Why it exists
Timer apps weren't made for teaching.
You think in blocks, exercises and sides. Your timer thinks in a flat list of intervals. So you retype every move twice, do the block math in your head, and keep your phone close in case something goes wrong.
shakeshift. is built around how a class is actually taught.
What's inside
Four things no timer app does.
Cues that live inside the exercise.
Drop a 90° hold at 1:30 into a 3:00 lunge. The lunge stays 3:00, and your watch gives the hold its own countdown and tap.
Read the room.
Tap Abandon Sequence to drop the planned moves and freestyle. Your block timer keeps running, and Back to Plan brings them back.
Block math, done for you.
Every block shows 12:30 of 15:00 as you build, with a flag for short, on target or over.
Taps you can tell apart
A different tap for each new exercise, cue, countdown and block.

The founder
Built by a coach, for coaches.
Hi, I'm Maddy. I've taught more classes than I can count off timer apps that were never made for coaches. We all rig them to work, and they still get in the way.
I built shakeshift. because I needed it. I use it to teach my own classes, and a group of coaches has been shaping it in beta since October.
Maddy, founder of shakeshift.

FAQ
Questions coaches ask.
Do I need an Apple Watch?
You can build classes on your iPhone without one. Teaching from your wrist is where shakeshift. shines.
What type of coach is it for?
Any group fitness coach or instructor who teaches timed classes: Pilates, barre, HIIT, strength, cycle, bootcamp and more. If your class runs in blocks of timed exercises, shakeshift. is built for you.
Do I need to keep my phone nearby while I teach?
No. Once you send a class to your watch, it runs on its own. Lowering your wrist never pauses anything.
Can I import my exercises?
Yes. Bring your exercise list in from an Excel or CSV file, including times, sides and equipment. From Google Sheets or Numbers, export to Excel or CSV first. Your moves land in your exercise library, ready to build classes from.
What happens to my data?
Your classes stay on your iPhone and Apple Watch. There are no accounts, no ads and no tracking. Read the privacy policy.
How do I cancel?
Open Settings on your iPhone, tap your name, then Subscriptions, and choose shakeshift.
