Cosplanner is gone. Now what?

If you've been using Cosplanner to track your builds, you already know something's wrong. The Android version was pulled from Google Play in January 2025. The iOS app hasn't been updated since June 2020. The web app at cosplanner.net? Login is broken, account creation throws errors, and the developer hasn't responded to support requests in over a year.

It's dead. Not "on hiatus," not "being reworked." Dead.

Which is a shame, because Cosplanner did things right for its time. Project-level cost tracking, progress percentages, a clean list of what to buy vs. what to make. A lot of cosplayers built their first five or ten costumes with it. I did.

But now you're stuck with an app that crashes when you try to back up your data, a 5-photo limit per project (absurd for a visual hobby), and 25 items max on your buy/make list. If you switched phones recently, your data might already be gone.

Here are five alternatives that actually work today, with honest takes on what each one does well and where it falls short.

Quick verdict

Short on time? Here's who should use what:

• Want the closest Cosplanner replacement? Cosplai or Cosplan. Both have project tracking, budget, and mobile apps.
• Prefer web over apps? Cosflowy or Costumary. No app store dependency, works on any device.
• Need the best reference image organization? Costumary or Milanote. Both handle visual references well, but Milanote's free tier is brutal.
• Want social features and event discovery? Cosplan or Cosplai. Both have community feeds and convention listings.
• Tightest budget? Cosgear. Completely free with unlimited storage.

1. Cosplai

• Platforms: iOS, Android (no web app)
• Price: Free (10 projects, 3 events) / Pro $9.99/mo or $59.99/yr
• Best for: Cosplayers who want everything in one mobile app

Cosplai is the newest entrant and the most ambitious. It tries to be the everything-app for cosplay: project management, budget tracking, reference images, convention discovery, social connections, countdown timers, and offline access.

What it does well:

Multi-status task tracking is genuinely useful. You can mark items as To Buy, To Make, Ordered, or Finished, and the budget rolls up automatically from individual items to a project summary. That's the workflow Cosplanner got right and most alternatives skip.

Convention discovery with venue search is a nice touch. You can browse events, add them to your calendar, and link costumes to specific cons.

Where it falls short:

Mobile only. No web version means you can't plan on a laptop with a big screen, which matters when you're juggling reference images, material lists, and a budget spreadsheet side by side. If you do most of your planning at a desk, this is a real limitation.

Pro pricing is the highest in the category at $60/year. The free tier caps you at 10 projects and 3 events, which is fine for casual cosplayers but tight if you're building for multiple cons.

They also published a "Best Cosplay Planning Apps in 2026" blog post where they ranked themselves #1, which tells you everything about their marketing approach. The app is solid though.

2. Cosplan

• Platforms: iOS, Android, Web (pro.cosplan.app)
• Price: Free core / Premium with advanced features (price not listed publicly)
• Best for: Social cosplayers who want to share progress and discover events

Cosplan calls itself "The First Social Network for Cosplayers" and that's an accurate description of its priorities. It's planning-capable but community-first.

What it does well:

Cross-platform including a web app, which is increasingly rare. 25,000+ cosplayers use it, so there's an actual community to connect with. Photoshoot documentation lets you credit photographers, locations, and other cosplayers in your shoot, which is a thoughtful feature the community actually wants.

Event discovery for conventions, workshops, and meetups is built in. Inventory management covers costumes, accessories, and materials.

Where it falls short:

Because it's social-first, the actual build planning tools feel like they come second. Budget tracking exists but isn't the focus. If you want a deep materials list with status tracking, cost alternatives, and store links per item, you'll outgrow it quickly.

Some users mention language support limitations depending on your region.

3. Cosgear

• Platforms: iOS, Android
• Price: Free with unlimited storage
• Best for: Budget-conscious builders who want tutorials alongside planning

Cosgear is the only completely free option with no hidden limits. No premium tier, no paywalled features, no storage caps. That alone makes it worth trying.

What it does well:

Built-in step-by-step guides and cosplay tutorials. Free patterns and 3D print files. If you're a beginner who wants planning and learning in the same place, Cosgear is genuinely useful. Task management with sections and sub-tasks works well for breaking a build into pieces.

Shopping lists with budget management cover the basics Cosplanner handled.

