The slotho changelog: every release, newest first. If you are looking for what the app does today rather than how it got here, the slotho page is the place to start.
26.4 — the food before the feeling
17 September 2026. slotho now looks for the foods that turn up before a symptom, using only your own logs and only once there is enough evidence to say so. Digestion logging was rebuilt around it — six symptoms, each with its own severity — and a meal can now carry the place you ate it.
Two write-ups on slotho.io: slotho 26.4 — the food before the feeling, and where you ate it.
26.3 — the notes read themselves
7 September 2026. Workout notes are read aloud on Apple Watch when the set changes, in the language the note was written in. Guided breathing and meditation arrived, the evening card says what is still ahead of you, and Settings was reorganised so every setting has one home.

26.2 — the fast, read from what you ate
29 August 2026. A fasting schedule editor, with six stage markers that run off the meals you logged rather than a timer you have to remember to press. Around it: a today ring for the Home Screen, hydration that follows how much you moved, electrolyte cue cards and rebuilt monthly summaries.

26.1 — the rebuild
21 July 2026. slotho was rebuilt from the ground up around a single idea: see your whole day in one place instead of hunting through separate screens. The daily balance score, the timeline, the energy view and the redesigned logging all arrived together, and Pro became free for two weeks so people could try the parts that are paid.
Two longer write-ups cover this release: The new slotho: your whole day, in balance, and how the daily balance score is calculated.
Why the numbers jumped from 2.4 to 26.1
slotho moved to calendar versioning in 2026. The first number is the year, the second is the release within that year — so 26.1 is the first release of 2026, and nothing was skipped between 2.4.0 and it. The old sequential numbers below are kept exactly as they shipped.
