Abstract
ibis Paint's paid version ($15.99) is meant to be the upgrade from its free, ad-supported edition — but reviewers repeatedly discover that most of what they actually want (vector tools, custom canvas sizes, folders, cloud storage beyond a handful of images, premium filters) is still locked behind a separate, ongoing Premium Membership subscription on top of the purchase. That's a specific, well-documented, recurring "paid once, still paywalled" complaint across dozens of reviews — a real opening for a drawing app that's honest about what a single price actually buys.
Background
ibis Paint is a long-running, hugely popular (500M+ downloads across the series) mobile drawing/animation app; the paid version ($15.99) is pitched as the ad-free, fully-unlocked upgrade over the free ibisPaint X.
What it does
A drawing/painting/animation app with layers, blending modes, brushes, and manga tools.
What changed
Nothing broke — the monetization structure itself is the complaint: paying $15.99 removes ads and unlocks brushes, but leaves vector tools, larger canvases, folders, and cloud storage behind a separate subscription.
Why it is soft
Dozens of reviewers describe feeling misled by the exact same pattern, in the exact same words: "there's only a few differences from the free version."
Strengths
The drawing engine itself is genuinely well-regarded — smooth 60fps drawing, a huge brush library, and enough layer/blending depth that professionals use it. The complaint is entirely about what's gated, not about drawing quality.
Proven drawing engine
Reviewers with years of use call it the best mobile art app they've tried, brushes and all.
Massive addressable audience
500M+ downloads across the ibisPaint family shows enormous demand for mobile drawing tools at this price range.
Market gap
The recurring complaints, grouped into clusters, most-common first.
Paid once, still paywalled
The dominant complaint: the $15.99 purchase unlocks brushes and removes ads, but vector tools, folders, custom canvas sizes, and real cloud storage need a further subscription.
Confusing tier structure
Free (ibisPaint X) vs. paid vs. ad-removal vs. Premium Membership is four overlapping tiers reviewers say they can't tell apart before buying.
Reliability
A smaller cluster reports crashes, freezes, and lost brush catalogues, especially in the animation workspace.
Bought it thinking; Surely the complete version would come with all the features, right? No, no it does not. God forbid you pay for something and it has the features unlocked. With this version you only get the brushes, things like tools are still locked.
There's only a few differences from the Ibispaint X. Well yea the brushes are free, there's no ads, and the canvas is wider but that's it??? this is not worth the money at all i expected more.
Don't get me wrong. Its a good drawing app but its not worth buying this premium version. Even when you buy this version a lot is still locked behind the monthly paywall. The only difference is no more ads to get brushes.
- Sell one tier, at one price. A $12.99 one-time purchase that unlocks everything — layers, folders, cloud sync, larger canvases — directly answers the loudest complaint.
- Lead with a smaller but honest brush/filter set. Reviewers don't need 105,000 brushes; they need to trust that what they bought is actually theirs.
- Ship real (not token) cloud storage with the purchase. 10-image cloud caps behind a subscription is a specific, named complaint — even a generous fixed allotment beats that.
Build complexity
Estimated for one developer, part-time, no funding. A focused drawing app — solid brush engine, layers, and export — is achievable without ibis Paint's full animation/vector/manga feature set.
| Workstream | Weeks |
|---|---|
| Canvas + brush engine (30-40 brushes) | 5 |
| Layers + blending modes | 3 |
| Export, cloud backup, gallery/folders | 2.5 |
| Store listing + billing | 1.5 |
| Total | 12.0 |
Expected revenue
Assumes a $12.99 one-time price with everything unlocked, undercutting the incumbent's effective total (purchase + subscription) while explicitly marketing "no second paywall."
| Month 12, monthly | ||
|---|---|---|
| Installs | 70,000 | |
| Activated | 28,000 | 40% |
| Paid | 385 | 1.4% |
| Revenue | $5,000 |
Biggest challenges
A drawing app lives or dies on brush feel and animation smoothness — that's a lot of low-level rendering and input-latency tuning for one developer, and ibis Paint's own users are picky about exactly this.
Brush-engine polish
Stroke smoothing, pressure sensitivity, and 60fps rendering across fragmented Android hardware is real, hard-to-shortcut work.
Cold-start trust in a crowded category
Procreate, Krita, and dozens of drawing apps compete here — differentiation has to be the pricing honesty, loudly marketed.
AI angle
A real but narrow angle: AI-assisted line cleanup or color-fill ("AI Disturbance"-style tools) are now available as small on-device or API-based models, letting a solo builder offer one differentiated feature without building a research-grade CV model in-house.
Conclusion
Build it. A specific, well-documented, dozens-of-reviews-deep complaint about paid-once-still-paywalled monetization, against a proven, large market for mobile drawing apps.
