What's New in Arc Timeline 4

1.5.1

July 16, 2026

• Visits without an assigned place now get their street address filled in automatically as you browse, including city and country, and become findable by city and country in search. (BIG-455) • Set a visit's one-time title to its street address with a single tap. (BIG-227) • Street-address titles display in a lighter style, so they read apart from places you've named yourself. (BIG-634) • Run automatic exports on demand with new Run Now buttons in Settings, and the last-export times shown there are now accurate. (BIG-568) • The AI assistant now handles date ranges like "last 30 days" and "since 2020" correctly, and answers questions spanning long histories more reliably. (BIG-582, BIG-564, BIG-548) • Fixed layout and translation issues in GPX import. (BIG-630, BIG-637)

旧アプリより安定&日本語対応

旧アプリでは、処理中にページ切り替えなどの操作をすると、たまにクラッシュしてしまう事があったのですが、今のところそのような兆候は無く安定しています。

現状の不満点としては、以前は出来ていたライトモード/ダークモードのアプリ内での任意切り替えが出来ない事

Great idea executed awkwardly

Sometimes thinks I walk at 400mph or sleep in a parking lot or am stationary while boating on water. Place search is flaky. Great concept though. Hasn’t changed substancially in years.

Response from developer

Ah the old hater is back. You've been at this 8 years! Never a good thing to say, but still paying for the app year after year. To others reading, I recommend checking the support forum, where we have a vibrant, active, and happy community of users and builders, focused on using and improving the app, taking it to new heights.

無視されちゃう

前のアプリでは、移動してると記録されてるのに、かすりもしない時がある。なんで?

Impressive App, incredible update

Timeline 4 is a massive update and huge change for the better! The UI *flies* now, days and weeks and months load instantly. And finally dark mode! Congrats and thank you to Matt for the job well done, glad for all the work you do.

Still thinks 40 mph is an appropriate walking speed

But it’s a great app overall.
