Calendarly: Print Your Calendar on Your Lock Screen, the "At-a-Glance" Solution for iOS Users

2026-02-18 | ProductHunt | Official Site | App Store

Screenshot Analysis: Five different styles of lock screen calendar wallpapers, ranging from minimalist black-and-white to bright pink color schemes. Features include yearly dot views, monthly calendar views, and schedule card views. The design feels premium and integrates naturally with the iPhone lock screen clock. The fourth phone shows specific event details—"gym 10:00-11:00", "Work 12:00-13:30"—indicating it's not just a static calendar but can display specific events for the day.

30-Second Quick Judgment

What it does: Turns your calendar into a lock screen wallpaper so you can see today's schedule just by picking up your phone—no unlocking, no opening apps, and no widget configuration required.

Is it worth watching?: For average users, it's interesting but not an essential install; for indie developers, it's a great "small but beautiful" implementation reference. It has low technical barriers but clever product thinking. With only 1 vote on PH, it hasn't been discovered by the masses yet, or perhaps this category is simply very niche.

Three Questions That Matter

Is it for me?

Target User Persona:

• iPhone users (Android not supported)
• People with busy schedules and multiple meetings a day
• Those who hate unlocking their phone and opening a calendar app just to check their schedule
• Users who care about lock screen aesthetics and dislike the awkward "0 events" display of native iOS widgets

When would you use it?:

• Glancing at your phone before a meeting to confirm the next start time.
• Picking up your phone upon waking to see the day's plan.
• Simply wanting a beautiful, functional calendar wallpaper.
• Note: If you need cross-device sync or team collaboration, stick to Calendly/Cal.com.

Is it useful to me?

ROI Judgment: If you check your schedule more than 5 times a day and use an iPhone, there's no harm in trying the free version. Honestly, native widgets + the calendar app can solve this, but just not as "elegantly."

Is it buzzworthy?

The "Wow" Factor:

• The "seamlessness" of seeing your schedule just by lifting your phone is genuinely better than opening an app.
• The template designs are beautiful; some color schemes are more refined than native iOS lock screens.
• Runs entirely locally with no internet connection, providing peace of mind regarding privacy.

The Downside: The product is too new; the App Store lacks sufficient ratings and reviews. There's almost no user discussion on Twitter or Reddit. The name "Calendarly" is often treated as a typo for "Calendly" by search engines, making it hard to find real user feedback.

For Indie Developers

Tech Stack

Core Implementation

This isn't a WidgetKit app. The logic is clever: it reads local calendar data (EventKit), renders an image based on the user's chosen template, and then uses Apple Shortcuts to automatically set that image as the lock screen wallpaper. It updates automatically every day. Essentially, it's a "Calendar → Image Renderer + Wallpaper Auto-Setter."

Open Source Status

Calendarly itself is not open source. However, similar solutions exist on GitHub:

Difficulty to replicate: Low to Medium. An experienced iOS developer could build an MVP in 1-2 weeks. The core technical points are EventKit + Image Rendering + Shortcuts integration. The hard part isn't the tech; it's the template design and UX details.

Business Model

• Monetization: Freemium + Subscription/Lifetime
• Pricing: Pro $14.99/year, $34.99 Lifetime
• Zero Backend Cost: Pure client-side app, no server overhead, extremely high profit margins.

Platform Risk

High Risk. Apple has already enhanced lock screen customization in recent iOS versions. If Apple natively supports a "Calendar Wallpaper" feature in the future, this app loses its reason for being. However, Apple hasn't done this yet, providing a window of opportunity for third parties.

For Product Managers

Pain Point Analysis

• Problem Solved: Poor iOS lock screen schedule experience—native widgets are small, often show "No Upcoming Events," and don't support all-day event displays well.
• Pain Level: Medium. It's an "improvement" rather than a "necessity."

