Your grandmother said the family came from Horodek. You type "Horodek" into today's map and find nothing. The village changed countries and spelling four times before it vanished from the registers altogether.
Kresopis links a pre-war place name to its modern counterpart in Belarus or Lithuania where one could be identified. Type the name the way you remember it, even with a typo or without Polish diacritics, and the app finds matches with their interwar administrative affiliation: gmina, county and voivodeship, and, where data exists, the parish (c. 1933). A good starting point for your next search in the archives.
On top of that, a personal family archive built for the realities of the region: one person could have three different spellings of a surname in three different offices, patronymics were the norm, and records were kept by three different faiths. You record people, facts, and family links with any amount of missing data: just a year, just a first name, "somewhere near Nowogródek".
Coverage today: the Nowogródek and Wilno voivodeships. More voivodeships arrive in later versions.
Works fully offline. Your family tree and searches stay on your device, no account, no cloud.
One-time purchase, not a subscription. Place search is free and unlimited. The full family organizer (people, facts, relationships, editing, GEDCOM export) unlocks with a single payment.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
New look and fixes:
• Search and place cards now open with a photo or a WIG map, and the 1937 name and today's name sit side by side.
• On iOS 26 the bottom bar is the system Liquid Glass tab bar.
• Results show the modern district next to the name.
• Settlements that no longer exist now say so, instead of showing an old Polish name as the modern one.
• The empty search screen offers example searches.
• Large text: titles no longer break mid-word, and search scrolls as one page.
• Text-recognition errors were removed from the parish data.
