We released an App that helps the fruit growth of tomatoes by using the vibration function of the iPhone device.

-- What kind of App is SmartBumblebee? --

● This is an application that helps the fruit growth of tomatoes by using the vibration function of the iPhone device.
● This app helps pollinating tomato flowers by replacing the bumblebees action of vibrating tomato flowers and collecting pollen.
● Users can save the information regarding usage to manage the work history and to keep track for future improvement of the pollination process.
*this app can also be used to pollinate other vegetables (ie. eggplants and peppers).

-- Who is this app useful for? --

People who want to:
● grow tomatoes on a small scale.
● ensure effective fruit growth of tomatoes, to improve the yield and fruit quality.
● produce tomatoes without using chemicals.
● keep a history of work and manage fruit growth efficiently.

-- How to use this App--

【Pollination process by device vibration function】
When you find a flower that is in full bloom, touch the device at the base stem of the flower bunch to vibrate it entirely.

↓This site also explains in detail how to use this app.

【Characteristics of each vibration mode】
As a method of vibrating the device, (1) 1-shot mode and (2) hold mode can be used.

(1) 1-shot mode :
● Tap the button to vibrate the device once.
● When vibrated, the gauge inside the button advances and reset when not in use.
● If you over-vibrate continuously, it will lock for 10 seconds to limit excessive continuous use to reduce the burden on the device.

(2) hold mode :
● Slide the button up to turn hold mode on and vibrate continuously.
● This mode also supports avoiding overuse of the ‘1-shot function’ which locks it.

【How to improve pollination effect】

(1) Check the vibration characteristics of the device used :
● Check which part of your phone vibrates the strongest.
● Touch the target and vibrate it using this part of the phone.

(2) Check the growing condition :
● If the tomatoes grow poorly, don’t pollinate the flowers because they may not grow.
● Take necessary care to ensure good growth before pollination.

(3) Flower condition that needs to be processed :
● Pollination process starts when the flower at the root is available and continues at a certain period until the flower at the tip has completed pollination.

(4) Weather conditions and time of day for pollination:
● In seasons with a minimum temperature of 10°C or higher and a maximum temperature of 35°C or lower.
● Use on sunny or cloudy weather, avoid processing on rainy days.
● More effective in the mornings.

(5) How to check if the fruit has settled after processing :
● When the fruit set is complete, the ovary becomes glossy and swelling (7 mm or more).
● The estimated period from after treatment (flowering) to confirmation of fruit set :
- Summer (daily average temperature is 20 ° C or higher) → After treatment: 4 to 6 days.
- Spring and Autumn (daily average temperature is 10 to 20 ° C) → After treatment: 5 to 7 days.

【Addition and display of pollination work history】

(1) Add history
The following information can be saved as a history :
● Date and time of use.
● Image of flowers when using.
● A number of vibrations.
● Extra notes.

(2) View history
● Display in graph and list format :
- Display the saved history in list format.
- Display the number of vibrations on each day in a bar graph format.

● Calendar format :
- Days with history are marked on the calendar.
- Displays the history contents for each day.

【App settings on the settings screen】
● Camera function usage permission setting.
● Turning the display upside down the display.
● Language settings.
● Hide ads (Paid service of $0.99).

-- Please take note: --

● This app does not guarantee pollination or fruit growth of plants (e.g.tomatoes eggplants and peppers).
● The app developer is not responsible for any problems related to misuse of this application.
