Ratings and reviews

I'm docking one star because the UI is ugly and because I can't switch from landscape to portrait mode when using the level. Other than that nitpickery, I'm really glad I paid for this because it's helped me a lot building and customizing bicycles. And it's comforting to know that there's stuff here I can use in the future, should the occasion arise. I hope the dev keeps up the good work and expands the tool set … lol and removes some of the UI's ugliness.

I looked at a lot of apps and it the best by far. I like that I can change the units for the level app, very few level apps support that. It is also great to be able to change the font sizesize, I don't know why so many of these apps use a microscopic font which is useless in the field. The level app does not support portrait mode, which is not a big deal but would be a nice option. I had a question for the developer and they got right back to me.

Please remove annoying popup about useless update. Thanks. PS: there is still features you can add. For example, it would be nice to customize colors UPD: Failed to update, removed, then failed to install. Such a usefull update, thank you
