Migri — built by vulnerable, for vulnerable Migri keeps the people you trust connected to you when it matters most. If something happens, one tap sends your lawyer and your trusted contacts your exact location and the signal that you need help — so the people who can act, act fast. We have stood at borders not knowing if we would be let through. We have stopped answering unknown numbers. We have written our lawyer's phone on our arm in case the phone was taken away. Migri exists because we wanted something better for ourselves, our families, and the people who come after us. The first 48 hours often determine whether you come home soon, or much later. A lawyer who knows where you are can call the right people. Family who knows can show up. You are not alone. HOW IT WORKS Set up your attorney and up to 10 trusted contacts once. If you're detained or in trouble, one tap sends them your location and an alert. You can also share your location with your trusted people in the background, so they know where you are even if you can't reach your phone. Your contacts can act immediately — call your lawyer, reach the right people, show up. PRIVACY IS THE PRODUCT Your attorney and trusted contacts are encrypted. Your data is yours. We never sell, share, or monetize anything. FEATURES 1) One-tap alert to your attorney and trusted contacts with your location 2) Optional continuous location sharing with the people you choose — works even when the app is closed 3) Add up to 10 trusted contacts plus your attorney 4) Home screen widget with live status 5) Three intensity modes — Standby to save battery, Maximum for higher-risk moments 6) Offline-safe — your location is saved locally and sent the moment you reconnect 7) Eight languages: English, Spanish, Russian, Armenian, Ukrainian, Kazakh, Tajik, Uzbek (more coming) 8) Light and dark themes Migri is independent and not affiliated with any government or law-enforcement agency.

Verdict
The clearest difference is price: Migri at Free against LeafSpy Pro's $19.99. Migri also leads on update cadence (every 3 days vs every 2 months). LeafSpy Pro's advantage is in-app purchases (none vs 8) and chart position (#10 vs unranked). On ads, device support and iOS requirement there is nothing between them.
