Notes
- 1.Display type. Small monocular HUD screen mounted at the edge of the right lens, comparable in size/resolution to a Garmin Varia Vision unit per an independent reviewer's side-by-side comparison [REVIEW, Slowtwitch, 2017]; paired with a six-axis accelerometer for lap/turn/stroke detection and an optical heart-rate sensor at the temple [NEWS, New Atlas, 2017-10-23; REVIEW, Slowtwitch, 2017]. Four configurable screens of four data fields each (lap count, lap time, distance, heart rate, calories, among 23 total data points) [REVIEW, Slowtwitch, 2017].
- 2.Water protection. No formal IP rating found; charges via a waterproof micro-USB port, implying the unit itself is designed for underwater use without a separate rating being disclosed [REVIEW, Slowtwitch, 2017].
US$199 was the early-bird pledge on Indiegogo in 2017. New Atlas cited a planned US$395 retail price and Slowtwitch US$399; no source confirms the product was ever sold at either.

Our review
For
- The campaign specifies a six-axis accelerometer and a temple-mounted heart-rate sensor tracking up to 23 data points.
- Four configurable screens can show four data fields each at once, per the campaign page.
- The unit charges through a waterproof micro-USB port, per the campaign specifications.
Against
- No SDK, API or developer information is listed for this device anywhere in the campaign materials.
- The device was never confirmed sold at retail: only a 2017 pledge of US$199 exists against a projected US$395 to US$399 retail price.
- Both of the maker's known domains, fisically.com and zwim.co, are dead today, and no source confirms units ever reached backers.
- Battery life is rated at only about four hours per charge, per the campaign specifications.
No independent review of this device has been found as of September 6, 2026. Zwim is a clip-on head-up display meant to attach to a swimmer's own goggles, created by triathlete Taegoo Kang under a company identified on its own Indiegogo page as Fisically Inc. The campaign specifies a small monocular screen on the right lens, a six-axis accelerometer and a temple-mounted optical heart-rate sensor, showing up to 23 data points such as lap time, distance and heart rate across four configurable screens.
No SDK, developer program or API is listed anywhere in the campaign materials, and no later documentation site has been found; the module is presented strictly as a closed, single-purpose swim computer, not a platform to build on.
The 2017 Indiegogo pledge price was US$199, against a projected retail price of US$395 to US$399 once shipped; nothing found in this research confirms the module was ever actually sold at either figure. The unit charges over a waterproof micro-USB port and is rated for about four hours per charge, but both of Fisically Inc.'s known domains are dead today, with no source confirming any unit ever reached a backer.
Verdict
No independent review of this device has been found as of September 6, 2026. Zwim's 2017 Indiegogo campaign promised a clip-on monocular display for swim goggles with about four hours of battery per charge, but its own domains are dead today, and no source confirms it ever shipped to a backer.
