes ages to get a speed reading and when you do, the readings jump up and down even though your speed is constant. It also seems the resolution of the speed readings is too bad for trying to measure walking speed – I either get 4.5 or 5.4 kph, nothing in between.

Hopefully I get enough time to finish it next weekend. Now I’ll have to be off to work!
