O Crismob This is a Brazilian website about mobile applications. Here I publish guides on what each application does, who it's for, and how to use it: cattle weighing and rural management, cleaning and optimizing device memory, streaming movies, dramas and soccer, chat and dating, photo recovery, Wi-Fi, GPS, health and everyday utilities. The site has been publishing since May 2024.
Who writes
One person: Rodrigo Oliveira. There is no editorial staff, no team of experts, and no contributors. I am the only registered user on the site, since May 29, 2024, and I sign all published content. As of August 2026, there are 255 pieces of content online, including articles and pages recommending apps. When a text contains an error, the error is mine, and the request for correction goes to [the relevant authority]. [email protected].
How do I verify information from applications?
Before publishing, I check the app's official listing on Google Play or the App Store: exact name, developer, availability in Brazil, whether it's free or paid, if it has in-app purchases, permissions requested, and what the official description promises. Ratings, price, size, and feature list change without notice, and sometimes even from country to country. The store is the final source: if what you see there differs from what's here, the store is the one that counts.
I don't test all the apps I mention. Much of the information comes from the store's listing and the developer's documentation, and that's what they describe. I don't invent ratings, download numbers, testimonials, or awards. I also don't promise results: none of the apps recommended here guarantee weight loss, making money, eavesdropping on other people's conversations, or recovering deleted files.
How the site sustains itself
With programmatic advertisingThe ad spaces are sold through automated auctions via Google Ad Manager. Some of the traffic comes from ads that I buy myself. That's where the money comes from to pay for hosting, tools, and the time I spend writing.
Advertising doesn't buy recommendations. Advertisers don't choose the topics, don't review the text, and don't decide which app appears in which list. The ad you see next to an article is served through an automated auction and has no relation to what the article says. If there is ever sponsored content or an affiliate link, that will be clearly stated on the page itself, before the text.
Errors and corrections
Content about an app gets old quickly: the app goes offline, changes its name, becomes paid. Found something wrong? Write to [email protected] with the page address and the excerpt; confirmed correction is made in the text itself. See also the Privacy Policy and the Terms of use.
