LeanFPS is free to use. LeanFPS Pro unlocks the tweaks that run while you play and the per-genre game profiles, for a single $19 payment. Your first three games get Pro for free so you can judge it by your own FPS numbers.

Everything in Free, plus 11 tweaks:
LeanFPS Pro is a license key, not a subscription or an account. After you pay, the key appears on this page and in your inbox. Paste it into LeanFPS with the email you bought with, and Pro switches on for that PC.
The key works on up to three PCs at once. Moving to a new PC takes one click on the old one, or one click on the license page. LeanFPS keeps a signed license file next to its settings, so Pro keeps working offline and never phones home while you play.
1 of 3 PCs in use. Reinstalling LeanFPS on the same PC does not take a new seat.
Simulated. The rules are those of the LeanFPS Pro plan: 3 PCs, renewal every 7 days when online, up to 30 days offline.
A game optimizer does its work on your PC. There is no server cost for applying a tweak or measuring FPS, so we do not think a monthly fee is fair. Comparable tools charge between a one-time $57.77 and monthly plans; LeanFPS Pro is $19 once, and the free version stays useful on its own.
After the trial ends, game detection, FPS measurement and the core system tweaks keep working. Pro tweaks show a lock instead of disappearing, so you can still read what each one does on the Windows gaming tweaks page. Nothing you turned on is left half-applied: locked tweaks are switched back off and restored.
Already bought? Find your key or manage your PCs. Write to contact@leanfps.com. A person answers, usually within two working days. You can also read the terms and privacy policy, or go back to the LeanFPS game optimizer home.
No. LeanFPS Pro is a single $19 payment. Updates to the app are included; there is no monthly fee and no renewal.
The first three games you play with LeanFPS run with every Pro tweak switched on, so you can compare your FPS and 1% lows. After that, the free tweaks keep working and Pro tweaks are shown as locked.
Up to three PCs per key. To move Pro to a new PC, click Remove Pro from this PC in the old one, or remove it on the license page with a link we email you. No support ticket and no motherboard-locked licence.
If LeanFPS Pro does not help on your PC, email us within 14 days of purchase and we refund the full amount. No questions asked.
Pay on this page with your email. Your license key appears here and arrives by email. In LeanFPS, click Enter key, paste the key and type the same email. No account and no sign-in.
Only to activate. After that LeanFPS checks a signed license file on your PC, renews it in the background every 7 days when you are online, and keeps Pro working for up to 30 days offline.
Go to the license page, enter the email you bought with, and we email every key it owns. The same page lets you see and remove the PCs that use your key.
