What's New in Arc Timeline 4

1.7.5

October 7, 2026

• Import your Arc Timeline 3 backups directly from iCloud Drive, in Settings > Backup & Restore. No need to have the old app installed. It brings across only history from before Arc Timeline 4 started recording on your iPhone, so it is for anyone whose earlier years never made it across. (BIG-399) • Place search now finds the branch you are at, not just the best known ones nearby, and lists the closest matches first. (BIG-820) • The timeline now stays on the same day after minimising and restoring the list, and no longer freezes on a new install when doing so on iOS 27. (BIG-740) • Search results now open the day from the weekly, monthly and yearly views, and search answers "per day" and "per week" questions, such as "hours of cycling per week this month". (BIG-826, BIG-563) • Jumping to a timeline item from search now scrolls it fully into view. (BIG-773, BIG-812) • On iOS 26 the Search tab no longer opens the keyboard by itself. Tap the field to type. (BIG-738) • The subscription screen now retries by itself after a connection failure. (BIG-823) • Fixed the visit times legend in Japanese, Chinese and other languages. (BIG-786, BIG-810)

ダメ

前の方が良い。移動しとるのに記録出来てない事が多々ある!もしか、前の削除しなきゃダメなのかな?

Response from developer

「かすりもしない」とのことで、ご不便をおかけしております。訂正されない件も含めて、原因はいくつか考えられるのですが、実際の記録データを拝見できれば絞り込めます。 App Storeのレビュー欄ではやり取りが続けられないので、サポートフォーラム(support.bigpaua.com)にご投稿いただけると直接やり取りできます。日本語のままで大丈夫です。 その際、問題のあった日を表示した状態で、マップ右上の「…」メニューにある「診断データを書き出す」から書き出せるファイルがあると、原因を絞り込みやすくなります。位置情報を含むファイルなので、フォーラムには貼らずに、こちらからお願いしたときにメールでお送りください。お待ちしています。

Ambitious

Drains battery. A lot. Also can’t determine if I travelled by car, airplane, or walked. I find myself doing a lot of correcting.

Response from developer

Hi! There are no known crashes, so what you're experiencing is not normal. Please contact customer support at https://support.bigpaua.com.

Good app, no lag, always active.

So far so good

Thinks I sleep in a parking lot

And walk on water at 500mph ; crashes ; cool idea though.

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. It's at https://support.bigpaua.com/ This hater is not representative (nor do they ever highlight any genuine problems).
