Hi, I'm Harsh Thoriya. I've reviewed your requirements and understand you need a cross-platform iOS/Android app for image-to-PDF conversion with live file-size comparison, coin-based system, in-app purchases (Apple/Google Pay), referral link rewards, and a secure backend. I'll design the full UI/UX from onboarding to purchase flow, then build the production app using Flutter with Laravel/Node.js backend, payment gateway integration, and referral system. I specialize in Flutter + Laravel app development with payment integrations. Let's connect and discuss!

Dear client, I can provide you flutter based image to pdf converter app, I have more than 9 years of exp in apps and web development.

@iimtpradeepdash

Hi! The way you want a live "before vs after" file size comparison for the image-to-PDF step is the tricky part — especially offline and across both iPhone and Android. Many apps skip this, but it's what makes the conversion feel real for users. I've shipped mobile apps with camera, PDF, and payment flows before. For yours, I'd suggest Flutter. One code base handles both platforms, handles Apple and Google pay well, and the UI looks native. Performance with big batches is solid — I've done gallery-based PDF tools with Flutter and know how to keep memory usage tight. A smart question — for referrals, do you need deep link tracking (so a user clicks the link, installs, and the app knows which inviter to credit), or is a simple code entry enough? Happy to sketch the full flow from onboarding to purchase as a free Figma outline. For similar work and demos, see work.techindika.com. — Pradeep

Hi — read the brief. For this I'd lean React Native: one codebase, fast iteration on the coin/IAP flows, and image-batch performance holds up if we offload PDF assembly to native modules (react-native-pdf-lib). Quick plan: Figma first (onboarding → picker → live size comparison → coin packs → referral) → offline conversion → StoreKit 2 + Google Play Billing for coin packs (RevenueCat optional for unified receipt validation) → Node/Express backend for balances and referral attribution (device + install fingerprint so the reward fires once) → small admin panel for coin price / referral % / size thresholds. We've shipped cross-platform apps with IAP and referral flows before. Realistic timeline: ~5 days design, ~3 weeks dev, plus a buffer for store reviews. Ping me to lock scope. — Rohan, APIE Tech

@serviceaxisgroup

Hi, I can help with a clean iOS/Android mobile app that converts multiple photos into one PDF and shows an instant before vs after file-size comparison. I’ll start by designing the full onboarding, UI/UX, and the coin purchase + conversion flows, then validate with a clickable Figma prototype. To reduce risk, I’ll build a small offline conversion + size-preview proof early and then integrate real payments and secure backend tracking only after the UX is approved. Do you want the app built with React Native or Flutter for smooth large-batch performance? Also, should size-comparison thresholds be configurable per platform or globally? If you share any target screen references, I can send a timeline and next steps right away.

Hi, I can design and develop this complete image-to-PDF coin-based app for both iOS and Android using Flutter + Firebase backend. Flutter is the best fit here because it gives a single high-performance codebase, smooth PDF/image processing, faster delivery, and easier long-term maintenance across both platforms. What I’ll deliver: Full UI/UX in Figma with clickable prototype Offline image-to-PDF conversion with instant size comparison Coin system with secure balance tracking Referral reward system (1 reward per unique install/device) Apple & Google in-app purchases integration Production-ready Android + iOS builds Clean documented source code + admin settings guide Tech Stack: Flutter (cross-platform) Firebase Auth + Firestore + Dynamic Links RevenueCat / native IAP integration Local PDF/image compression engine for offline processing Estimated timeline: UI/UX Design: 4–5 days App Development: 12–15 days Testing & Store-ready polish: 3–4 days Total: ~3 weeks Bid: ₹1,500 INR (initial project milestone discussion; final scope pricing can be adjusted based on backend/admin complexity) I can also suggest optimization methods to keep PDF generation fast even with large image batches while maintaining visible compression savings.

@ZainabWeb6

I recommend using Flutter because it supports both iOS and Android with one codebase, gives smooth performance, and reduces development time. Tech Stack: UI/UX: Figma App: Flutter Backend: Firebase Payments: Apple & Google in-app purchases Features: Offline image-to-PDF conversion Live before/after file-size comparison Coin system with secure purchases Referral rewards (one-time per user/device) Admin panel for coin prices & referral settings Timeline: Design: 5–7 days Development: 2–3 weeks Testing & Store Submission: 5–7 days Total: Around 4–5 weeks for a production-ready app.

@macymind

Hi I went through the scope and the app idea is clear. The main thing here will be keeping the PDF conversion fast and smooth while making the coin and referral flow feel simple for users instead of overly complicated. Since the UI still needs to be designed, I’d first focus on the onboarding, conversion flow, and purchase experience before moving into development. The main parts I’d handle are: =>UI/UX design + prototype =>Offline image-to-PDF conversion =>Live size comparison =>Coin + referral system =>In-app purchases =>Backend/admin setup =>App Store & Play Store deployment I’ve worked on apps involving payments, referrals, backend integrations, and production mobile apps before. For this type of app, I’d personally recommend Flutter because it keeps both iOS and Android easier to manage from one codebase while still performing well for image processing. I also have experience with Native Android/iOS development when platform-level optimization is needed. One thing I wanted to ask do you see the app staying mostly device-based, or would you eventually want cloud sync/account backup added later as well? Regards, Manish P.
