When a call slips through the cracks I don’t want prospects left hanging. I need a small, reliable app that watches for any missed or declined call on both Android and iOS, then instantly fires off a friendly SMS that includes the booking link already live on my website. The goal is simple: give callers a friction-free way to reserve a follow-up slot the moment we miss them. Alongside that SMS trigger I want speech-to-text built in. When the caller leaves a voicemail, the audio should be transcribed in English so I can quickly scan what they needed, tweak the wording if necessary, and forward the summary together with the same calendar link. That extra personal touch shows we listened before we even call back. just inserting the existing URL into each outgoing message. Key things I’ll look for: • Accurate detection of missed or rejected calls on both platforms • Instant SMS with our booking link (no noticeable delay) • Cloud or on-device transcription that returns clean English text from voicemail audio • A simple interface where I can review, edit and resend the transcript + link in one tap If you’ve previously worked with call states, SMS gateways (e.g., Twilio, Firebase, or native APIs) and speech-to-text engines such as Google Speech or Apple’s built-in transcription, you’ll hit the ground running. Clean code, clear setup instructions and a quick video demo of the workflow will be the final deliverables. Project will be under NDA.

Hello There!!! ⚜⭐⭐⭐⭐⚜(( Missed call auto response with SMS booking link and voicemail transcription ))⚜⭐⭐⭐⭐⚜ Your idea is very practical and revenue focused. Every missed or declined call becomes an opportunity to respond instantly with context, not a generic follow up. The combination of real time SMS and voicemail transcription shows callers they were heard and gives them an easy next step without waiting. You are looking for a lightweight Android and iOS app that reliably detects missed call states, triggers an immediate SMS with your existing booking link, and converts voicemail audio into clean English text that can be reviewed and forwarded in seconds. Reliability and speed matter more than extra features here. I have worked with call state listeners, SMS gateways like Twilio and native APIs, and speech to text pipelines where timing and accuracy directly affect user trust. My focus is clean workflows, predictable behavior, and simple interfaces that do not get in the way. Three key features I would deliver: 1. Accurate missed and declined call detection on Android and iOS 2. Instant SMS delivery with your booking URL inserted automatically 3. Voicemail transcription with quick edit and resend flow If this aligns with how you want missed calls handled going forward, I would be glad to discuss scope, timelines, and a realistic fixed price. Warm Regards, Farhin B.

Hello, Service Gap Missed or declined calls are costing you opportunities because callers don’t get an immediate, easy way to book a follow-up. On top of that, voicemails take time to listen to, which delays response and reduces personalization. Implementation Plan I will build a lightweight cross-platform mobile app that reliably detects missed or rejected calls on both Android and iOS using native call-state listeners. The moment a call is missed, the app will trigger an automatic SMS through a trusted gateway (such as Twilio or native APIs) containing your existing booking link—no delay, no manual action. For voicemails, I’ll integrate a speech-to-text engine (Google Speech or Apple’s native transcription) to convert audio into clean English text. You’ll have a simple screen to review, edit, and resend the transcript along with the booking link in a single tap. End Result You’ll never leave a prospect hanging again. Every missed caller instantly receives a friendly SMS with your booking link, voicemails are readable at a glance, and follow-ups feel personal and fast. The app will be cleanly coded, easy to set up, NDA-safe, and delivered with clear documentation and a short workflow demo. 15+ years of practice help me balance speed, clarity, and reliability.

Hi there, To ensure missed calls never turn into missed bookings, the most critical part is detecting call events reliably and triggering SMS follow-ups instantly—while staying within iOS and Android platform rules. I’ll approach this with an Android-first core app that monitors missed or declined calls, immediately sends an SMS with your existing booking link, and transcribes voicemail audio using a proven speech-to-text engine. Transcripts can be reviewed, edited, and resent in one tap for that personal touch. For iOS, I’ll implement a compliant companion approach using supported APIs and cloud-based call/SMS workflows rather than unsupported background monitoring. I’ve built mobile automation tools involving call states, SMS gateways, and transcription where reliability and OS compliance were non-negotiable. That experience ensures this solution works in the real world—not just in theory. My process starts with platform feasibility mapping, then core detection and SMS logic, followed by transcription, UI polish, and demo delivery. I’m ready to get started.
