How they differ
Immio records the country you are in by GPS. Pebbles asks for no location permission and has you enter trips yourself.
Or pick Residency
Residency takes a third route: it reads the trips out of the photos you choose, so the history is there without GPS and without typing.
Residency is an iPhone app that builds your travel history from your photo library and counts your days against visa, tax residency and citizenship rules. It warns you before you cross a limit and shows what a planned trip would change.

What Immio is
Immio counts your days abroad automatically and keeps you within tax residency, Schengen and visa limits. It logs the country you are in by GPS in the background, imports a spreadsheet of past travel, and draws a map of the countries you have visited.
What Pebbles is
Pebbles tracks your days in countries and US states for tax residency, visa limits and citizenship planning. Logging is manual by design: its listing says it needs no GPS or background location permission.
