About this app

Introducing "Ei Nano" - the ultimate healthcare app designed to meticulously track and manage your daily self-pleasure activities.

Wondering about your last session? The dynamic calendar view lets you quickly revisit past activities and better understand your unique cycle, optimizing your physical and mental well-being.

Let me also explain the features below.

Notes:
* Quickly jot down details about each session.
* Add personal notes to reflect on your experiences and feelings.

Stopwatch:
* You can use the stopwatch for recording.
* No matter how engrossed you become in self-pleasure, starting the stopwatch ensures you won't forget to record.

Calendar:
* You can toggle between statistics/analysis and the calendar view.
* In the calendar, you can view records for each month.

Periods:
* By turning on the feature in settings, you can register your periods.
* Based on recorded periods, it predicts the next period and ovulation day.
* You can check the correlation between self-pleasure and period days.

Share as an Image
* Each section of the statistics/analysis can be shared or sent as an image.
* Feel free to use it for posting on social media, etc.

Date range:
* You can change the period for analyzing statistics.
* Options include All time, Last 7 days, Last 30 days, Last 90 days, Last 180 days, Last 365 days, This year, and Last year.

Backup:
* Supports the built-in "Auto Backup" on Android devices (up to 25MB).
* Allows manual backup to Google Drive from within the app, with the option to restore as needed.

The following data is presented as statistics/analysis.

Last time & Biorhythm:
* You can check the date and time of the last self-pleasure session and its cycle in a line graph.
* Tap each marker on the line graph to check the index for that date.
* If you maintain self-pleasure once a day, the index is 1.00.
* For men, a Harvard University study found that engaging in self-pleasure more than 21 times a month lowers the risk of prostate cancer. With 21 times a month (or 5 times a week), the approximate index is around 0.72.
* The index can be used as a target of 0.72 or to track fluctuations in frequency when it temporarily increases or decreases.
* Unstable biorhythms might be a sign that your body and mind are not in a normal state. Understanding your biorhythm can help with health management.

Day of the week:
* You can check the statistics by day of the week.
* You can also see the total for weekdays and weekends.

Time of day:
* You can check statistics by time of day.
* Time periods are classified as morning, afternoon, evening, and night.

Duration:
* View the time spent on each session in minutes.
* Check the longest, shortest, and average times.
* Tap to see detailed records.

Top tags:
* Check the frequency of tags for each record in descending order.
* Tap each tag to view a list of records.
* Added tags can be edited or deleted later.
* The "Top tags" section appears only if there are tags set; if none, it will not be displayed.

Pornography & Pleasure Toys:
* Check usage statistics for each category.
* Tap an item to see records.

Orgasms:
* Check orgasm statistics during self-pleasure.
* Tap to see records.

Enjoy styles:

EDIT: Thank you for the quick response and promised fixes for my issues! Both are the mark of a good developer. 👍 EDIT 2: Okay, now what I'd like to see is a full export/backup that doesn't cost so much. Many other apps I use have that function for free, or at least have the premium or lifetime version for less than $25 USD. I really love this app and would happily pay for that kind of security for my data, but not that much!

Thanks for the great review! We'll increase the Notes limit to 1,000 characters. Please bear with us due to delays in the review process until the update is live. We'll also update the biorhythm explanation. For example, Harvard research suggests that having over 21 sessions per month can lower prostate cancer risk, with an index of "0.72".

Used old Ei Nano for over a month, really like it. Went to it's page to leave a review and request a feature to allow you to search your logged data by tags. I learned of this new version, so I installed it and exported my data from the other app. I was a bit disappointed that importing data is a premium feature... but I've enjoyed Ei Nano so far, so I got a week subscription for less than 2$. But then when trying to import the .csv it tells me "No Records". So I feel a bit scammed.

Update: The developer is actually great and fixed my only issue that was described below. Thanks man! The best, and especially most visually appealing, orgasm tracker on Android, at least that I've found. I just wish the developer would put in a feature to import the data from the original Ei Nano app into this deluxe edition.
