ALTIKO
Altimeter for iPhone and Android

You always know how high you are and how fast.

Altiko reads altitude above sea level, speed and heading straight off the device — large, direct, no sign-up.

The same view in light, which is the one meant for full sun. Altiko on iPhone in dark: altitude 2,334 metres, rate of climb +54 m/min, speed 4.2 km/h, the compass above, sunrise and moonrise below.

FEATURES

An instrument, not a menu

Everything is on one screen. Two scales frame the figures — altitude up the left edge, speed down the right: you catch the direction and the magnitude before you read the number.

Altitude above sea level

Where the device has a pressure sensor it carries the measurement - steadier and more precise than GPS alone. Where it does not, the satellite receiver takes over.

Speed over ground

With a noise floor, so the reading rests at zero while you stand still instead of twitching.

A compass that works standing still

From the magnetometer, not from your direction of travel. Corrected to true north.

Rate of climb and the day's highest point

Metres per minute, plus the highest point since you started - highlighted while you are climbing.

Sun and moon

Rise and set for where you are, with the moon drawn at its actual phase rather than as a symbol.

Units chosen separately

Metres with miles per hour is a sensible combination - Altiko allows it. Numbers follow your region's notation, and light or dark is one tap.

IN USE

See it live

Twelve seconds of a climb up the Nordkette above Innsbruck. Altitude, rate of climb, speed and the compass move; the light variant sits behind.

Altiko in use: the altitude rises from 2,334 to 2,382 metres, beside it the rate of climb around +50 metres per minute, below it the speed around 4 km/h, and the compass band turning through south-west at the top.

ACCURACY

Where the altitude comes from

Two things make the altitude more precise.

With a pressure sensor

Most recent phones have a barometer. Altiko uses it for altitude - steadier and more precise than GPS alone. Without one, GPS takes over.

3 m

instead of 10 m vertical

On Android, Altiko reads the GPS receiver directly instead of Google's location service - more precise, and your position never goes to Google.

Altitude is shown above sea level - only on Android 13 can it be off by a few dozen metres. Altiko is not meant for safety-critical use.

PRIVACY
