This calculator app maybe I use it for nostalgia’s sake but I’ve had it on every android for the past 10+ years. It works great, launches instantly, and the ads were never more than a small banner at the top. I did buy the ad free version but it’s $2, no subscription or any bullshit, just a straight and honest scientific calculator.
Maybe not underrated because everyone should already be using it but KDE connect is a life changing app. So much functionality packed into a lightweight package. Just having a shared clipboard between my phone and laptop has been such a time saver every single day. If you don’t already have it, you should.
I agree steel frames are great, but trek, specialized and gt abandoned steel in the late 90’s. I love a good vintage frame, but for mtb the modern geometry is an undeniable upgrade.
High end: Orange cycles, Cromag, Ritchey, Chumba, Cotic.
Mid range: Kona, Marin, Surly, Niner.
Also: go tubeless and never buy an innertube again. I bought a 5 pack of tubes for emergencies and used 2 of them in the past decade. The sealant can be a royal pain in the ass, but it beats getting stranded out on the trail.
