Tracer vs MapPiece

Wait, what time did I get home last night? How many times did I go to the gym last week? When did I visit my client last month? Where did I have lunch the day before yesterday? What time did I leave school? Where were you on that day, at that time? What was your day like? Your iPhone records everything and tells you everything you need to know. Once you've accumulated lots of data, try linking it with other apps. You can export timestamps, addresses, and map data to various apps. You can also export thousands of records to a CSV file with a single tap. The possibilities are endless. Do you use the standard Calendar as your planner? How about this app's unique calendar export feature? Turn your everyday calendar into a visual diary. Many location-tracking apps are useful but come with the constant worry of battery drain. Looks handy, but the battery just melts away... That's no way to keep using an app. Worry no more! This app is not only useful but also minimizes unnecessary battery consumption. Of course, privacy is a top priority. All data processing is completed on your device. No third party can access your location data online. There are 4 types of records: [Pass Point], [Visit], [Region Entry/Exit], and [Track]. [Pass Point] is recorded when significant continuous movement is detected. [Visit] occurs when you remain in the same place for a certain period. [Region Entry/Exit] records when you enter or exit a monitored region. [Track] records detailed movement information while the switch is enabled. Typically, several to dozens of location records are automatically saved each day. You can search through your accumulated records flexibly and powerfully. Specify a date range, define a search area on the map, or enter an address keyword. Retrieve past records exactly as you want, instantly. You can also easily export those search results to a CSV file. [About Premium Features] To help you use this app more conveniently and enjoyably, we offer premium features for a fee. Premium features primarily enable smooth integration of recorded data with external apps. It's a one-time purchase that lasts forever. [When Records Are Unstable] * This app fully utilizes WiFi and cellular networks to obtain location information. It cannot work properly in airplane mode or with WiFi turned off. Please keep WiFi on. * If records are not working properly, please check: Settings > Privacy > Location Services > Tracer (this app's icon) > Always Allow. * Depending on your environment, it may take some time for location recording to stabilize. Please leave the switch on for a few days to see how records are generated. [Important Notes] * This app stores location data locally on your device. Communication with Apple's secure servers occurs only to convert latitude/longitude (which contains no personal information) into addresses and place names. No location data from this app is otherwise shared externally. * Unlike typical GPS trackers, this app does not record meter-by-meter or second-by-second detailed data. Its purpose is to record useful life-level location information as accurately as possible without battery burden. * Continued use of GPS running in the background can dramatically decrease battery life.
