We want to develope an iphone app similar to our GoCanvas app that incorporates AI for job inspection reports. We will start with daily inspection reports and then create inspection and testing reports. We have dozens of existing reports that can be reduced to only a few with drop down options. I want field techs to take photos and dictate observations. AI should then draft a report to be saved in our Dropbox. I have attached one sample report. The main drawback to GoCanvas is once report is submitted for review, we are limited and no new sections or photos can be added. Also, some pages are very busy and some nearly blank, so appearance can be improved. Some basic construction knowledge is helpful.

I currently have a digital sticker app called, Pixel Parade App which is "supposed" to be available on iTunes and google play - it features in app purchases of various digital sticker collections. The current developers cannot service my app due to internal reasons I was told bandwidth issues. I have had nothing but problems with this development team for many years trying to get this app to the market place. I need someone that can maintain this app so it is available and working as well as update the app as needed with additional features in the future. I am a designer and not a coder - I believe the app was created with Flutter. I could be wrong.

About HeyCity HeyCity is a live iOS app (React Native / Expo) that turns city-council, planning-commission, and school-board meetings into short, fact-checked summaries for residents. It's an independent civic-information product — credibility is everything to us. The app's structure and our "HeyCity" wordmark are set; we're hiring for a focused visual refresh of specific assets, not a full app redesign. Design direction (please read — this is the heart of the brief) Because we publish civic information people make decisions on, the aesthetic needs to feel trustworthy and credible — clear, calm, well-crafted, never gimmicky. But trustworthy must not mean dull, grey, or corporate. We want it to stay warm, vibrant, and approachable — confident use of color that invites everyday residents in. Think "respected local newsroom that's actually pleasant to use," not "government PDF" and not "playful consumer toy." Striking that balance — authoritative and colorful — is the core of this engagement. Scope of work 1. The app icon — our flagship mark. This will be THE app icon: the single most-seen, most important piece of our brand, and the first thing a user taps on their home screen. The current icon is a colorful city-buildings collage (attached: city-collage-app-icon.png) — treat it as a starting point, not a constraint. We want something genuinely iconic, instantly recognizable, and memorable at a glance — you have real creative latitude here, and it does not have to remain a literal city collage. Deliver as one universal icon at every iOS + Android size (app icon, adaptive-icon foreground, splash) — it must hold up at the smallest sizes. 2. Category / topic icon set (11 icons). Redesign our meeting-topic icons: Budget/Cost, Transportation, Schools, Public Safety, Housing & Development, Environment, Business & Economy, Policy & Governance, Community, Infrastructure, Personnel/Staffing. Hard requirement: each must read clearly both large (~72px Explore tiles) and small (~18px badges on content cards) — see the attached contact sheet showing how our current traced-silhouette icons lose legibility at 18px. We need a cohesive, simple icon system that survives at tiny sizes and is instantly distinguishable from one another. 3. Onboarding / intro screens. Redesign the first-run intro flow (a few screens) — visuals, layout, and illustration style that set the trustworthy-yet-colorful tone from the first launch. (Current screenshots attached.) 4. Podcast cover art. A single, universal cover used across all our shows (attached: collage-mark.png + sample-podcast-cover.jpg for the current look). Square, scaling from ~40px in-app up to 3000×3000 for Apple Podcasts / Spotify. It should feel like the same brand family as the app icon and wordmark. ▎ Everything is universal — no per-city variants. A single app icon and a ▎ single podcast cover, used everywhere. They (and the wordmark) should read ▎ as one coherent brand family. What stays The "HeyCity" wordmark/logo stays for in-app and wordmark use — design to complement it. The app icon (item 1) is a separate, flagship mark and is fully open to reinvention. Deliverables - Figma source for all work. - One universal app icon as layered source + the full iOS + Android icon/splash size set (PNG) — no per-city variants. - All 11 category icons exported as SVG (we render them as in-app SVG), tuned for both sizes. - Onboarding screens as Figma frames + exported assets/illustrations. - One universal podcast cover as layered source + high-res square PNG (to 3000×3000) — no per-city artwork. - A short style sheet: icon grid/stroke rules, color palette, brand motif, and sizing guidance so we can extend the system later. Skills - Strong icon / app-mark portfolio (show launcher icons and icon systems that work at small sizes). - Mobile UI + onboarding experience. - A point of view on color + brand; bonus for civic / news / editorial work. To apply, include - 2–3 relevant portfolio pieces (app icons + icon systems especially). - One line on your concept direction for an iconic HeyCity app icon. - One line on how you'd keep the category icons legible at 18px. - One line on how you balance "trustworthy" with "colorful, not dull." - Your timeline and rate. Logistics - Budget: [your range] - Timeline: [your target] Reference materials (attached) - city-collage-app-icon.png — current app icon (the "city collage"), the flagship asset to reimagine. - category-icons-contact-sheet.png — the 11 current icons at 72px and at their real 18px card size. - icons/*.svg — each current category icon as a standalone SVG. - collage-mark.png — the same collage motif wrapped in headphones, used on podcast covers. - sample-podcast-cover.jpg — a representative finished podcast cover (collage + wordmark). - Onboarding screenshots — add phone screenshots of the current intro flow before posting.
