Five modes, a hard case and real-time app tracking of where you brush make up the iO5's pitch. Oral-B's page is inconsistent about the handle itself: its feature list names an interactive display, while the product copy only describes LED mode lights, so the screen row is left blank here.

Best for: People who want Intense and Super Sensitive modes on one handle
Multi-signal pressure sensor. Oral-B's description: iO pressure sensor signals if you brush too hard, too soft, or just right.
ADA Seal listing: Oral-B iO Series on the ADA’s own product search.
These are facts about features and listings, not a statement that the brush prevents or treats anything. What a pressure sensor does · What the ADA Seal means
12 heads over 36 months at Oral-B's stated 3-month interval, less 1 head in the box. Head price: Oral-B iO Ultimate Clean 9-count, $64.99 on oralb.com. How this is worked out
What the extra money buys: Same iO magnetic drive (Oral-B's name for it; no speed published) and a pressure sensor as the Oral-B iO Series 3; the extra $60 buys 2 more modes, app tracking and a travel case. See the Oral-B iO Series 3.
The two lists above are drawn from the maker’s own pages and prices, not from owner reports. Where owner discussion has been read it appears in its own section below, so the two are never mistaken for each other.
No owner discussion has been read for the Oral-B iO Series 5 yet. This section stays empty until there is something real to put in it.
