Flux VS SmartSpin2k

Flux is free and open source: https://github.com/dvmarinoff/Flux

I need some app to do my planned workouts indoor. The problem is my smart trainer reads 40-50 watt lower compared to the powermeter I use outdoors, so doing workouts would make them way harder than they need to be. Zwift has a nice feature to adjust the power on the go, but it doesn't work in the background, and I am fed up with the app crashing mid-intervals. The Flux browser app (https://flux-web.vercel.app/) works great, simple and reliable, but you need to adjust the power every time you start a new interval, which is fine for longer ones, but impossible for shorter ones. Most of these virtual apps are quite expensive for the times I ride indoors, 2-3/month, and I honestly couldn't care less about the virtual stuff. I'd rather watch a tv show or something.

Flux https://flux-web.vercel.app/ can be used to create+run custom workouts. It's free, and you don't even have to install any software - it's a web app. I've used it once and can confirm that it works.

Since nobody has mentioned it yet: Flux. It just runs in a web browser: https://flux-web.vercel.app/

And we are not talking about a new application, the Companion app already manages to connect to trainers, it is implementing the workouts locally, something that if it can be done in an open source website like https://flux-web.vercel.app/ I don’t think should be too difficult for Zwift team

GoldenCheetah, or alternatively https://github.com/dvmarinoff/Flux or you can just use your headunit (assuming you have one)

Think OP is maybe talking about this? https://github.com/dvmarinoff/Flux

Edit: maybe this was it? https://github.com/doudar/SmartSpin2k I don't know what your enjoyment for DIY stuff is, but this is doable.

This can automate resistance adjustment - https://github.com/doudar/SmartSpin2k

It’s a device that goes on the knob of a spin bike and turns it into a smart trainer. The project is in its 4th year and 3rd hardware revision. We went from no pcb to a pcb that was a carrier board for dev kits to now a full custom pcb. It works great! https://github.com/doudar/SmartSpin2k

Schwinn IC4 is a good bike. I hear good things about the Echelon Connect Sport as well. Both can be turned into a smart trainer with a bit of DIY effort using a SmartSpin2K to control the resistance dial automatically. It's a fun little addon that improves the experience. Worked brilliantly for me since I've got a very small condo with no space to bring a bike upstairs and onto a trainer. The spin bike was way easier to dedicate the space to 100% of the time and my partner also gets to enjoy it

Check out https://github.com/doudar/SmartSpin2k and add automatic resistance to your spin bike. Everything you need to build your own, or a limited number of pre built kits are available!

If the recumbent has a knob-based resistance control like a spin bike, you can use a SmartSpin2K device: https://github.com/doudar/SmartSpin2k with power meter pedals. (There's also a retail competitor, IDK about patents and such, but I always favor the maker version.)
