Apps I've designed & built

gymnerd

A field manual for strength. 1,324 exercises indexed by muscle, movement pattern and equipment; an anatomy navigator that maps every muscle to the exercises that train it; and a program builder whose muscle coverage you can see before you commit. Built for trainers, free to use.

Pilates with Chawanee
Visit livePilates, taught plainly
My teaching practice, online. A bilingual (TH/EN) site built around the five STOTT PILATES principles — breathing, pelvic and rib cage placement, scapular stabilization, head and cervical placement — each broken down with the cue I actually use in class, plus essays to revisit between sessions and booking for private, duet and small-group classes.
Ground
Visit liveBreathe & reset
A minimalist breathing and grounding app for calming the nervous system. Guided breath pacing wrapped in a deliberately quiet, zen interface — restraint in the design serving the calming purpose.
JumSub
Visit liveจำศัพท์ จำนาน ใช้งานได้จริง
An English vocabulary trainer for Thai speakers, with 1,137 words spanning Basic, Intermediate, Advanced and IELTS Band 7+ tracks. Daily goals, streaks and XP levels turn spaced-repetition drilling into a habit.