User Persona

• Core User: Busy iPhone users (business pros, students).
• Secondary User: People who love personalizing their lock screens.
• Scenario: Checking the schedule multiple times a day, seeking a way to see plans without unlocking.

Feature Breakdown

Competitor Comparison

Key Takeaways

1. Wallpaper as a Widget Alternative: Bypass WidgetKit limitations by using wallpaper rendering for larger information displays.
2. Privacy as a USP: Purely local, zero data upload—a significant advantage in a privacy-sensitive market.
3. Shortcuts Automation: Leverage native system automation to avoid the need for persistent background processes.

For Tech Bloggers

Founder Story

• Founder: Dmytro Katyukha
• Background: Based in Kyiv, Ukraine; CTO and Co-founder of CR&D, focusing on Odoo enterprise automation.
• Education: Master's in System Programming from the National Aviation University of Ukraine.
• Why build this?: A classic indie developer side project. While his main business is B2B, he builds consumer iOS tools on the side. He also released "Would You Rather? Hard Choices," suggesting a penchant for lightweight iOS experiments.

Controversies / Discussion Angles

• Naming Blunder: "Calendarly" is just one letter away from the world-famous "Calendly." This is a nightmare for SEO and brand recognition, often being flagged as a typo by Google.
• Platform Risk: Apple's continuous enhancement of lock screen customization is eating into the survival space of such apps.
• Wallpaper vs. Widget: Why is a wallpaper better than a widget for displaying a calendar? This is a great UX topic to explore.

Hype Data

• PH Ranking: 1 vote, virtually no reach yet.
• Twitter/X: No official account or user discussion found.
• Reddit: Zero discussion.
• App Store: Not enough ratings to display.

For Early Adopters

Pricing Analysis

Note: Competitor LockScreen Calendar Maker is significantly cheaper ($9.99/yr, $19.99 lifetime) and includes Lunar calendar and "Life Progress" views.

Getting Started

• Setup Time: 5-10 minutes
• Learning Curve: Low
• Steps:
  1. Download Calendarly from the App Store.
  2. Grant calendar access.
  3. Pick a template you like.
  4. Customize colors and layout.
  5. Follow prompts to set up the Apple Shortcuts automation.
  6. Done! Your wallpaper now updates daily.

Pitfalls and Precautions

1. Shortcuts Limitations: Apple Shortcuts aren't "instant"; wallpaper updates may lag. A meeting added mid-morning might not show up immediately.
2. iOS Requirements: Requires iOS 16.6+; older devices are not supported.
3. Home Screen Sync: Setting a lock screen wallpaper might affect your home screen wallpaper depending on your iOS focus/wallpaper settings.

Security and Privacy

• Privacy Policy: No accounts, no tracking, no cloud.
• Audit: No public audit, but local-only operation is the best privacy guarantee.

Alternatives

For Investors

Market Analysis

• Productivity App Market: 2024 revenue exceeded $30B, up 17.3% YoY.
• Lock Screen Sub-segment: No independent data; an extremely niche intersection (Calendar x Wallpaper x Lock Screen).
• Ceiling: This is not a category that will reach hundreds of millions in valuation.

Competitive Landscape

Timing Analysis

• Why now?: iOS 16 opened lock screen APIs, but native widgets remain limited, leaving room for third parties.
• Risk: Apple could introduce native calendar wallpapers at any time.
• Window: Estimated 1-2 years, depending on Apple's release cycle.

Team Background

• Founder: Dmytro Katyukha, Ukrainian developer.
• Core Team: 1 person (Indie side project).
• Track Record: Main business is CR&D (Odoo solutions); also built the "Would You Rather?" app.

Funding Status

• Funding: None.
• Investment Verdict: Not a VC target. It's a classic indie side project, perfect as a "small and beautiful" independent income stream.

Conclusion

One-Liner: A beautifully designed "Lock Screen Calendar Wallpaper" tool that solves a minor iOS pain point, but the niche is too small and platform risk too high for major commercial scaling. Best viewed as a technical reference for developers.
