Trying to publish an iOS app using Google Health API — is CASA Tier 2 + $500/year really the only path?

Hey everyone,

I'm an indie iOS developer building a small app (WeightSync Scales) that reads body weight from the Google Health API and syncs it automatically to Strava for W/kg calculations. The app is on the App Store and targets athletes who use Fitbit/Google Health scales.

I went through the full OAuth setup, added the two restricted scopes:

-`https://www.googleapis.com/auth/googlehealth.health\_metrics\_and\_measurements.readonly\`

- `https://www.googleapis.com/auth/googlehealth.profile.readonly\`

Filled out the Data Access form, recorded a demo video, and submitted scope justifications. When I tried to submit for verification, I got a generic error: "Your app could not be submitted for verification. The attempted action failed. Please try again."

After digging around, it looks like restricted scopes require a CASA Tier 2 security assessment from an approved third-party lab (TAC Security, etc.), which costs $500–$4500/year and needs to be renewed annually.

My questions:

  1. Is this really mandatory even for a small indie app with a very narrow use case (read-only weight data, no server storage, all processing on-device)?
  2. Has anyone found a way around this — e.g., using narrower, sensitive scopes instead of restricted ones?
  3. Is the submission error a known bug, or is it actually blocking because of the missing CASA assessment?
  4. Any indie devs who went through this process willing to share their experience and timeline?

I'm currently in Testing mode with a max of 100 users, which works for now, but eventually I'd like to open it up to all users without the "unverified app" warning.

Any help appreciated 🙏

[iOS][Apple Health Companion ][Lifetime IAP: $99.99 --> $5.99][Understand your health data from apps and Apple Watch]

Hey everyone,

I have been building HealthVitals Pro for the past year, and today I want to share it with this community at a price that should be a no-brainer.

The idea is simple. If you wear an Apple Watch, you are generating thousands of data points every single day. Heart rate samples, sleep stages, HRV readings, SpO2, steps, calories, nutrition logs. Apple Health captures all of it. The problem is that surfacing any of it in a meaningful way requires jumping between multiple apps, none of which actually talk to each other.

HealthVitals Pro is the layer that sits on top of all of that data and makes it readable, actionable, and beautiful. No accounts. No cloud. Everything runs on your device.

What it does:

  • Readiness Score built from your sleep, HRV, and resting heart rate
  • Vital Intelligence alerts that detect anomalies and patterns before you notice them
  • Deep trend charts across 30, 90, and 365 days for sleep, heart, activity, nutrition, and body composition
  • Micronutrient tracking beyond just calories
  • Monthly health PDF you can actually share with your doctor
  • Full history access going back as far as your Apple Health data exists

It is designed to be lighter, faster, and more direct than anything else in the category. No bloat. No subscriptions trying to upsell you every week. Just your data, clearly presented.

Today, I am dropping the price to $5.99 for this community.

Download the app here https://apps.apple.com/app/healthvitals-pro/id6759471194 and comment "HealthLife" and I will come back to you.

If you try it, I would genuinely love your feedback. This is an indie project and every piece of input shapes the next update.

Thanks for building a community worth posting in.

[iOS][$9.99 -> $4.99 lifetime] WeightSync Scales : Your smart scale weight, synced to Strava – zero effort

Hi everyone, I'm the solo developer of WeightSync Scales, an iOS app that automatically syncs your smart scale weight to Strava -- so your W/kg is always up to date without any manual entry.

What it does:

  • Smart Scale Integration: Connect your Withings or Fitbit scale directly to the app. Every time you step on the scale, WeightSync Scales reads the measurement from your scale's cloud and pushes it to your Strava athlete profile automatically. No tapping. No typing.
  • Automatic Sync: Weights are pushed to Strava without any manual action on your part. The app works even when closed, with background sync running silently in the background.
  • Retry Queue: If a sync fails (no internet, API hiccup), the measurement is queued and retried automatically. Nothing gets lost.
  • Smart Reminders: Gentle nudges on days you haven't stepped on the scale -- useful for athletes trying to build a consistent tracking habit.
  • Units: kg, lbs, and st -- your choice, we handle the conversion.
  • Languages: English, Portuguese (Brazil), Spanish, French, Italian, German, Japanese, Chinese (Simplified), and more.

This is a solo project, and I'm still actively building it. Garmin scale support is coming soon.

Pricing:

Free to download. Premium unlocks unlimited syncs, the automatic retry queue, smart scale integration, and the Watch app.

---

If you're a cyclist, triathlete, or any athlete who tracks W/kg on Strava and owns a Withings or Fitbit scale, this app was made for you. Would love any feedback - and if you give it a try, a review on the App Store goes a long way for a solo dev.

Thanks for reading!

How many of you actually keep your weight updated on Strava?

Got curious about this after realizing my own Strava weight had been wrong for months. All my W/kg, calorie estimates, and effort comparisons were being calculated against the wrong number.

I'm asking because it seems like a common issue. Most people set their weight once when they create their account and never touch it again. But Strava uses that number in pretty much every performance calculation.

Do you have any system to keep it updated? Do it manually? Use some app?

Hi,

I’ve begun developing apps that utilize Apple Health data. I'm having trouble with the one that requires the most data, especially when running on the Simulator for App Store screenshots. How can I populate that data? Manually entering it isn’t practical, and some types of data can't be inputted at all.

thanks!

Hi.

I've just bought the Smart Band 10. I loved it. BUT...

My main health hub is Apple Health.

I authorized Mi Fit to sync everything to Apple Health, but many items, even those with data in Mi Fit, don't sync (for example, activities).

Am I doing something wrong? If not, is there any workaround?

Thanks

Hi everyone, I'm the solo developer of HydroLog, an iOS and watchOS app that helps you stay properly hydrated every day — with goals that actually adapt to your life.

What it does:

  • Dynamic Hydration Goals: Your daily goal adjusts automatically based on real-time weather conditions and your activity level using WeatherKit. Hot day? Hard workout? HydroLog recalculates so you're never under or over your target.
  • 60+ Drink Types: Log water, coffee, juice, sports drinks, and more across 14 categories. The app tracks effective hydration — not just raw volume — so a cup of coffee counts differently than a glass of water.
  • Apple Watch Support: Full companion app with a three-tab layout for checking your ring, viewing your 7-day history, and logging intake directly from your wrist. Works offline and syncs automatically. Complications included.
  • HealthKit Integration: Your hydration data stays connected to the Apple Health ecosystem.
  • Smart Notifications: A retention and reminder system that keeps you on track throughout the day without being annoying.
  • Progress Ring & Weekly Chart: Visual feedback at a glance on both iPhone and Apple Watch.
  • Languages: English and Portuguese (Brazil)
  • Still building this solo — more drink types, deeper insights, and new features are on the way.

App Store: https://apps.apple.com/app/hydrolog/id6757146528

I'd love feedback from anyone who gives it a try — especially if you have ideas for features you'd want to see. Leaving a review on the App Store also helps a lot.

Thanks for reading, and stay hydrated!
