The short answer
When a bug appears after your app launches, your job is to capture it clearly, decide how serious it is, and get the right information to whoever fixes it. You do not need to understand the code. You need a simple triage process, a way to record what happened, and a clear agreement with your developer about what counts as urgent.
Why bugs after launch are normal, not a crisis
Every app ships with some bugs. No amount of pre-launch testing catches everything, because real users do things testers never anticipate: they use old browser versions, they paste unusual characters into fields, they click buttons in an order nobody designed for. A bug surfacing post-launch does not mean your developer did poor work. It means real-world usage has started.
The problem for non-technical founders is not the bugs themselves. It is not knowing how to respond to them calmly and systematically. Without a process, you either overreact (treating every glitch as a catastrophe) or underreact (ignoring something that is quietly blocking users from paying you).
This article gives you that process.
Step 1: Capture the bug before you do anything else
The most useful thing you can give a developer is a reproducible report. That means writing down:
- What you (or the user) were trying to do
- The exact steps taken, in order
- What happened instead of what was expected
- The device, operating system, and browser (if applicable)
- A screenshot or screen recording if possible
A vague message like "the checkout page is broken" wastes everyone's time. A report that says "On iPhone 14, iOS 17.4, Safari: after adding an item to the cart and tapping Checkout, the page goes blank and nothing loads" can be acted on immediately.
Ask your first users to send reports in this format. A short template in your onboarding email saves hours of back-and-forth later. See How to Onboard Your First App Users for how to set that expectation early.
Step 2: Triage by severity before contacting your developer
Not every bug needs immediate attention. Treating them all the same exhausts your developer relationship and your own energy. Use a simple four-level system:
| Severity | Definition | Example | Target response |
|---|---|---|---|
| Critical | App is unusable or data is at risk | Login fails for all users, payment errors | Fix within hours |
| High | A key feature is broken for some users | Password reset emails not sending | Fix within 1–2 days |
| Medium | Feature works but behaves unexpectedly | Wrong date shown in confirmation email | Fix in next release |
| Low | Minor visual or UX issue | Button alignment off on one screen size | Backlog |
Before you contact your developer, assign a severity level. This tells them how to prioritize without leaving it ambiguous, and it prevents you from accidentally treating a cosmetic issue as an emergency.
Step 3: Know what your post-launch support agreement covers
Many non-technical founders skip this conversation at handover and regret it. Before your app goes live, confirm in writing:
What is covered under warranty or support. Most developers include a short bug-fix period (commonly 30 to 90 days) for defects in the original build. Understand what qualifies as a defect versus a new feature request.
What is a new feature request. If a user asks for something that was never in the original spec, that is not a bug. Calling it one creates confusion and erodes trust with your developer. If you are unsure, describe the original requirement and ask explicitly.
Response time expectations. Agree on how quickly critical bugs will be addressed. Do this before launch, not during an incident.
How to submit issues. Some developers use project management tools like Linear, Jira, or Notion. Others prefer email or a shared document. Use whatever channel they specified and keep all bug reports in one place.
Step 4: Distinguish bugs from user confusion
A significant portion of post-launch "bugs" turn out to be users who do not understand how to use a feature. This is still your problem to solve, but the solution is different: clearer onboarding or UI copy, not a code fix.
Before escalating to your developer, try to reproduce the issue yourself. If you can reproduce it, it is likely a real bug. If you cannot, ask the user to walk you through exactly what they did. Often the issue resolves or becomes clearer.
This distinction also matters financially. Developers charge for new work. If you log ten bug tickets that turn out to be onboarding gaps, you have spent time and possibly money on the wrong problem. A good system for collecting user feedback after launch helps you separate product confusion from genuine defects.
Step 5: Communicate with affected users
When a real bug affects users, say something. You do not need to explain the technical cause. A short, honest message goes a long way:
"We found an issue with [feature] that affects some users. We're working on a fix and expect it resolved by [date]. Thank you for your patience."
Do not promise a specific fix time unless you have confirmed it with your developer. Under-promising and over-delivering keeps trust intact. Going silent while users are blocked loses it fast.
Step 6: Keep a bug log
Create a simple running document, whether a spreadsheet or a Notion table, with these columns: date reported, reported by, description, severity, status, and date resolved. Update it every time a bug is logged or closed.
This log does three things over time. First, it shows you whether the same areas of the app keep generating problems, which points to deeper issues worth addressing. Second, it gives your developer clear context when they return to old issues. Third, it becomes evidence if you ever need to dispute whether something was in scope.
You do not need software designed for bug tracking. A shared Google Sheet works fine at early-stage scale.
What to do when you disagree with your developer's priority call
Developers sometimes deprioritize bugs that feel important to you. Before pushing back, ask one question: is this bug blocking a user from completing a core task (signing up, paying, accessing what they paid for)? If yes, escalate clearly. If no, listen to the developer's reasoning. They may know the fix will take an hour or might break something else.
Good communication here is specific. "This bug is preventing users from completing checkout, which is directly costing us revenue" is more actionable than "this really needs to be fixed soon."
Planning for bugs as part of your launch week
The best time to set up your bug-handling process is before any bugs appear. What to Do the Week Your App Goes Live covers the broader launch checklist, and bug triage is one piece of that preparation. Setting up your log, confirming your support agreement, and briefing your first users on how to report issues takes less than two hours and prevents most of the chaos that follows an unplanned incident.
FAQ
How do I know if something is a bug or a missing feature?
A bug means the app is not doing what it was specified to do. A missing feature means something new was never in the original requirements. Check your original brief or specification document. If the behavior was described and is not working, it is a bug. If it was never described, it is a feature request.
My developer says the bug is not their responsibility. What do I do?
Ask them to show you where in the original specification the behavior in question was addressed. If it is genuinely outside scope, you will likely need to pay for the fix as new work. If you believe it falls within the original spec, refer back to your written agreement and discuss calmly with specific references rather than general frustration.
How long should I expect bug fixes to take?
Critical fixes often take hours to a day once a developer is working on them. Medium bugs in a release cycle might take a week. The variation depends on how complex the underlying cause is. Ask your developer for an estimate after they have had time to investigate, not before.
Should I roll back my app if a critical bug appears?
Only if the bug poses a data loss or security risk, and only if your developer confirms a rollback is safe and faster than a patch. Rollbacks have their own risks. For most critical bugs, a targeted fix deployed quickly is the better path.
What if I do not have an ongoing support agreement with my developer?
Contact them anyway and ask for a quote to fix the specific issue. Most developers will fix post-launch bugs in apps they built, even outside a formal support arrangement, usually at their standard rate. If that relationship has ended, a new developer can review the codebase and address the issue, though it will take longer without familiarity with the original build.
