Ember helps you cut down or quit through gradual reduction: you log the cigarettes you smoke, and the app shows your progress, helps you ride out cravings, keeps a reduction plan, and holds a wellbeing diary. The app runs fully on your devices, with no network and no accounts. The interface follows your device language: the app is localized into 10 languages, English among them.
Write to intromen@icloud.com - describe the problem or suggestion and, if relevant, include the app version (Settings, "About" section) and your iPhone model. We aim to reply within a few days.
Your journal is stored only on your iPhone. If you use Ember on Apple Watch, the watch keeps only a service file for syncing with the iPhone. The app collects no data and does not send it to us or to anyone else; see the privacy policy for details.
The watch app shows today's count, your goal and the time since the last cigarette. Its "I smoked" button logs one cigarette you have smoked, and while the last entry can still be undone, an undo button appears next to it. The watch exchanges data only with the iPhone it is paired with. If an iPhone with a slash appears next to the count, the iPhone has not confirmed that entry yet: it is applied once the watch has passed it to the iPhone and Ember is open on the iPhone.
Settings, the "Data" section -> "Export to CSV". The file opens in the system share sheet - save it to Files or send it to yourself. It holds every smoking entry: the time, the "backdated" flag, and the reason.
Settings, the "Data" section -> "Export all data (JSON)". That is a single file with everything the app keeps about you: smoking entries, cravings you rode out, the wellbeing diary, your milestones, and your settings, including the reasons you wrote yourself. There is no import for that file - it exists as a readable safety copy, while the smoking log itself comes back through "Import from CSV". Keep the file somewhere you consider private: it contains your wellbeing notes in readable form.
A short optional check-in: a five-face mood scale, and behind "More" a checklist of common withdrawal symptoms and a free-text note. The "How are you feeling?" card appears on the Tracker tab; past check-ins live in the diary (the book icon on Tracker, or Settings, the "Wellbeing diary" section -> "Open diary"), where they can be edited or deleted. How often the app asks, and whether it also sends a notification, is set in the same section. Diary entries stay on the device and are not part of the CSV export.
There are two independent reminders: "Reminders" (a gentle once-a-day nudge to check in) and "Notify me" in the "Wellbeing diary" section. Check that the one you want is enabled in the app's Settings and that notifications for Ember are allowed in iOS Settings: if permission was denied, the app shows an "Open iOS Settings" button. If both are set to the same time and the diary frequency is "Daily" or "Weekly", the app deliberately sends the diary prompt only, so that two banners do not arrive in the same minute. With "Every other day" the prompts follow a rolling grid of dates, so this case is not suppressed: once every two days both notifications arrive. Move either time to always get both.
On the old device: Settings -> "Export to CSV", save the file to Files or iCloud Drive. On the new one: Settings -> "Import from CSV", pick that file - records are added, duplicates are skipped. The file holds your smoking log: the time, the "backdated" flag and the reason of every record. Settings (pack price, reduction plan), the wellbeing diary and the resisted-cravings journal are not in it: those go into the JSON export, which the app cannot read back, so settings have to be set again on the new device.
One caveat about reasons. The eight built-in reasons ("Stress", "Coffee" and the rest) carry over as they are. Reasons you created yourself are stored in the file as internal identifiers, not as labels. The new device does not have those identifiers yet, so those records appear as "Other" in the breakdowns and show no reason label in the History list. You can create your own reasons again in Settings -> "Reasons", but they will not re-attach to the old records: a new reason gets a new identifier. The records themselves come across in full - the time and the "backdated" flag are not lost.
Settings, the "Data" section -> "Erase smoking history". The app asks for confirmation and then removes every smoking entry. Your wellbeing diary, resisted cravings, milestones and settings stay - including the record of which milestones were already celebrated, so earning one again will not celebrate it a second time. This cannot be undone, so export first if you want a copy.
Delete the app from your iPhone - all of its data is removed from the iPhone with it, settings, diary and milestones included. If you use Ember on Apple Watch, the watch keeps only Ember's service file, and it goes away together with the watch app; you can remove the watch app from the watch, for example in the Watch app on your iPhone. Export first if you want a copy: erased data cannot be recovered.
