Record your X following and followers and check who appeared, disappeared or returned. Changes reflect the time of fetching; the app does not determine causes such as unfollowing, suspension or account deletion. After additional consent and X authorization, you can follow or unfollow from the list. Follow actions use the official X API. Results are saved on your device; if a result is unknown, check X before trying again. Connection changes Compared with the last snapshot before the period. If there is none, the first snapshot is the baseline. People in the same state as the baseline, such as those who disappeared and returned, are not shown. Changes between fetches cannot be observed. On iPhone and the web, accept the terms and sign in with Apple before using the app. Allowances are managed per Apple sign-in. No separate ID or password registration is required. You can link up to 5 X accounts. Connections They follow you, you follow them, or both. Find connections by name. Save following and follower counts with the time they were fetched. Add records from ZIP Read your X archive on your device. Free, with no X linking required. Records and storage Records are stored on your device, up to about 1 GB across all accounts. There is no fixed limit on following, followers or saved snapshots. The first snapshot is the baseline. We do not determine why someone disappeared. Monthly plans Fetches are shared across up to 5 accounts. Successfully fetching one accountβs following and followers uses one fetch. Fetch manually at least 12 hours after a success. Unused fetches do not roll over. There are 5 free tickets in total, with no automatic conversion to a paid plan. An upgrade applies as soon as Apple confirms it; a downgrade applies at the next renewal. Only one monthly plan can be active at a time. After cancellation, you can use the plan until the subscription period ends. Cancel through the App Store. Saved records remain viewable after your subscription ends. Check suspension Pressing Check suspension sends the personβs X ID through the relay to twitterapi.io to check their current status. Each person checked uses one check, including unknown results and communication failures. This is separate from list fetching: linked accounts share 10 checks per month, resetting at 00:00 Japan time on the first day of each month. Relay results expire after 1 hour and are removed every 5 minutes. Identifiers for usage limits, usage times and hashes of target IDs are retained. Results reflect the time of checking and do not prove why someone disappeared. This app uses the third-party service twitterapi.io instead of the official X API to keep data retrieval costs down. twitterapi.io is operated by Prism Digital, LLC, based in the United States, and is independent of X.
