I hate when apps make you guess what you're paying for. "Unlock premium features!" Okay, but which features? And do I actually need them?
So here's the straightforward breakdown of what Convert Pro includes, who it's for, and — honestly — who shouldn't bother upgrading.
What's Free (18 Mini Apps)
The free version of Convert isn't some crippled demo. It's 18 fully-featured mini apps:
Money:
- Currency converter (150+ live rates)
- Tip calculator
- Discount calculator
- Split bill
Time:
- Time zone converter
- World clock
- Date calculator
- Countdown timer
- Age calculator
Cooking:
- Ingredient converter
- Oven temperature
- Recipe scaler
Math:
- Scientific calculator
- Percentage calculator
- Fraction converter
Extras:
- Clothing size converter
- Batch convert (multiple values at once)
- Conversion chain (link conversions together)
You also get natural language input, currency rate alerts, widgets, Apple Watch support, and iCloud sync. Most people will never need more than this.
What Pro Adds (13 More Mini Apps)
Convert Pro unlocks specialized calculators for people who need them:
Finance:
- Mortgage calculator
- Loan calculator
- Fuel cost calculator
- Sales tax calculator
Home Improvement:
- Paint calculator (coverage for rooms)
- Tile calculator (flooring area)
- Concrete estimator
- Lumber calculator
Design & Fitness:
- Color converter (HEX/RGB/HSL)
- DPI calculator
- Screen size calculator
- Work days calculator
- Pace converter (running/cycling)
Who Should Upgrade
Pro makes sense if you fit one of these profiles:
- Homeowners — Planning a renovation? The paint, tile, concrete, and lumber calculators pay for themselves on one project.
- Designers — If you regularly convert colors between HEX and RGB, or calculate screen dimensions, these tools save time.
- Finance-focused — Mortgage and loan calculators are genuinely useful if you're shopping for rates.
- Runners/cyclists — The pace converter handles km/mile splits for training.
Or if you just want to support indie development. I appreciate that.
Who Shouldn't Upgrade
I'm not going to pretend everyone needs Pro:
- If you mainly use Convert for currency, tips, and cooking — free has you covered
- If you've never calculated paint coverage in your life, you probably won't start now
- If you don't work with color codes, you don't need a color converter
The free version isn't a trial. It's 18 complete mini apps that work forever.
No Ads, No Tricks
Convert doesn't show ads. Not in free, not anywhere. I hate ad-supported apps, so I didn't build one.
The business model is simple: free is genuinely useful, Pro adds specialized tools for people who need them. That's it.
Subscription or Lifetime
Convert Pro is available two ways:
- Subscription — Monthly or annual. Annual saves you money if you commit for the year.
- Lifetime — One-time purchase, keep Pro forever. Better value if you'll use it long-term.
I offer both because different people prefer different things. The lifetime option exists because some people (rightfully) hate subscriptions.
Get Convert on the App Store — start with free, upgrade if the Pro tools would help you.
