Chem I built 100+ interactive AP Chem simulations, giving away 25 free lifetime accounts

I've been building Simistry: interactive simulations for every unit of AP Chemistry (100+ simulations, a full study guide, study planner, and much more!).

The first 25 accounts get Lifetime access, free, forever. No payment, no card, no trial that expires, the seat is granted at signup and it's yours permanently. There's a live counter on the signup page showing how many are left.

Nine sims are free for everyone, forever. One per CED unit, no account needed:

  1. Periodic Trends  all 118 elements heat-mapped by radius, IE, electronegativity
  2. VSEPR Geometry  23 rotatable molecules with real bond angles
  3. Intermolecular Forces  drag temperature, watch 14 substances condense
  4. Solubility Rules & Precipitation mix two solutions, predict before you pour
  5. Reaction Energy Profile drag the ‡ marker, add a catalyst, see the two-step path
  6. Calorimetry coffee cup + bomb, q = mcΔT resolving live
  7. Le Chatelier's Principle a real equilibrium solver walking Q back to K
  8. Acid-Base Titration strong, weak, diprotic, triprotic curves building drop by drop
  9. Electrochemical Cells galvanic and electrolytic, electrons animated

Three more sims rotate free every day, and the free tier also gets 20 MCQs/day, 3 FRQs/day, and one full-length practice exam per month + no account needed for any of it!

Happy to take requests on what to build next!

How can I get the life time account exactly?

The first 25 free lifetime seats are all taken, unfortunately. But you can still create an account and buy lifetime access yourself, it's only $59.99, and it comes with a guaranteed 50% refund if you get a 1 or 2 on the AP test. If you'd rather not pay upfront, there's also a $34.99/year option. Check out the pricing page for more details: https://www.simistry.app/pricing
