NOT ad free!
Response from developer
You were right, and I'm sorry. The listing said "no ads" while the free version showed a banner you couldn't dismiss. That copy was written back when the app genuinely had no ads, and I didn't update it when ads were added. That's my mistake, not a misunderstanding on your part. Rather than reword the description, I removed the ads. The next version, 1.5, is with Apple for review now: no ad banner and no ad SDK at all, on any tier. Nothing in the free version got worse to make that happen. Thanks for saying it plainly. It's the reason it got fixed.
