Free during beta. Then free, monthly, or one-time.

Right now goal-grids.com is in beta, and it's free for everyone using it. If you sign up before the beta ends, you keep it free forever. No surprise paywall, no email a year later asking you to upgrade. You're in.

When the beta wraps up, new accounts get a free plan with up to 3 grids, which is plenty if you're tracking one or two things at a time. If you want unlimited grids, there are two options: €1.99 per month, or €20 once for lifetime access. Same features either way, the only question is whether you'd rather pay a little each month or just get it over with.

I might still tweak the pricing before launch, but I won't pull the rug on anyone who already signed up. What you sign up for is what you keep.
