About YuniApp and Code Effects

Code Effects

Yuni tracks her cycle from your phone. Most cycle apps assume the person holding the phone is the one having the period. Yuni assumes you are the boyfriend or the husband. You enter her cycle dates once, and every morning Yuni tells you which phase she is likely in, what she may need, what to...

  • No-code rule builder
    Provides a visual, English-like rule editor that allows business users without programming skills to create and modify complex business rules and decision logic.
  • .NET integration
    Designed specifically for .NET environments, allowing seamless embedding into C# and VB.NET applications, which is beneficial for teams already invested in the Microsoft technology stack.
  • Rule compilation to native code
    Rules are compiled directly into .NET assemblies rather than interpreted at runtime, which can result in faster execution performance compared to some interpreted rule engines.
  • Customizable UI components
    Offers embeddable rule editor controls that can be styled and integrated into existing applications, giving developers flexibility in how end-users interact with the rule authoring interface.
  • Reduces developer dependency
    By enabling business analysts to author and update rules directly, it can reduce the need for constant developer involvement when business logic changes, potentially speeding up time-to-market for rule changes.

Possible disadvantages

  • Limited platform scope
    Being tightly coupled to the .NET ecosystem limits its usefulness for organizations using other technology stacks like Java, Python, or Node.js, reducing its overall market flexibility.
  • Learning curve for setup
    While the rule editor is designed for business users, the initial setup, integration, and configuration within a .NET application often requires significant developer expertise and time investment.
  • Niche market presence
    Compared to larger, more established business rules engines and decision automation platforms, Code Effects has a smaller user base and community, which can mean less third-party support, tutorials, and shared resources.
  • Pricing transparency
    Detailed pricing information is not always readily available publicly, which can make it harder for prospective customers to quickly assess cost-effectiveness compared to competitors.
  • Scalability for complex enterprise needs
    For very large-scale, multi-platform, or highly complex enterprise decisioning needs, it may lack some of the advanced features, integrations, and scalability options found in more comprehensive decision management suites.

Questions & Answers

As answered by people managing YuniApp and Code Effects.

What makes your product unique?

YuniApp's answer

Yuni makes the partner the primary user. You enter her cycle dates once on your own phone. Open it in the morning and it shows the phase she is likely in, plus what to do and what to avoid today. She installs nothing and shares no data.

Her dates stay on your device, with no account and no cloud, unless you switch on sync yourself.

Why should a person choose your product over its competitors?

YuniApp's answer

Flo, Clue and Cycles need her to install the app, track her own data, and switch on sharing. Most partners never get past the first step. Yuni needs your phone and one setup screen.

The trackers answer her question: when is my next period, when am I fertile. Yuni answers yours: what does she need from me today. Few apps in this category run on Apple Watch, and fewer work without an account

How would you describe the primary audience of your product?

YuniApp's answer

Boyfriends and husbands whose partner menstruates, who want to help and cannot tell what helps. Long-distance couples use it most, since you cannot read the room from another city. So do partners of someone with PMS or PMDD, where the bad days arrive on a schedule you can learn.

Yuni has a tracking mode for her too, so some couples run it on both phones and pair with one link.

What's the story behind your product?

YuniApp's answer

The founder kept having the same argument with his girlfriend. The trigger changed each time, and it kept landing in the same week of her cycle. He lined the fights up against the dates and could see them coming.

He wanted one thing on his home screen: a widget that told him how to behave today, before he said the wrong thing. Nothing like it existed, so he built it for himself. The widget turned into an app and shipped on the App Store in February 2026.

Which are the primary technologies used for building your product?

YuniApp's answer

iOS app: Swift and SwiftUI, iOS 17 or later. SwiftData for local storage, WidgetKit for home screen widgets, ActivityKit for Live Activities, HealthKit for optional Apple Health sync, and a watchOS app with three complication types.

Backend and web: TypeScript on Hono and Node, Postgres via Supabase with Drizzle, an Astro landing site, and a Vite plus React web app. Hosted on DigitalOcean App Platform.

Third party: Adapty for subscriptions, PostHog for product analytics, Sentry for crash reporting, Resend for email.

Who are some of the biggest customers of your product?

YuniApp's answer

  • Individuals. Yuni sells to people rather than companies, so there are no enterprise accounts or logos to list here
  • One plan covers one phone, normally the partner's
  • Couples who run both the supporting and the tracking mode need a plan on each phone
