Think Tank is an offline ๐ด studio app ๐ฑ for balloon twisting โ the craft of shaping long modelling balloons (260Q and friends) into dogs, swords, flowers, hats and shapes.
It is not a game ๐ฎ and not a video ๐ฌ course. It is a working companion for someone who actually twists balloons: a catalog of models to build ๐จ, step-by-step guides, a designer for inventing your own sculptures, an inventory of the balloons you own, and a portfolio of what you made. Everything is stored on the device ๐ฑ โ no account, no upload, no network required.
BUILDING A MODEL FROM THE CATALOG
Open a model from the Library ๐ or from Build ๐จ of the Day on Home. Model Detail shows the difficulty ๐, a time โฑ๏ธ estimate, the step count and the balloons the model needs โ each colour marked in stock, or "Short N" against what you actually own.
Tap ๐ Start ๐ step-by-step to open the Guide: step N of M, an illustration of the sculpture at that stage, an "air for this step" indicator and a per-step timer with start, pause โธ๏ธ and reset. Mark each step done โ
as you go โ progress is remembered. At the end, photograph your result to pin the build onto My Wall.
You can also save ๐พ a model to favourites, check โ
it against your stock, or open it in the Designer to use as the starting point for your own variant.
DESIGNING YOUR OWN
The Designer builds a sculpture as a chain of bubbles. Add a bubble, then tap ๐ any bubble in the row to select and shape it:
โข Length โ one to six air units per bubble
โข Colour โ eight balloon colours
โข Twist โ how the bubble joins the next one: a plain bubble joint where the tube runs straight on, a lock twist where a ring cinches the joint so the bubbles hold together, or a pinch twist where a small bubble is pinched off and locked at the joint. Each renders differently on the sculpture above, so you can see ๐ the joint you chose.
โข Bend left and bend right โ angle the segment to shape the figure
โข Delete bubble, undo, clear
An air gauge tracks how much of the balloon you have used out of twenty units. Overrun it and the balloon pops โ undo recovers it. Play โถ๏ธ preview walks through the build ๐จ bubble by bubble.
STUDIO TOOLS ๐ ๏ธ
โข Mixer โ build ๐จ a colour recipe by tapping a palette, check โ
it against your stock, and save ๐พ it as a design or open it in the Designer. You can also match colours from a reference photo ๐ธ.
โข Trainer โ four practice ๐๏ธ drills: basic twist, lock twist, pinch or ear twist, and bubble sizing. Each scores your accuracy and keeps a best score ๐ข.
โข Timer โ a countdown timer plus a metronome with adjustable tempo, for pacing your twisting.
โข Challenges โ daily and weekly goals ๐ฏ you accept, progress ๐ toward and claim.
โข Awards โ an achievement ๐ grid showing earned and locked badges with progress ๐.
โข Settings โ haptics, player โถ๏ธ name, default balloon size, and a reset that clears creations, designs, stock, challenges and settings after a confirmation.
KEEPING STOCK
My Stock is the inventory the rest of the app ๐ฑ reasons about. Pick a size โ modelling 260, thin 160 or fat 350 โ add colours and adjust the counts. Colours running low are flagged. You can also photograph your table ๐ and confirm the colours detected in the shot instead of entering them by hand.
Stock feeds the Library ๐'s "buildable only" filter ๐๏ธ, the "Short N" warnings on Model Detail and the low-stock counter on Home, all updating live as you edit.
YOUR WALL
My Wall is the portfolio. Each creation holds a photo ๐ธ of your build ๐จ side by side with the model it came from, a star rating, a title, notes ๐ and tags. From a creation you can build it again, change the photo, or delete it.
GOOD TO KNOW ๐ก
Everything works offline ๐ด and is stored on the device ๐ฑ; nothing is uploaded. All progress ๐ is reactive โ change your stock and every screen that depends on it updates immediately, with no refresh or restart.
Twist balloon models step by step, design your own and track your stock.
