Huge improvement over free version, VERY useful

I used to use the free version and it was interesting but almost useless in determining how to adjust the bike. The Elite version are $10 well spent. The automatic detection of the dots and the dynamic measurement are amazing. The report comparing measurements between different settings is extremely useful. Mist of all, the feature to see the effect of adjusting specific settings (e.g. seat height, front/rear position) is truly amazing! Fantastic tool, highly recommended!!

This was my first time using a bike fitting app. I figured I could save some money and gain some knowledge in the process. It wasn’t too difficult to set up and pretty easy to use. The only issue I had was the placement of a few of the markers (stickers). I wish there was A little better explanation on where they go with maybe a few better pictures showing placement. I discovered that a simple inaccurate placement of a sticker or two could throw off all the measurements. The upper leg placement and the shoulder ones seem tough to get accurate. Other than that I’m pleased with the app

Just keeps getting better!

This app has been amazing, and it just keeps getting better. They” new auto-locate feature to find reference points is superb and shockingly accurate. While BFF Elite won’t replace the knowledge of professional bike-fitter, it will substantially increase your comfort and efficiency on the bike. Not everyone needs an expensive professional fit anyway, but almost everyone can benefit from the app. Highly recommended!
