The 70% feeling is not a measured failure rate
Here, 'stuck at 70%' describes a familiar feeling: the screens look convincing, but the remaining problems keep moving. It is not a claim that AI tools finish a specific percentage of an app or that most projects fail.
AI tools can be valuable for building and changing software. A working first screen is still different from a product with reliable account access, private data, payments and recovery when something fails. The next step is focused checking, not automatically abandoning the tool.
Freeze the wish list and choose one complete journey
Write down the smallest useful result your customer needs. For an appointment app, that might be requesting a slot, seeing a confirmation and letting the business manage it. A chat feed, loyalty scheme and automated marketing may be useful later, but they do not need to block that first result.
Describe acceptance criteria in plain language: a customer can complete the journey, the business can read it back, private details stay private and failures produce a recoverable outcome. Keep a separate list for future features.
- Name the primary user and the problem they are solving.
- List the screens and saved records that journey actually needs.
- Agree what success looks like for each step.
- Defer everything that is not necessary for that result.
Test what a real user would do, not just the happy path
Start from a fresh browser session and follow the complete journey with realistic sample input. Refresh halfway through, try an invalid entry and repeat an action. Check that the result saves and can be read back. Keep real customer data out of development tests.
Use two separate test users to check access boundaries. A hidden menu is not permission enforcement: private data and team-only actions need protection where the request is handled. For an app accepting money, test success, cancellation and duplicate notifications without charging a real customer for verification.
- Sign up, confirm identity where required, sign in and recover access.
- Create, edit and read back the main record after refresh.
- Confirm one user cannot read or change another user's private data.
- Check failed requests, repeated clicks and empty states.
- Check the journey on a phone as well as a computer.
Replace endless prompts with a short issue list
For each problem, record what you did, what happened and what should have happened. Include the affected screen and a safe example. Prioritize broken core actions and privacy problems before visual polish.
Save a known working version before a major change. Fix one category of problem at a time, then repeat the whole journey to catch regressions. If changes keep breaking unrelated features, an experienced developer can review the structure and help decide whether to repair, simplify or rebuild a specific part.
A mobile MVP needs an agreed release route too
Decide whether the first version is a web app or a mobile app. A mobile build brings additional questions about supported devices, developer accounts, distribution and any permissions the app actually needs. Do not add camera, background processing or offline claims simply because an idea would benefit from them.
A team can prepare an agreed build, but cannot guarantee app-store approval or review timing. Keep store review and external-service approvals separate from the development schedule, and confirm the actual platform capabilities during scoping.
Know when to bring in a team
Bring in help when you cannot explain why a core action fails, cannot verify privacy or payment behavior, or spend more time undoing changes than improving the product. A useful review starts with your current app, issue list, accounts and desired first outcome, not a promise that every unfinished app can be rescued unchanged.
At Paramount Profits, the free Idea Lab is a way to explore what your first useful version could be. We offer separately scoped web or mobile MVPs, not an unlimited rescue service or both app types for one price. If you have already built something, explain it in your answers so we can discuss what is reusable and what needs a new scope.
The personal plan is a set of ideas, not a fixed specification. We agree the first proper version together. A working product creates a better starting point for testing demand; it does not guarantee sales or income.
