Android Apps: GPS, Safety, Health and Measurement Tools

Every app here was written, designed and published by me, Zoran Gojković. There is no team behind them and no investor: each one started as a problem I wanted solved on my own phone. They share the same principles - no ads, no subscriptions where a single purchase will do, and no data leaving your device unless you explicitly turn something on.

Four of them measure the physical world: Zero Lap reads your real speed and acceleration from GPS, Magneo turns the magnetometer into an EMF meter and wire finder, and Libella packs nine measuring tools from a bubble level to a RAL colour reader into one app.

Four look after people: Fall Detect recognises a fall and sends an SOS with your location, Wander Guard alerts you the moment someone leaves a safe zone, Panic SOS gives you guided breathing and grounding during a panic attack, and Fewer lowers your daily cigarettes to zero over a plan you can keep.

The rest cover everyday life and play: Tailspot keeps a full health diary for your pet, Destinium brings a hundred astrology and self-discovery readings into one place, and three small games - Color Hunt, Color Plunge and Tap Timing Duel - are there for the minutes in between.

Most are localised into ten or more languages. Tap any card below for the full description, or go straight to Google Play from the app page.
