AppStills.Feature comparison
| Feature | AppStills | Previewed |
|---|---|---|
| 3D device posing | Yes — real-time react-three-fiber editor, full 6-axis per-object transforms, perspective or orthographic camera, 4 render styles. Available on the free tier. | Yes — a core strength. 3D snapshots from any angle plus 3D animations across iPhone, iPad, MacBook, iMac and Android. 3D export is paid-only (excluded from the free Lite plan). |
| Store-listing import (name/screenshots/colours from an App Store or Google Play URL) | Yes — search + import pulls listing metadata and screenshots; Claude vision classifies each image and suggests brand colours + a layout. Both tiers (sign-in required). | No — not mentioned anywhere on their own site. |
| AI captions / content suggestions | Yes — generates headline + subtitle per screen from the app's own store text at import (Claude Haiku). Both tiers. (In-editor AI content suggestions and AI background generation are not shipped.) | No — no AI-generated captions or text suggestions described on their site. |
| Localization / translation (multi-language caption sets) | Yes (Pro) — exactly 50 App Store Connect languages, AI batch translation of the whole caption set, plus per-language screenshot overrides and position nudges. | No — their 'Localization' label means saving/grouping templates, not language translation. No per-language captions or overrides. |
| App-preview / promo video (.mp4) export | Yes (Pro) — Apple-approved 15–30s H.264 (yuv420p, 30fps CFR) + silent AAC, rendered fully in-browser via ffmpeg.wasm. Phone and iPad only. | Yes — MP4 app-promo / preview video, 30fps on Plus and 60fps on Pro. Paid-only. Does not state Apple's 15–30s app-preview spec. |
| All-sizes one-ZIP export (every required size in one download) | Yes (Pro) — every store size for every chosen language streamed into one ZIP, per-size and per-language folders, pixel-exact and alpha-flattened. Free tier = one size / one language per run. | No documented all-sizes batch/ZIP — exports are custom-dimension, per-format (jpeg, png, mp4). Panoramic 'mockup sets' span frames but no all-sizes ZIP is stated. |
| Free tier | Yes — 1 project, full 3D editor + all effects + store import + AI captions; export limited to a single size / single language per run. | Yes — 'Lite' free-forever: unlimited 2D exports capped at 720p under a CC Attribution license. 3D and video are excluded from the free plan. |
| Watermark-free free export | Yes — free exports are watermark-free; the 'Made with AppStills.com' mark was removed, so both tiers export clean. | No watermark stated on their own site; the free-tier constraint is a CC Attribution license (credit required) plus a 720p, 2D-only cap. Watermark status left unverified. |
| Pricing | Free $0. Pro $5.90/mo or $49.90/yr (~30% off yearly), read live from Stripe. Up to 50 projects. | Lite free. Plus $9.99 one-time (10 exports at 1080p+, 3D, 30fps video, commercial license). Pro $19/mo billed $228/yr (unlimited exports, 60fps video, priority support). |
| Platform | Web only (Next.js, no install); sign-in required, no offline mode. Exports Apple App Store + Google Play store sizes only. | Web only (no install). Broader scope: also Mac/iMac device mockups and social-media mockups (Instagram, Facebook, Twitter, LinkedIn), plus team/collaboration features. |

Where each tool is stronger
Where AppStills is stronger
- Store-listing import: pull an app's name, screenshots, brand colours and a suggested layout straight from an App Store or Google Play URL (Claude vision) — Previewed has no equivalent.
- AI caption generation from the app's own store text at import; Previewed offers no AI captions.
- Real localization: 50 App Store Connect languages with AI batch translation plus per-language screenshot overrides and position nudges (Previewed's 'Localization' is only template grouping).
- One-click batch export of every store size for every language into a single streamed ZIP, pixel-exact and alpha-flattened, with per-size/per-language folders.
- Store-specific pixel-exact presets: iPhone 6.9"/6.5"/5.5", iPad 13", Apple Watch, Google Play phone/tablet, feature graphic and Wear OS — Previewed states no store-exact size presets or Apple Watch/Wear OS support.
- The full 3D editor (all effects, store import, AI captions) is on the free tier; Previewed keeps 3D and video behind paid plans.
- App Preview .mp4 is encoded to Apple's spec (15–30s, H.264 yuv420p, 30fps CFR) entirely in-browser.
- Lower subscription: Pro at $5.90/mo vs Previewed Pro at $19/mo, with pricing read live from Stripe so it can't drift from what's charged.
Where Previewed is stronger
- Broader device and scene coverage: MacBook and iMac mockups plus social-media mockups (Instagram, Facebook, Twitter, LinkedIn), not just app-store devices.
- 3D animations (animated mockups), which AppStills does not offer.
- Higher-frame-rate video: preview/promo MP4 up to 60fps on Pro, versus AppStills' 30fps.
- A one-time $9.99 Plus license unlocks 3D and video without any subscription — AppStills gates the equivalent behind a recurring Pro plan.
- Free plan allows unlimited 2D image exports (albeit 720p, 2D-only, with CC attribution), whereas AppStills' free export is capped to a single size/language per run.
- Large ready-made mockup / template library with cloud template storage and grouping, plus team/collaboration features.
When Previewed is the better choice
Choose Previewed if your work extends beyond App Store and Google Play screenshots — you need Mac or iMac device shots, social-media mockups, or animated 3D scenes and 60fps promo video. It's also the better pick if you want to unlock 3D and video with a single $9.99 one-time purchase instead of a subscription, or want a large ready-made mockup library and team features. Previewed is the more general-purpose mockup generator; AppStills is narrower and purpose-built for store screenshots.
Verdict
For shipping App Store and Google Play screenshot sets, AppStills does things Previewed simply doesn't: import an existing listing, write AI captions, localize into 50 languages, and export every required store size (for every language) as one pixel-exact ZIP. It also puts its full 3D editor on the free tier and costs less ($5.90/mo Pro vs $19/mo). Previewed is the broader tool — Mac/iMac and social mockups, 3D animations, 60fps video, and a one-time $9.99 unlock — and is the better choice when you need general-purpose or animated device mockups beyond the app stores, or want to avoid a subscription. Both run in the browser with no install. Pick AppStills to produce localized, store-ready screenshots fast; pick Previewed for versatile cross-platform mockups.
