At RocketShip HQ, we have spent years building internal tools to manage ad spend, test creatives, and optimize subscription app economics for our clients. We decided to make the most useful ones available to everyone, completely free and with no signup required.
Whether you are a solo app developer planning your first campaign or a growth team managing millions in ad spend, these tools help you make better decisions with your own data. Every calculator uses your inputs only, with no subjective benchmarks or dated “industry averages” that may not apply to your specific situation.
Ad Preview Tools
See exactly how your ads will look before you publish them. Upload your creative, enter your ad copy, and get pixel-perfect mockups of every major ad platform. Catch cropping issues, text overflow, and CTA placement problems before spending a single dollar. Preview tools are available for Meta (Facebook + Instagram), TikTok, Snapchat, YouTube, AppLovin, and Pinterest.
Marketing Calculators
Our calculators help you plan campaigns, allocate budgets, and forecast results. The Ad Cost Calculator covers lead generation, e-commerce, and app install models. The Creative Testing Calculator tells you how many creatives to produce and what your testing budget should be. The Subscription App Revenue Calculator models weekly, monthly, and annual plan economics with platform commission modeling and payback period calculations.
Frequently Asked Questions
Are these tools really free?
Yes, 100% free with no signup, no account, and no usage limits. We built them to be genuinely useful, not as gated lead magnets.
Do I need to create an account?
No. Every tool works instantly in your browser. No registration, no email required.
Is my data stored anywhere?
No. All calculations happen in your browser. Ad preview images are processed locally using your browser’s FileReader API and are never uploaded to our servers. Your data stays on your device.
Who built these tools?
RocketShip HQ, a mobile growth agency that has managed over $100M in ad spend for apps like MobilityWare, JobGet, and Players’ Lounge. These tools are built on the same frameworks we use for our clients.
Can I use the ad preview mockups in presentations?
Absolutely. The preview tools are designed for exactly this. Use them to create mockups for client presentations, internal reviews, or stakeholder approvals.
What are the upcoming AI-powered tools?
The Creative Brief Generator will use our proprietary 3C Principle and 4-Layer Hook System to generate structured creative briefs from your app details. The Ad Hook Scorer will analyze your ad copy openings and score them on Context, Clarity, and Curiosity. Both tools will be available soon.
