# PMB Documents vs Pure Synth® Platinum

The clearest difference is rating: PMB Documents at 4.8 against Pure Synth® Platinum's 3.6. PMB Documents also leads on review sentiment (89% vs 51%) and ratings volume (1K vs 54). Pure Synth® Platinum's advantage is ads (none vs shown) and update cadence (every 3 months vs every 15 months).

Both are free to download. PMB Documents sells 4 in-app purchases, starting at $2.99 per month and Pure Synth® Platinum sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
