The D&E Fragrance app
Everything you need to set up your diffuser, control it from your iPhone or Android phone, and keep your home beautifully scented.
1Before you start
You'll need:
- your D&E Fragrance diffuser, plugged in, with fragrance oil in the bottle
- an iPhone or Android phone with Bluetooth turned on
- the free D&E Fragrance app from the App Store or Google Play
The app talks to your diffuser directly over Bluetooth, so you don't need Wi-Fi or an account.
A diffuser can only connect to one app at a time. If you've used another app with your diffuser, close it fully first: open your phone's recent apps screen (on most phones, swipe up from the bottom and hold), then swipe the app away.
2Connect your diffuser
Turn on Bluetooth search mode
- Make sure the diffuser is plugged in.
- Tap the on/off button on the diffuser 3 times. This turns on Bluetooth search mode, so your phone can find it.
Add it in the app
- Open the D&E Fragrance app and tap Add Diffuser (or + in the top corner).
- When asked, tap Allow so the app can use Bluetooth. On Android this may be called Nearby devices.
- Your diffuser appears under Nearby devices. The strongest signal is at the top. Tap it.
- Give it a name and choose its room, for example "Living Room". Then tap Save.
- The app connects and syncs the diffuser's clock. When the status shows Connected, you're ready.
Tap the on/off button 3 times again, keep your phone within a couple of metres, then tap Scan. See Troubleshooting for more.
3Turn it on and off
Tap a diffuser on the home screen to open its controls, then tap the large round power button.
- Gold and glowing: the diffuser is on.
- Dark with a gold outline: it's off.
Under the button you'll see what the diffuser is doing, for example Diffusing.
When the diffuser is on, it follows its schedule: it sprays only on the days and between the times you've set. If it's on but not spraying, check your schedule.
4Choose the intensity
Your diffuser releases fragrance in short bursts, with a rest in between. Under Intensity, choose one of four levels:
| Level | Spray | Rest | Good for |
|---|---|---|---|
| Light | 10 seconds | 3 minutes | Bedrooms and small rooms |
| Medium | 10 seconds | 2 minutes | Everyday living spaces |
| Strong | 20 seconds | 1½ minutes | Larger rooms and open-plan spaces |
| Max | 30 seconds | 1 minute | Big spaces, or when guests arrive |
For your own timing, use the − and + buttons next to Spray and Rest, then tap Apply custom timing.
A stronger setting uses fragrance faster. The app updates your days-until-refill estimate as soon as you change the level.
5Set a schedule
A schedule tells the diffuser when to scent your home, such as weekday mornings or every evening.
- Open your diffuser and tap Schedules.
- Tap + to add a schedule, or tap your existing one to change it.
- Tap the days you want. Gold days are on.
- Set the Start and End times.
- Choose the intensity for this schedule.
- Tap Save. The schedule is sent to your diffuser straight away.
Your diffuser holds one schedule. It can't run past midnight, so set the end time to 23:59 at the latest. The schedule is stored in the diffuser itself, so it keeps running when your phone is away or the app is closed.
Keep the clock right
The app sets the diffuser's clock every time it connects. If the times ever look off, for example after the clocks change, open the diffuser and tap Sync clock.
6Fragrance level and refills
The gold bottle on the control screen shows roughly how much fragrance is left, and about how many days it will last at your current settings.
Log each refill
- After filling the bottle, tap Refilled.
- Choose Added 50 ml, Added 100 ml or Fully refilled (200 ml).
- The first time, tap Allow so the app can remind you before you run out.
Reorder reminders
When you're down to about 7 days of fragrance, your phone shows a reminder, even if the app is closed. Tap it to go straight to our shop. An Order more fragrance button also appears under the bottle.
The app works out usage from your intensity and schedule, counting from the last refill you logged. It's an estimate, so for the best results tap Fully refilled each time you top up. If the diffuser is switched off for a while, logging your next refill corrects the count.
Using a different bottle size? Open the diffuser, tap Edit, and change Fragrance bottle.
7More diffusers and rooms
- Add another diffuser: put it in Bluetooth search mode (tap its on/off button 3 times), then tap + on the home screen.
- Rename it or change its room: open the diffuser and tap Edit.
- Remove a diffuser: open it, scroll down and tap Remove Diffuser. You can also swipe left on it on the home screen.
The home screen groups your diffusers by room, so you can see your whole home at a glance.
8Troubleshooting
The app can't find my diffuser
Work through these in order:
- Tap the diffuser's on/off button 3 times to turn Bluetooth search mode on again.
- Fully close any other diffuser app on your phone or anyone else's nearby. The diffuser can only connect to one at a time.
- Check Bluetooth is on. iPhone: Settings › Bluetooth. Android: swipe down from the top of the screen and check the Bluetooth tile is on.
- Make sure the app is allowed to use Bluetooth. iPhone: Settings › Privacy & Security › Bluetooth, then turn on D&E Fragrance. Android: Settings › Apps › D&E Fragrance › Permissions, then allow Nearby devices.
- Move your phone closer to the diffuser and tap Scan.
- Unplug the diffuser for 10 seconds, plug it back in, and try again.
It says "Not connected" or "Couldn't connect"
Open the diffuser, scroll to Device, and tap Connect. If that doesn't work, close any other diffuser apps, turn your phone's Bluetooth off and on again, and try again. As a last resort, remove the diffuser from the app and add it again.
The diffuser is on but not spraying
It only sprays during its schedule. Check that today is one of the selected days and the current time is between the start and end times. Then tap Sync clock. Also check there's fragrance in the bottle.
I'm not getting reorder reminders
Make sure notifications are allowed. iPhone: Settings › Notifications › D&E Fragrance, then turn on Allow Notifications. Android: Settings › Apps › D&E Fragrance › Notifications, then turn them on. Reminders start counting from your last logged refill, so tap Refilled after topping up.
The days-until-refill estimate seems wrong
Tap Refilled › Fully refilled next time you fill the bottle, so the app starts from an accurate level. Also check the bottle size under Edit matches your diffuser.
9Questions
Do I need Wi-Fi or an account?
No. The app connects to your diffuser directly over Bluetooth. There's nothing to sign up for.
Does the diffuser keep working when my phone is away?
Yes. Your schedule and intensity are saved in the diffuser, so it carries on as normal. You only need your phone nearby to change settings.
Can more than one person control the diffuser?
Yes, anyone with the app can add the same diffuser, on iPhone or Android, but only one phone can be connected at a time. If someone else is connected, ask them to close the app.
What does the app do with my information?
Nothing leaves your phone. Your diffusers, schedules and refill history are stored only on your phone, and the app doesn't collect or share any personal data.
Is there an Android app?
Yes. The D&E Fragrance app is free on both iPhone and Android. Download it from the App Store or Google Play.
