An interesting way to gamify plank training if the phone app format appeals to you, though it depends on the app working smoothly and there is no owner feedback here yet.

Overview
The Stealth Core Deluxe, model Core Trainer Plankster, is a plank position core trainer that pairs with a free iOS or Android app, translating your body's movement into on screen game controls rather than counting reps. It reads motion through your phone's own sensors while the phone sits on the trainer during a plank.
Despite how it is filed in this catalog, this is not a balance board: it is a stationary plank base with 360 degree motion designed to be used in a plank position, not stood on. The app ships with four included games plus a leaderboard and challenge feature, and no subscription is required for the base game set.
- Phone app controlled plank core trainer
- 360 degree multi directional motion
- 4 free games with worldwide leaderboard
- Sessions pitched at about 3 minutes a day
Who it's for
Suits people who find standard plank holds tedious and want a game layer to hold their attention for short daily core sessions. Not a fit for anyone wanting a literal standing balance board or a subscription free training log without a phone involved.
Pros and cons
- Turns short plank holds into a phone controlled game
- 360 degree motion sensing for core work from multiple angles
- Four games and a leaderboard included at no extra cost
- Requires a phone and the companion app to function as designed
Performance notes
The base reads multi directional motion during a plank hold and feeds it to the connected phone's motion sensor, with the app translating those movements into game actions. Sessions are pitched at around three minutes a day rather than extended holds.
