Sent2X

This afternoon I shipped a "fix" for a one-frame jump on iPhone. Seven minutes later the input sat under the keyboard on Chrome and Safari.

This was not the product. It was the chat bot on sent2x.com — the small box in the corner, a side project on the same website. People open the site on a phone, type, tap 完成 (Done). I use that box myself. That is how I saw the jump.

The original bug: tap Done, and the composer snaps to the bottom, jumps up, then settles.

Chrome for iOS and Safari do not agree on what a keyboard is. Safari keeps the layout viewport and shrinks the visual one. I measured 714 minus 376: 338 pixels of keys. Chrome shrinks the layout viewport itself. While the keys are up the reading is 414 minus 414: zero. After Done, Chrome grows the layout first. I measured 741 while the visual viewport was still the keyboard band at 414. That difference is 327. It looks exactly like a Safari keyboard coming up. If you size the panel to it, the input jumps.

I "fixed" the jump by locking the panel to the large viewport so it could only get taller, never shorter. The jump died. Then both keyboards covered the input, and Chrome's header started sliding.

The version that works is dumber. The cover follows the layout viewport again. After Done, I ignore that fake 741−414 reading until the user taps the field. Two production deploys, 18:52 and 18:59. The second one is live. I checked it on the phone. Done no longer jumps, and the field sits above the keys.

The site that bot sits on is Sent2X. The bot is a box for talking to the site. The product is for a small X account: it finds threads where someone already asked the thing you can answer, writes a first draft inside X's reply box, and puts your own posts on a schedule. It stops at the draft. I still press send.

I count one number on that product this week: how many people came back and used it again. That number is 1. 32 have signed up. 9 opened it. The other 23 never opened it. None of the 32 are tagged indiehackers.

The bot is a corner of the site. The thing to try is Sent2X. Free is 10 scheduled posts a month. No card.
