Mugi TCG - Looking for community feedback
Hi nakamas!
I'm the solo developer of Mugi TCG, an iOS OPTCG companion app I launched a month and a half ago (I know, another one).
I'm making this post now because I think this latest version I've shipped (12 so far) is in a good place. That said, I'm not gonna say it's the ultimate OPTCG app. There's still a lot to improve, add or change. That's why I'm here.
So let's get to the point: what can Mugi do? I'll break it down into 3 groups: card collection and price tracking, deck building and stats, and meta exploration.
Card Collection and Price Tracking
- Currently only includes English cards (nice start..). I'm working on adding the Japanese card catalog, but it'll take some time. As most of you know, since AAs in OPTCG don't have unique IDs, it's tricky to track or be sure you've got every available card. That's why I've added a way to report missing cards both in the app settings and on the Discord.
- Prices from both TCGPlayer and Cardmarket. You can check raw market prices and lowest listings in both marketplaces, along with a 14-day price history per card (will go up to 30 days in the future). In Settings you can pick your preferred marketplace to display and track prices. This setting also applies to scanner results. If there's any issue with a specific card, there's a "report card issue" option in every card detail view.
- A card scanner. I've seen a lot of disagreement on how scanners should work in this type of app. Some users prioritize speed and don't mind a second tap to pick the right variant, others want the scanner to never miss. In Mugi it's a mix of both: the scanner is fully on-device and private for speed, it identifies the card ID first, then uses OCR to try to detect the variant. If it passes a confidence threshold, you get the result directly. Otherwise, the manual selector pops up. The problem? It currently doesn't detect DON!s. That's something I'm working on.
- Custom Collections. Collections you can create to track or wishlist specific cards. I've also added a fixed collection called "All my cards" that shows every card you own. A few users had been asking for this.
Deck Building and Stats
- A deck builder with standard validation (deck size, rotations, banned cards and banned pairs)
- Missing card validation (warns you if you don't actually own cards in your decklist)
- Deck share image generator
- Deck proxies PDF generator, with a B&W option
- Deck stats: general stats plus per-leader stats (going 1st or 2nd)
Meta Exploration
- Meta decks by format
- Major CS tournament results including top 32 lists. You can add any of them to your decks in 1 tap.
My Roadmap
- Add Japanese cards with Cardmarket prices
- Improve the deck builder card filters with more gameplay-oriented ones
Sorry for the long text. I'd love to hear your feedback, positive but especially negative. That's what actually helps me prioritize what to improve.
