Abstract
Notepad shows an ad on nearly every interaction — opening, editing, and exiting a note — and reviewers who specifically paid to remove ads report still seeing them; the complaint is real and severe, but the ceiling is capped by the fact that Google Keep and Samsung Notes already offer the same basics free and ad-free.
Background
For its users, Notepad, Notebook, Notes app is a simple text-note and checklist app with reminders, used for grocery lists, quick notes, and lyrics/scripts.
What it does
Plain-text and checklist notes with reminders, color coding, and cloud sync.
What changed
Interstitial ads now appear on opening the app, opening a note, editing, and exiting — even for users who paid specifically to remove ads.
Why it is soft
The ad-fatigue complaint is loud and specific, but several reviewers themselves point out that free, ad-free built-in alternatives already exist, which limits how much a clone can realistically charge.
Strengths
The core note-taking loop itself isn't in question — reviewers who aren't complaining about ads describe it as simple and useful for day-to-day lists and reminders.
Market gap
The recurring complaints, grouped by frequency:
Ads on nearly every interaction
Opening the app, opening a note, editing, and exiting each trigger an ad — the dominant complaint by a wide margin.
Ads persist for paying users
Several reviewers who paid specifically for an ad-free tier report still seeing ads — a trust-breaking bug, not just an annoyance.
Occasional data loss
A smaller but severe cluster: notes disappearing after a crash, background switch, or update.
Free built-in alternatives exist
Multiple reviewers point out Google Keep and Samsung Notes already do the same thing, ad-free, for free.
I'm actually PAYING a membership for this very basic notes app, and now you're telling me that you've added ads into the app???
People who subscribe for no ads still get ads. It has a $12 per month subscription to give you ad free "premium" but you will still get ads.
- Ship truly ad-free at a low one-time price, not a subscription — the bar to clear is simply "fewer ads than this," which is low.
- Honor paid ad-removal completely. If entitlement checks are wrong, that's a trivial fix worth getting right given how visible the complaint is.
- Reliable local-first storage with autosave and undo, since disappearing notes is the complaint that permanently loses a user, not just annoys one.
Build complexity
Estimated for one developer, part-time, no funding, no paid acquisition. This is a deliberately small build.
| Workstream | Weeks |
|---|---|
| Note CRUD + local-first autosave | 1 |
| Reminders/checklist | 0.5 |
| Optional cloud sync | 1 |
| Ad-free paywall (one-time unlock) | 0.5 |
| Total | 3 |
Expected revenue
Priced at $1.99 one-time, not a subscription — reviewers here explicitly reject paying recurring for something this simple.
| Month 12, monthly | ||
|---|---|---|
| Installs | 6,000 | |
| Activated | 2,400 | 40% |
| Still on at 30d | 900 | 15% |
| Paid | 240 | 4% |
| Revenue | $480 |
Biggest challenges
The real fight is distribution, not the build — Google Keep and Samsung Notes are free, ad-free, and pre-installed, so a new entrant is competing against the OS default, not just this one bad app.
AI angle
No strong genuine angle for this specific gap — AI-assisted summarization or checklist extraction is a nice-to-have, but it doesn't address the actual complaint (ads and broken trust), so it shouldn't be the reason to build this.
Conclusion
Build it. A cheap, low-risk build with a loud, specific complaint — but be honest that the revenue ceiling is thin against free built-in alternatives.
