IOS developer| Building with AI

I’ve run for 10+ years. I still struggle to keep long runs easy. So I built Coachi for myself. It is not another tracker. It is a voice coach that tells me when my heart rate is too high or too low. So I can stop staring at my watch and just run.

@Maddyy660263 @X Building Coachi with AI in a small loop: iPhone + watch app, Garmin support, and live run cues. The hard part is making coaching feel calm during the run, not like another screen full of metrics.

@abishuablessmic Coachi - AI running coach for runners who want live cues instead of another passive tracker. It guides the session, helps keep effort in the right zone, and explains the run afterward. coachi.no

@sycode_x Building Coachi: an AI running coach for everyday runners. Current focus is making the watch/phone feel less like a dashboard and more like a coach: simple live effort cues, then one practical post-run fix.

@dhruvalgolakiya @bas_fijneman Coachi - AI running coach for iPhone + watch. It helps runners choose a session, stay in the right effort zone during the run, and leave with one clear thing to improve. coachi.no

@bas_fijneman drop your app link if you want to test it for your app, will start posting this type of post for any random app daily

generated 4 different screenshot styles for PufferPages by @bas_fijneman using appgrowkit.com all of these were generated in under 5 minutes and each version uses different ASO context based on rankings, competitors, and keyword opportunities to give you option to A/B test

@vladfromweb Seeing this while working on Coachi. Screenshots are not decoration - they are the first product demo. I’m testing whether the first frame should lead with the live zone cue, not the post-run analysis.

@sureshbabudj Building Coachi, an AI running coach for everyday runners. The product is moving from tracking toward coaching: pick a workout, get live effort cues during the run, and leave with one practical thing to improve.

Indie devs, What are you building right now? Show me your app, your repo, your prototype, your chaos. I want to see the cool stuff happening outside big tech.

@roeytechai Coachi - AI running coach for iPhone + watch. Core wedge: live run cues so runners can stay in the right zone without constantly checking the watch, then one clear fix after each run. coachi.no

You know that feeling when your project should be doing better… But you can't figure out what's holding it back? Drop your app, project, or website below. I'll tell you what I see. Raw and honest.

@improvemypage @X Appreciate it. Even from a non-runner view, the thing I would want tested is whether the problem is clear in 5 seconds: less guessing during the run, clearer feedback after it.

@DailyRun49173 @X Hi there ! I’m not a runner but I’ll have a look at it! Let’s connect 😃

Hey @X algo, I’m quite new here and I’d love to connect with people interested in: - SaaS - E-commerce - AI - Automation - Software development - Web development - Web3 - Marketing If you’re into that or anything related, drop your project below 👇 and let’s connect

@itpapo4ka @roudyhermez That is useful feedback. I agree the first screenshot should probably lead with the runner benefit: stay in the right zone without checking your watch. The post-run coaching is important, but the in-run cue is the wedge.

Hey friends 👋🏻 As a small thank-you to this community, I’ll install and test your iOS app for a full day 📱 Then I’ll: ✅ Share my honest feedback in the replies ✅ Leave an App Store rating & review (5⭐️ only if I genuinely think it deserves it) ❌ I won’t leave negative reviews if your app isn’t my cup of tea ⏳ First come, first served. What I’ll review: 🔹 App’s overall purpose & value 🔹 App Store description 🔹 Screenshots & presentation 🔹 UI/UX experience 🔹 First impressions & onboarding 💡 I’ll also share suggestions for improvement if I spot any opportunities. Drop your app below 👇🏻

@jig_corp Exactly. The useful part is not another chart after the run. It is the cue while you still have time to adjust: ease off, hold steady, or stop over-correcting.

@DailyRun49173 The effort zone feature is a total game changer for building actual stamina

Coachi update is live. Voice-guided AI coaching now supports runners using Apple Watch + Garmin. Less staring at zones. More clear cues while you run. Download: apps.apple.com/us/app/coachi-…

@YotamBlu Garmin is great at collecting the signal. The missing piece for a lot of runners is turning that signal into one useful cue at the right moment. That is the direction we just pushed Coachi toward with Garmin support.

garmin just launched the forerunner 70, 170, and 170 music, shipping tomorrow, may 15. AMOLED screens. adaptive coaching. training readiness on entry-level hardware. the most capable budget garmin running watches ever made. and they're still entirely athlete-facing. the coach still can't see the data unless the athlete shares it. more capable watches. same gap. goosenet.space 🏃

@harjjotsinghh @robinjeanneyli That line is exactly why I am building Coachi. Most runners do not need another dashboard after the run. They need the small cue during the run, before the easy session quietly turns hard.

That feedback line IS your positioning - 'I thought I needed more data, I needed a coach.' Every running app (Strava, Garmin, Runna) drowns people in metrics; almost none tell you what to DO. Oscar's wedge: 'the running app that coaches you, not just charts you' - put that quote verbatim atop your landing page, it converts better than anything you'd write. Zero churn at 20 is real signal, so nail what made those 20 stick and engineer every new user into that first-week path before scaling. Distribution: r/running, r/AdvancedRunning, Strava clubs. If a coach-not-dashboard landing page is the slow part, Moonshift builds and deploys overnight with code in your repo: moonshift.io, first run completely free. What did the sticky 20 do in week one?

Oscar update 🏃 20 runners. Zero churn. Best feedback so far: "I didn't know I needed a coach, I thought I just needed more data." Ship first. Learn from real people. Then write the copy. #buildinpublic

@DavidDack This is the exact Garmin trap: the watch tells you the zone, but not always what to do next. The useful layer is a simple cue during the run: ease off, hold, or stop over-correcting.

Is Zone 2 making runners smarter… or just giving us a scientific excuse to jog slowly while arguing with a wrist computer? Because half the time “easy running” looks like patience. And the other half looks like a runner negotiating with Garmin like it owes them money.

New Coachi update is live. Voice-guided AI coaching for runners: real-time cues, smarter zones, and clear post-run feedback. Train with less guessing: apps.apple.com/us/app/coachi-…

@itpapo4ka @roudyhermez Appreciate that feedback. That makes a lot of sense. I’ve been thinking the same: the clearest value is helping runners stay in the right heart-rate zone without constantly checking their watch.
