Nineish Months: A Friendly, Secure Space for Your Pregnancy Journey Nineish Months is a simple, beautiful, week-by-week pregnancy tracker that does things a little differently. Most apps in this space ask for your email, your personal details, and eventually, your data. I built Nineish Months for parents who want a calm, friendly place to watch their baby grow without having to worry about where their private health information is going. The most important thing to know is that Nineish Months collects zero data from you. We donโ€™t use external servers, we donโ€™t ask you to create an account, and we donโ€™t track your personal information. Everything you logโ€”from your symptoms and moods to those first little kicksโ€”stays exactly where it belongs: on your own phone. Because your data never leaves your device, it is physically impossible for it to be sold, shared, or leaked. Itโ€™s security you can actually trust, simply because the data stays in your hands. Aside from the focus on security, the app is designed to be a peaceful, thoughtful companion. Each week, youโ€™ll find updates on your babyโ€™s development and insights into the changes happening in your own body. The interface is clean and intentional, focusing on the milestones that truly matter without the noise of endless notifications or unnecessary features. Whether you are a first-time parent or just looking for a more secure, quiet way to track your next pregnancy, Nineish Months offers a friendly space to focus on whatโ€™s important. Itโ€™s easy to use, beautiful to look at, and respects your privacy from the very first day.

Nineish Months features and specs

  • Focused Pregnancy Content
    The platform appears to center specifically on pregnancy and the journey through roughly nine months, allowing for tailored, relevant content rather than generic parenting information.
  • Relatable Framing
    The 'nineish' branding suggests a realistic, less clinical approach to pregnancy timing and milestones, which may resonate with users who appreciate a more approachable, less rigid tone.
  • Niche Community Potential
    By concentrating on a specific life stage, the site can foster a community of users going through similar experiences at the same time, which can be valuable for peer support.
  • Simple Value Proposition
    A narrowly scoped website is often easier for new users to understand quickly, since the purpose and target audience are clear from the name and framing alone.
  • Potential for Personalization
    Sites built around a specific journey like pregnancy often include week-by-week or stage-based content, which can make information feel personalized and timely for expecting parents.

Possible disadvantages of Nineish Months

  • Limited Public Information
    Without extensive publicly available details, it's difficult to fully assess the site's features, credibility, medical accuracy, or overall user experience.
  • Uncertain Content Depth
    It's unclear whether the site offers in-depth, expert-reviewed medical content or more surface-level lifestyle information, which could be a drawback for users seeking detailed clinical guidance.
  • Possible Narrow Scope
    Focusing exclusively on pregnancy may limit usefulness for users seeking broader parenting resources once the baby arrives, requiring them to switch to other platforms.
  • Unknown Monetization Model
    If the site relies on ads, sponsored content, or product recommendations, this could affect the objectivity or trustworthiness of the information provided.
  • Competition from Established Platforms
    Larger, more established pregnancy and parenting sites with more resources, medical reviews, and community features may make it harder for a niche site to stand out or provide comparable depth.

assertpy features and specs

  • Fluent API
    Assertpy offers a fluent API that makes assertions more readable and expressive, enabling developers to write assertions in a natural language style that is easy to understand.
  • Chainable Assertions
    It allows for chainable assertions, enabling multiple checks to be performed in a single line of code, thereby reducing verbosity and enhancing clarity.
  • Comprehensive Assertion Methods
    The library provides a wide range of built-in assertion methods, catering to various types of data validations, such as checking for size, type, value, and more.
  • Extensibility
    Assertpy supports extending its functionality by defining custom assertions, allowing developers to tailor it to their specific needs.
  • Pythonic
    Designed with Pythonic principles in mind, Assertpy fits seamlessly into Python projects, enabling idiomatic and consistent code style.

Possible disadvantages of assertpy

  • Learning Curve
    Developers new to the library may encounter a learning curve due to the distinct approach of using fluent and chainable assertions as opposed to traditional methods.
  • Limited by Python Version
    The library may have limitations in terms of compatibility with older versions of Python, requiring users to ensure their environment is up-to-date.
  • Performance Overhead
    The additional abstraction layer introduced by a fluent interface might introduce some performance overhead, especially in performance-critical or resource-constrained environments.
  • Less Community Support
    Compared to more established testing libraries, Assertpy might have less community support and fewer resources available for resolving issues or getting help.
  • Dependency Management
    Using a third-party library introduces additional dependencies to manage, which could complicate project maintenance and compatibility.

Questions & Answers

As answered by people managing Nineish Months and assertpy.

What makes your product unique?

Nineish Months's answer

What really sets Nineish Months apart is that itโ€™s built on a foundation of "Privacy by Design." While most pregnancy apps are built to collect and monetize your health data, Nineish Months is built to protect it. We don't have servers, we don't require accounts, and we never see your information. Itโ€™s a rare, truly private space that focuses entirely on the babyโ€™s growth and the motherโ€™s well-being, rather than on data collection.

Why should a person choose your product over its competitors?

Nineish Months's answer

A person should choose Nineish Months if they want peace of mind. Most big-name competitors track your every move and sell that data to advertisers. With Nineish Months, you get a premium, beautiful, week-by-week experience with the absolute certainty that your personal health journey stays on your own phone. Itโ€™s the right choice for anyone who wants an elegant tracker without the "creepy" factor of being followed across the web.

How would you describe the primary audience of your product?

Nineish Months's answer

Our primary audience is the modern, security-conscious parent. These are people who appreciate clean, thoughtful design and want to stay informed about their baby's development, but are also deeply aware of digital privacy. They are often looking for an alternative to "Big Tech" health apps and prefer supporting independent developers who prioritize ethics and user safety over profit.

What's the story behind your product?

Nineish Months's answer

Nineish Months was born out of a desire for a "quieter" and safer pregnancy experience. As an indie developer, I noticed that the most popular pregnancy apps were becoming increasingly cluttered and invasive regarding user data. I wanted to build something that I would actually want to useโ€”an app that felt like a supportive companion, looked beautiful, and treated user privacy as a human right rather than an afterthought.

Which are the primary technologies used for building your product?

Nineish Months's answer

The app is built natively for the Apple ecosystem using xcode, which allows for a fluid, modern, and highly responsive user interface. To ensure maximum security, we use local-on-device storage rather than cloud databases. This technical choice ensures that even the developer cannot access user data, as there is no central server to store it.

Who are some of the biggest customers of your product?

Nineish Months's answer

Our "customers" aren't corporations; they are families and individuals who value their digital sovereignty. Expectant parents looking for a private way to track their first pregnancy. Privacy-conscious families who want to keep their health data off the cloud. Minimalist users who prefer a clean, focused, and ad-free experience. Tech-savvy parents who prioritize "Privacy by Design" software.
