Move a penlight or any glowing object in a dark room, and the app records its path as luminous trails in photos and video. Nothing is computer-generated — every streak is real light.
使い方
Getting started
部屋を暗くします。暗いほどきれいに撮れます。
シャッターを押して、光る物を動かします。
写真モードは指定した秒数で自動的に撮影、動画モードはもう一度押すと停止します。
ガイドテンプレートを使うと、ハート・星・円などの形に沿って光跡を描けます。
Darken the room. The darker it is, the better the result.
Press the shutter and move your light.
Photo mode captures for the duration you set; in video mode, press again to stop.
Guide templates let you trace shapes like hearts, stars, and circles.
きれいに撮るコツ
Tips for better shots
LEDペンライトがおすすめです。
三脚や固定台を使ってください。カメラが動くと光跡がずれて写ります。
光が写らないときは感度を上げてください。周りの明かりまで写るときは下げます。
残像はOFFで軌跡が消えずに残り、上げると彗星のように流れます。
An LED penlight works best.
Use a tripod or a stable stand — if the camera moves, the trails come out misaligned.
If the light isn't picked up, raise Sens. If ambient light shows up too, lower it.
With Trail off, streaks stay forever; raise it and they fade like a comet.

Start recording and ride a train, and the app identifies and records the stations and sections you rode. The sections you have ridden are colored on the railway map.
Before you board, tap "記録を始める" (Start recording) on the Home tab, or ask Siri.
Stop recording after your ride. If you forget, the app notifies you after one hour without riding a train, and stops automatically after three hours without riding (with a notification). It never stops while you are riding, even on a long Shinkansen trip.
No setup is needed. Settings (調整) are grouped by what you want to do, each with a short explanation.
To see the map without a signal on the train, save the map in advance ("この辺りの地図を保存" on the map, or Settings → 地図の保存).
JR and private railways (including monorails, automated guideway transit and trams) are supported. Subway lines (Tokyo Metro, Toei Subway, and municipal subways in other cities) are not supported. Lines that run underground for long stretches (such as the Minatomirai Line and the Rinkai Line) may not be recorded well, because GPS does not reach underground. In particular, if both the boarding and alighting stations are underground, the app may not notice the ride.
Underground (stations, shopping arcades, passages) and inside large buildings, the app cannot tell your position well, so rides may not be recorded, a ride may appear that you did not take, or the battery may be used more than usual. You can hide a ride you did not take by swiping it left in Records (記録) and tapping "隠す" (you can restore it later).
If you tap "記録を始める" (Start recording) before each ride, "While Using" location permission is enough. A blue location indicator is shown while recording.
Recording uses battery because it uses location. When you are not on a train, the app reduces location use. A portable battery is handy on long travel days.
The experimental "記録をずっとオンにしておく" (Keep recording on) in the Lab section of Settings (調整) records rides without opening the app. Because it checks your location all day, it uses more battery than recording only while riding, and even more inside office or school buildings and underground. It requires "Always" location permission.
On iPad, you can view your map and records. To record rides, please use an iPhone with GPS. iPads with Wi-Fi only have no GPS, so rides usually cannot be recorded.
To see your iPhone records on iPad, make a copy on your iPhone and restore it on your iPad.
Your records stay on this iPhone. They never reach the developer.
Backups (copies of your records)
About once a day, the app makes a backup of your records and keeps it on your iPhone. Each backup contains all your records from the first day, so deleting old backups never deletes records.
If you turn on "iCloud Drive にも置く" in Settings (調整) → 記録をなくしたくない, copies are also saved to your own iCloud Drive (off by default). You can restore from there if you lose or change your iPhone.
To save to Google Drive, OneDrive, etc.
Records (記録) → 記録のコピー → Make a copy (自分でコピーを作る)
Tap "コピーをしまう場所を選ぶ" and choose where to keep it
A folder named "NottaLine" keeps things tidy. To be able to go back months, save a copy this way from time to time.
To restore
Records (記録) → 記録のコピー → Restore from a copy (コピーから記録をもどす), then choose an iCloud Drive backup or a saved file. Deleting the app also deletes the records and backups on your iPhone, so restore from iCloud Drive or a saved file.
Please note
Backup files contain where and when you rode. Please do not post the files, or pictures of their contents, on social media.
Japanese text may look garbled in OneDrive and other apps, but the file is fine and can be imported into this app as is.
It is normal that some rides are not recorded. Most can be fixed later in Records (記録). The same help is in the app: Settings (調整) → 困ったとき → 線路が記録されなかったとき (readable offline).
Forgot to tap "記録を始める" (Start recording): If you started during the ride, open that ride in Records (記録) and tap "+" (Add sections) at the top right to add the sections before you started. A ride that was never recorded cannot be added for now.
The first or last station is missing: Right after departure, or after a long wait on the platform, one station may be missed. Open the ride in Records (記録) and tap "+" to add it.
"記録できなかった乗車" (a ride that could not be recorded): The app could not decide the stations. Open it and tap "+" to choose the stations you rode. If you did not ride, swipe it left in the list to hide it.
A parallel line was recorded: Open the ride in Records (記録) and tap the wrong section to change the line or the train you rode.
Location is not allowed: In iPhone Settings → のってるライン → Location, choose "While Using the App" and turn on "Precise Location". While recording, a notice appears on the Home and Map screens if permission is missing.
You closed the app (swiped it up in the App Switcher): Swipe up from the bottom edge and pause to open the App Switcher. Swiping NottaLine up there closes the app and stops recording (you will get a notification). Open the app to resume. Just going back to the Home Screen keeps recording. Sections missed while the app was closed can be added to the previous ride.
The line you are on is not among the choices in "何線ですか？": The app asks with official line names, which can differ from everyday names (for example, the Keihin-Tohoku Line is officially the Tohoku Line and the Tokaido Line). Subways, freight tracks, or a misread station can also leave the right line out. You do not need to answer; the app decides by itself. You can change the line later in Records (記録).
Underground, tunnels, large buildings: GPS may not reach, so rides may not be recorded. Tunnels are filled in along the track. Subways are not supported.
Low battery / Low Power Mode: Below 20% battery or in Low Power Mode, the app checks location less often and may miss short sections. Below 20% and not on a train, recording stops and you get a notification. Tap "記録を始める" again when you ride.
Sections without GPS (underground, tunnels) are filled in along the track between stations and marked as not confirmed by GPS.
Please let us know via Settings (調整) → 困ったとき → Send feedback in the app, with the date and the sections you rode.
If your mail app does not open (for example, if you only use the Gmail app), copy the address, subject and app details on the Send feedback screen and paste them into the mail app you use.
When you send an email, your email address and the name set in your mail app (which may be your real name) reach the developer. If you do not want your name to be known, check the name setting in your mail app before sending. We use your email only to reply and to investigate problems, and never give it to anyone else.
There is a Full Version (one-time purchase) and a free 3-day trial. The trial never turns into a purchase. If a purchase is not reflected, make sure you are signed in with the same Apple Account used for the purchase, then tap "Restore Purchases" on the Full Version screen.
Whirlwind Championship results are sent only while you are signed in to Game Center. Every game can be played without signing in. Rankings are split into iPhone and iPad divisions, each over the last 30 days and all time.
