Trump's actions also led to lawsuits, and the federal courts' pausing enforcement of his directives.
TikTok, owned by Beijing-based ByteDance Ltd., declined to comment.
Biden's new executive order revokes the WeChat and TikTok orders issued in August, along with another in January that targeted eight other communications and financial technology software applications. However, the new order did not address deadlines set by the Committee on Foreign Investment in the United States (CFIUS) in the Trump era for ByteDance to divest from TikTok.
Administration officials said Wednesday that TikTok continues to undergo a separate review by a government panel that reviews cross-border transactions.
The officials say they remain concerned about security risks from Chinese and certain other foreign-owned apps but that the executive orders signed by Mr. Trump were effectively unenforceable.
Specifically, the Commerce Department will be required to investigate apps "involving software applications that are designed, developed, manufactured, or supplied by persons that are owned or controlled by, or subject to the jurisdiction of a foreign adversary".
The new administration's framework to evaluate apps will be flexible, allowing it to take a tailored approach that addresses the specific risks of each company, one United States official said.

Students in Windsor-Essex and across Ontario are being forced to continue at-home learning for the rest of the academic year. He also said teachers and eligible students will all be offered two doses of the COVID-19 before in-person learning resumes.
Biden's move to drop Trump's executive actions had been expected since at least February, when the administration put the Trump-era orders on ice.
The new order also calls for a security review of the apps.
In March, the US joined allies in imposing sanctions against Chinese officials engaged in the mass incarceration of mainly Muslim ethnic minorities in the Xinjiang region.
A second federal judge later fully blocked the Trump administration's attempt to ban TikTok in the USA, finding that Trump overstepped his authority in using emergency economic powers to put the popular app out of business. Some US lawmakers have suggested that China could seek to exercise influence over popular apps like TikTok to spread disinformation or engage in censorship. Tuesday the Senate approved a $250 billion bill boosting government spending on technology research and development amid rising competition from China and other nations.
Senior administration officials told the AP that the department will issue recommendations on how the personal data of Americans, especially those using popular Chinese apps, could be protected.
The president will meet overseas with European and North Atlantic Treaty Organisation leaders this week to discuss actions the worldwide community can take to hold China more accountable.
The TikTok order alleged that the app "automatically captures vast swaths of information from its users" which "threatens to allow the Chinese Communist Party access to Americans" personal and proprietary information - potentially allowing China to track the locations of Federal employees and contractors, build dossiers of personal information for blackmail, and conduct corporate espionage'.