Where it falls short:

It's not a complete project management solution. No reference image organization, limited timeline features, and no convention-specific planning (packing lists, event linking). Multiple reviewers say it "works best paired with another tool," which kind of defeats the purpose of a dedicated app.

The Progress Hype Feed is a social feature that some people love and others find distracting when they're trying to focus on planning.

4. Cosflowy

• Platforms: Web (desktop-optimized), mobile PWA
• Price: Free with premium tier
• Best for: Detail-oriented builders who think in workflow steps

Cosflowy takes a unique approach: instead of organizing by project, it organizes by element. Each costume piece gets its own workflow with materials, expenses, tasks, and progress tracking. If you think about builds as a sequence of steps rather than a list of components, this clicks immediately.

What it does well:

The element-by-element breakdown is genuinely different from every other app here. Reference image gallery with collections, calendar view for conventions, budget planning with a visual spending overview. The interface is clean and modern.

Web-first means no app store dependency. It works on any device with a browser, and there's a PWA for mobile if you want a home screen shortcut.

Where it falls short:

Built by a solo developer (Leo, who's also a convention photographer). That's not a criticism of quality, but it does mean development pace is slower and the user base is smaller. The workflow format can feel inflexible if your build process isn't linear. Not a native mobile app, so the PWA experience on phones isn't as smooth as a dedicated app.

Budget tracking is described as secondary to the workflow management, so if budget is your main concern, look elsewhere.

5. Costumary

• Platforms: Web
• Price: Free (2 active projects) / Paid $9/mo (unlimited)
• Best for: Builders who want references, materials, budget, timeline, and build log in one connected workspace

Full disclosure: this is us. I'm going to be honest about what we do well and where we're still catching up.

What we do well:

Everything lives in one project workspace: reference board, materials list with status tracking (need, ordered, arrived, owned, tested, used), budget that auto-calculates from your materials, timeline with cosplay-specific phases (patterning, construction, finishing, fitting, wear test, packing), and a build log with structured entries for what worked, what failed, and next steps.

The build assistant knows your project. It reads your materials, your budget, your timeline, and your recent build log entries before answering. Ask it "what should I work on next" and it'll actually reference your specific deadline and unfinished milestones, not give you a generic answer.

The reference board handles unlimited uploads on the paid tier (200 per project), which is a direct response to Cosplanner's 5-photo limit.

We also built a free Craft Build Cost Estimator that works without an account. It has pre-loaded templates for armor, sewn, and mixed builds with real material prices, a safety buffer slider, and a breakdown of where the money goes. If you just want a quick budget check before committing to a build, it's there.

Where we're still catching up:

No native mobile app yet. The web app is responsive, but you won't find us in the App Store or Google Play right now. No social features, no event discovery, no community feed. We're focused on the build planning experience first.

The free tier gives you two active projects, which covers most casual builders. If you're juggling three or more concurrent builds, you'll want the paid plan.

Comparison table

What about Milanote?

Milanote deserves a mention because cosplayers love it for reference boards. It's a general creative tool, not cosplay-specific, but the visual mood board experience is best-in-class. Drag and drop images, web clipper extension, color swatches, and a clean interface.

The problem is the free tier: 100 cards total. That's notes, images, and links combined. One armor build with detailed references can burn through 50 cards easily. The paid tier is $9.99/mo (annual) or $12.50/mo, and you're paying for a mood board with no budget tracking, no materials list, no timeline, and no progress tracking.

If you're already paying for Milanote and love it, pair it with one of the apps above for the planning side. But if you're starting fresh, a dedicated cosplay tool covers both references and planning.

What about Notion or Trello?

Notion is infinitely flexible, which is both its strength and its biggest problem. You can build a cosplay planner in Notion (there are templates on the marketplace for $5-15), but you're spending hours setting up databases, formulas, and relations instead of actually building your costume. The mobile app also gets sluggish with image-heavy content, and reference-heavy cosplay boards have a lot of images.

Trello works for group cosplay coordination but has no budget tracking without Power-Ups and no cosplay-specific features. It's a generic project board.

Both are fine if you've already invested time building your system. Neither is worth starting from scratch in 2026 when dedicated tools exist.
