Launch Checklist for Mobile App Campaigns
Every install decision begins with a pixel. Poor screenshots or generic banners waste ad spend and lower store conversion rates. By systematizing asset creation, you lock in consistent branding, faster iteration, and measurable lift across the funnel.

1. Pre‑Launch Visual Asset Production

AI‑Generated Screenshot Sets with DesignLumo

AI‑Generated Screenshot Sets with DesignLumo

Open DesignLumo (https://www.designlumo.com) and feed a prompt like “iPhone 15 Pro screenshot of a fitness app showing daily stats, dark mode, brand colors #1A73E8 and #FFFFFF”. Generate a fully layered PSD with editable text, icons, and background. Export each size (6.7", 6.1", 5.4") as PNG, then run ImageOptim to stay under 150 KB. Upload to App Store Connect and schedule an A/B test of two headline variations. Expect a 10‑15% lift in conversion if you hit a 2‑second load time on each image.

Dynamic Feature Graphic via Canva Pro

Dynamic Feature Graphic via Canva Pro

Log into Canva Pro, activate your brand kit, and select a custom 1024 × 500 px canvas. Import the app logo, apply the primary brand color, and use the “Animated Text” element to highlight the core value proposition. Export as a high‑quality PNG, then compress with TinyPNG to stay under 300 KB. Upload to Google Play Console; this single graphic influences click‑through rates by up to 18% when the CTA is visible within the first 2 seconds.

Custom Promo Video using Midjourney + Adobe Premiere

Custom Promo Video using Midjourney + Adobe Premiere

Generate 5‑second atmospheric frames in Midjourney (https://www.midjourney.com) with prompts like “ultra‑realistic smartphone UI animation, neon glow, 4K”. Download the PNG sequence, import into Adobe Premiere Pro, add a kinetic typography overlay using the brand font, and sync to a royalty‑free 15‑bpm track from Artlist. Export a 30‑second MP4 (1080 × 1920) under 5 MB, then schedule on TikTok and Instagram Reels via Later. Track view‑through rate; a well‑crafted video typically boosts install cost‑per‑install (CPI) by 20‑30%.

2. Store Listing Optimization Assets

Localized App Store Screenshots

Localized App Store Screenshots

Export the master screenshot set from DesignLumo, then duplicate for each target language. Replace overlay copy with localized strings using the built‑in text layers; keep font hierarchy identical to preserve brand tone. Compress each image to <150 KB, then upload to App Store Connect per locale. Run a 7‑day A/B test on the US and JP markets; historically, localized screenshots lift conversion by 12‑18% versus English‑only assets.

High‑Impact Icon Iteration via Adobe Express

High‑Impact Icon Iteration via Adobe Express

Start with a 1024 × 1024 px vector in Adobe Express (https://www.adobe.com/express). Create five variants: flat, gradient, outline, duotone, and 3‑D bevel. Export each as PNG, then use App Store Connect’s “Icon Test” to rotate weekly. Monitor install conversion; a distinct icon usually adds 5‑9% uplift, especially in crowded categories like gaming or finance.

Compliance‑Ready Promotional Banners for Google Play

Compliance‑Ready Promotional Banners for Google Play

In DesignLumo, select the Google Play banner template (1024 × 500 px). Insert brand assets, ensure no text exceeds 30% of the image, and keep the file size under 150 KB by exporting as WebP. Verify compliance with Google’s ad policies (no deceptive claims, clear CTA). Upload via the Play Console’s “Store Listing” tab and track click‑through rate; compliant, high‑resolution banners typically achieve a 2.5% CTR versus 1.1% for generic stock images.

3. Post‑Launch Growth & Retention Creatives

Update Announcement Carousel for Social

Update Announcement Carousel for Social

Use DesignLumo to produce a 1080 × 1080 carousel of three cards: version number, top three new features, and a CTA button “Update Now”. Each card remains fully editable so you can swap copy in seconds for each release. Export as a single PDF, split into PNGs, and schedule on Buffer (https://buffer.com) for Instagram, Facebook, and LinkedIn. Posts with carousel format see a 23% higher engagement rate than single‑image updates.

Milestone Celebration Assets for Community

Milestone Celebration Assets for Community

Create a template in Canva for download‑milestone posts (e.g., 10K, 50K, 100K). Include a bold number, brand color overlay, and space for user‑generated screenshots. Duplicate the template for each milestone, insert the actual numbers, and add a short thank‑you caption. Publish on Reddit, Discord, and Twitter. Communities that celebrate milestones with custom graphics experience an 18% spike in referral traffic within 48 hours.

Retargeting Ad Creative Pipeline with AI

Retargeting Ad Creative Pipeline with AI

Integrate DesignLumo’s API (https://www.designlumo.com) with Zapier to auto‑generate three ad variants for each user segment (high‑value, churn‑risk, new). Feed segment data from Mixpanel, then let the AI produce layered ad files with dynamic copy placeholders. Push the assets directly into Facebook Ads Manager via the Zapier connector. Monitor ROAS; a well‑automated pipeline can sustain a 4:1 return on ad spend while cutting creative production time from 4 hours to under 30 minutes per batch.

Before you go

  • Batchgenerate all assets in one DesignLumo session and export a zip to avoid contextswitching.
  • Always A/B test one variable at a time copy, color, or layout to isolate performance drivers.
  • Set up a 24hour monitoring dashboard in Data Studio to catch CTR drops before they affect CPI.
