See arrival times of others without tracking their every move like some apps do. Meeting others gets much more efficient also. Safety, efficiency and privacy seem like a good combination. ### 5/5 — Really good, some quirks *2022-02-12* Love the app. ETA is accurate and let's people know when I arrive, which is handy. Sometimes the beacons don't show the address until I tap on one. The panel on the bottom can get confused when I try to scroll it. ### 4/5 — Missing 1 feature but great otherwise *2022-02-12, version 1.1.0* To the people who made this app. I'm on the road a lot for work and I use beacon to let my wife know I'm safe. My 1 request is to have navigation directions like other map apps. Thank you for making a great app. ### 5/5 — It's been a great family tool! *2022-02-11, version 1.1.0* I was introduced to this app by a friends who has kids. I have a new teenage drive and this helps calm my heart. I wish I could see his precise location while he's driving, but getting ETA updates and notifications when he arrives has given me great peace of mind. ### 5/5 — Great for family reunion *2022-02-10* I first tried this app for a family reunion at a beach house. We all shared our ETA and could see everyone as they approached and even could see when people arrived. It was very cool. I'll be using this for all my long drives. ### 5/5 — Safety and privacy *2021-10-20, version 1.1.0* Lots of potential here. See arrival times of others without tracking their every move like some apps do. Meeting others gets much more efficient also. Safety, efficiency and privacy seem like a good combination. ## Frequently asked questions about Jatter ### What makes Jatter private?
