What Are Max Idle and Exercise Tree?

Max Idle and Exercise Tree are two apps from skorulis, an independent developer whose site describes its work as "focused apps, crafted with care." Max Idle is an idle game with a twist: it is, in the developer's own words, "actively trying to get you to go and do something else." Exercise Tree is a fitness companion still in development that is built around progression — you pick a goal and work through prerequisites. Both are listed on skorulis.com alongside DuskRoute, Fact Snack, and Joke Snack.

Max Idle at a glance

Max Idle is described on the site as an idle game where you "earn real time and add multipliers to get idle time." The core loop, as presented, is about accumulating time and stacking multipliers rather than completing a storyline.

What the site lists for Max Idle:

• Earn real time and add multipliers to get idle time
• Shops, achievements, and research labs
• No quests, just obligations

The "no quests, just obligations" line is the clearest signal of tone. The developer also writes, "I'm still not sure if this is a joke," which suggests the app is deliberately self-aware about the idle-game genre — a game that nudges you away from itself rather than pulling you deeper in. The site marks Max Idle as "Available now."

Who Max Idle is for

If you already play idle or incremental games and want one that plays with the genre's conventions — multipliers, shops, research trees — rather than a straight progression grind, Max Idle is the one to look at. If you want a narrative, quest-driven game, the site explicitly says there are no quests.

Exercise Tree at a glance

Exercise Tree is a fitness companion "built around progression." The site's summary: "Start easy and build up." You choose what you want to accomplish, then work through the prerequisites that lead there.

What the site lists for Exercise Tree:

• Organised exercise library with clear movement categories
• Progression from easy to expert
• Explanation videos for each exercise
• Pick what you want to accomplish and work through the prerequisites

The prerequisite structure is the defining feature. Instead of browsing a flat list of exercises, you start from a goal and follow a path — the "tree" in the name. The site marks Exercise Tree as "In development," so it is not presented as a finished, available product the way Max Idle is.

Who Exercise Tree is for

Exercise Tree suits someone who wants a structured route from beginner movements toward a specific goal, with video explanations along the way. Because it is still in development, treat the feature list as the intended design rather than a shipped, verified feature set.

How the two compare

The two apps sit at opposite ends of the same design instinct. Max Idle turns idle time into a mechanic and then jokes about sending you elsewhere; Exercise Tree turns movement into a progression path you climb deliberately. Both are framed as focused, single-purpose tools rather than broad platforms.

Practical notes before you try them

• Max Idle is listed as available now; Exercise Tree is listed as in development, so availability and features may differ from the descriptions above.
• The site does not state pricing, subscription terms, or platform availability for either app. Fact Snack and Joke Snack are described as having "zero ads and no subscriptions," but that wording is attached to those two apps specifically — do not assume it applies to Max Idle or Exercise Tree.
• For Exercise Tree, the explanation videos and exercise library are described features; since the app is in development, confirm what is actually included before relying on it for a training plan.

If your goal is a game, start with Max Idle. If your goal is structured exercise progression, Exercise Tree is the relevant one — with the caveat that it is still being built.
