Force Board vs Tindeg dynamometer?

For anyone who has been using one of these , which do you prefer......for measuring finger strength and training force, and ease of using the phone app for these?

........"Force Board" or "Tindeg" dynamometer?

thanks for any info or advice!  

I’ll bump this for you. I’d Like to know more about the force board. 

I have the Force Board. It’s been a game-changer from a finger-strength training and rehab perspective. Its data is well-visualized, and building protocols is breezy. It would be a hassle for repeaters (I just use a hang board), but love it for any strength or power exercises. It is also great for slowly reintroducing hangs to injured fingers.

It does cost $30 a year post-purchase for workout tracking and some other features, and I don’t think that it offers huge advantages over no-hangs with weights, if you have a good data monitoring system. If you’re looking for an easy way to quantify your finger training, though, it’s a great tool.

I have a tindeq that i basically never use apart from benchmarking myself occasionally because the Bluetooth is super finicky and it just got too annoying. It’s an older model and I think they might have improved the quality so ymmv.
