Those are the four examples How-To Geek writer Jorge A. Aguilar described on August 21, 2026. They are small custom utilities, not proof that generated apps are reliable, secure, or free of ongoing costs.
What the four custom apps do
A focus timer that feels like a game
The timer turns work sessions into a creature-raising game: complete a session to earn experience, food, or stat upgrades; skip sessions and the creature may lose health. Aguilar described his own creature, a slime named Jasper. The appeal is that the reward system can reflect what motivates you, rather than requiring you to adapt to a generic timer.

A plain-language hotkey and macro builder
A proposed “Universal Hotkey Script Compiler” translates instructions into keyboard shortcuts and repetitive actions. For example, you might ask it to recognize a key combination, open VS Code, wait, and type a command. This kind of automation is especially dependent on precise instructions and the operating system it is meant to run on.

A browser-based resizer can apply the same dimensions, output format, and compression settings to multiple selected images. Aguilar describes building this kind of utility with HTML, CSS, and JavaScript, then choosing image files from a folder. The source describes the intended workflow; it does not report speed tests or establish that every generated version processes files safely.

A photo gallery with chosen controls
A custom gallery can prioritize the features you actually use, such as viewing several images, zooming, and supporting transparent PNG files. The design can keep image-changing controls separate from ordinary navigation, reducing the chance that browsing actions alter a file.
How to get a useful first version
Aguilar’s approach is to explain the desired result in detail, ask Claude for ideas, and iterate on the first version. A concrete example of a project or interface you like can help convey the goal. Treat the output as a draft to review, not finished software guaranteed to work correctly on the first attempt.
Rank #2
- Describe the job, not just the app category. For a timer, specify session lengths, breaks, what counts as completion, and how the creature changes. For an image tool, state the target dimensions, formats, and compression options you need.
- Define the actions and platform for automation. Say which operating system the macro builder should support. Spell out what words such as “press,” “open,” “wait,” and “type” mean, and describe the order and expected result of each step.
- Ask for ideas, then choose deliberately. Have Claude suggest features, but keep only those that fit your intended workflow. Extra features add complexity and can make the tool less predictable.
- Try the app with harmless examples and refine it. Report specific failures or confusing behavior, then ask for a targeted change. Check that the fix works without breaking other actions before relying on the tool.
What “local” processing does—and does not—mean
The article presents local browser processing as a privacy-oriented goal for the macro builder and image utilities: the tool should run on your device rather than send sensitive paths or image files to a server. That is an implementation aim, not a security audit. Generated code may behave differently than intended, so inspect it for network requests and test it with non-sensitive files before using it with private photos, passwords, or consequential workflows.
Is building them really free?
Aguilar reported that the projects could be made with Claude’s free plan and described the work as achievable over a free weekend. Those are his claims in an August 21, 2026 article, not guarantees about your time, equipment, or Claude’s current plan limits. The account supplies no measured app-performance results or figures for subscription savings, advertising avoided, or time saved. Consider the time needed to build, test, and maintain a custom tool alongside any app-store alternative.
