    I need help changing the visible name of an Android application that is already installed (or will be installed shortly). I will supply the current package and the existing project files; the new label itself is still undecided, so I’m counting on you to make the switch once I confirm the wording. The task is limited to the app-name label only—no package-ID or code-level refactoring is required. I will just get the apk file from you and i will reinstall it to the device. Or you will just rename the application in my device.

    I’m running the Prestige theme on Shopify and the cart has started misbehaving on mobile—both iOS and Android. Whenever a shopper adds a product, the cart grabs the previous item instead, so the cart is always one step behind. Swiping through product images or switching variations triggers a “SyntaxError: The string did not match the expected pattern,” blocking the add-to-cart action entirely. Removing items or updating quantities fails as well. Key pain points you’ll tackle: • Adding products, removing items, and changing variations must work reliably on mobile. • The cart should display the correct, current product every time. • No more SyntaxError on variant change.

    One gallery page on my Squarespace site (7.1) needs a quick mobile-only tweak. Right now the carousel looks great on desktop, but on phones each slide expands to the full height of the hero image above it. I simply want the carousel to disappear on small screens and have every shot flow in a clean vertical stack instead. Here are the specifics you can rely on: • Format: vertical stack only; no swipe or horizontal scroll • Sizing: keep every image at the same displayed height while preserving its native aspect ratio—portrait files should not be forced to full-width stretch • Content: no captions or overlays, just the images themselves • Scope: one page, no other site areas touched; desktop experience must remain exactly as is I’m comfortable with c...

    I need a developer who can build a clean, stable Android application that lets users sit for fully-timed mock exams.

    Don't bid if there's no demo. I need full source-code replicas of the slot titles released by Pragmatic Play. Every visual, audio, math model and game mechanic must match the originals exactly, including bonus rounds and free-spins sequences, while delivering the same high RTP percentages players expect from the provider. The build has to sit inside a back-office that lets me create, credit and deduct balances for whoever plays i want login screen, review detailed game logs and change RTP settings per title. An RNG that can be certified is essential, as is clean, well-documented code that my own dev team can later extend. Progressive jackpots are not required at this stage, but keep the architecture flexible so we can bolt that on later without a rewrite. Feel free to use any p...
