Hemiscend is an independent iOS studio making focused tools for health, attention, memory, and the quiet systems behind daily life.
Our Apps
150 Club
An aging radar for the longevity era. Track biological age estimates, aging rate, Apple Health trends, home health readings, lab report markers, and family health signals in one private place.
Seelit
A mental imagery training app for people with aphantasia and hypophantasia. Your imagery isn't broken — it has a shape. Seelit helps you find it, then build from there through guided daily sessions.
Patchee
A freeform canvas for iOS. Drag, drop, and arrange notes, countdowns, flashcards, and more into a personal space that works the way your brain does — not the way a spreadsheet does.
About
Hemiscend is an independent iOS studio building apps for people whose lives don't fit the standard mold, from longevity tracking to memory, focus, imagery, and personal systems.
Every app starts from a real problem. We care about craft: the details in the interaction, the honesty in the copy, and the respect for the person using it.
