Enterprise Distribution
MDM / APK sideload — iOS & Android
Apple releases iOS each September. Google ships major Android versions quarterly. Each release breaks something — deprecated APIs, changed permission models, modified system UI. Without active monitoring, you find out from 1-star reviews, not alerts.
How we prevent it
We monitor Apple and Google beta tracks 3–4 months before public release. Your app is tested on every beta build, compatibility fixes are submitted, and you ship on launch day — not 3 weeks after.
iOS and Android release new versions every year — and break things. We update your app before Apple's deadline and before Android users start leaving 1-star reviews.
Firebase Crashlytics or Sentry monitoring with weekly crash reports. Every crash gets triaged by severity and fixed in priority order — critical issues same day.
App startup time, scroll smoothness, image loading, and battery usage audited and improved. Users notice when apps are slow — and they uninstall.
Dependency audits, CVE monitoring, certificate renewals, and API security updates. We patch before vulnerabilities become incidents.
A/B testing screenshots, updating metadata, responding to reviews, and keyword optimization — keeping your store listing competitive.
Retainer-based feature work with no ramp-up time. We're already inside your codebase — we scope and deliver features faster than any new agency would.
Eight standard deliverables on every engagement. Not upsells — these are the baseline because cutting any one creates the exact incidents we exist to prevent.
OS Compatibility Updates
Beta-tested against iOS and Android releases 3–4 months before public launch — shipped before your users hit it
Crash Monitoring
Security Patching
Performance Audits
Monthly Health Report
Feature Development
Retainer-based work inside your codebase — no ramp-up time, no handoffs
Store Listing Management
Metadata updates, screenshot A/B tests, review responses, and policy compliance — both stores
Dedicated Engineer
One engineer who knows your codebase — not a rotating support queue or a ticket system
All 8 deliverables — standard on every maintenance engagement, no exceptions.
From codebase handoff to monthly maintenance cadence — fully operational in week two.
We review your existing codebase, crash history, dependency versions, OS coverage, and store standing. Deliverable: health report with priority fixes and a maintenance plan.
Firebase Crashlytics or Sentry configured, alerting thresholds set, performance baselines established. Play Console and App Store Connect analytics wired into our dashboard.
OS beta testing, dependency updates, crash triage, security patches, and feature work — delivered on a monthly cadence with a written report each cycle.
Full app review every 3 months — performance, store standing, user feedback analysis, and roadmap recommendations. You always know the health of your app.

If yours is not here, reach out. We respond within 24 hours with a real answer from an engineer — not a sales pitch.

We monitor Apple and Google developer releases and begin compatibility testing as soon as betas are available — typically 3–4 months before public release. Your app is updated, tested on the new OS, and submitted before it goes live. No scrambling, no emergency fixes.
This is one of the most common reasons companies come to us. We perform a codebase audit, document what we find, and take over maintenance from any existing codebase — iOS, Android, React Native, or Flutter. We'll be honest if the codebase needs a partial or full rewrite.
Yes. Ongoing feature development is part of every engagement. Because we're already inside your codebase, there's no ramp-up time — we scope and deliver features faster than any new agency would.
Firebase Crashlytics or Sentry for crash monitoring, Firebase Performance or DataDog for performance metrics, and App Store Connect / Play Console analytics for user trends. We set up dashboards you can access at any time.
Month-to-month. Cancel with 30 days notice. We don't lock clients in — we retain them by making the app better every month. iOS and Android are both covered on every engagement.
Maintenance retainers typically run $1,500–$6,000 per month depending on app complexity, store presence, and how much ongoing feature work you need. That covers OS compatibility updates, crash monitoring, security patches, store compliance, and a dedicated engineer who already knows your codebase. It is a fraction of what a single emergency rebuild or store removal costs.
Critical crashes carry a sub-24-hour fix SLA. Firebase Crashlytics or Sentry alerting pages our on-call engineer within minutes of a spike, we triage by severity, and a fix or rollback ships the same day for anything affecting auth, checkout, or core flows. You are never waiting on a ticket queue.
Yes. We audit startup time, scroll smoothness, memory, and battery usage, then optimize the worst offenders — typically lifting crash-free rates above 99% and cutting cold-start times measurably. We benchmark before and after every cycle so you can see the gains in real Play Console and App Store Connect metrics.
“Ethersofts took over a project two agencies fumbled. They untangled the mess, rebuilt critical parts, and shipped in 6 weeks. The codebase is clean and our users actually like it now.”
