Six LibreOffice Calc features handle the spreadsheet work most people think they need Excel for, and it is free

Goal Seek to regex How-To Geek's Tony Phillips shows Goal Seek solving backward from a profit target to the price per cup, pivot tables summarizing a long list by region or product, Data, Statistics, Regression returning R-squared, ANOVA, coefficients and p-values, the XLOOKUP, FILTER, UNIQUE and SORT formulas working with spill, recorded macros, and regular expressions inside Find and Replace at Ctrl+H; his own stated limits are that Excel gives more options for customizing and interacting with pivot tables and that Excel's VBA ecosystem is much deeper.

Two apps, one small model XDA's Nolen Jonker spent a month running Qwen 3.5 2B, Gemma 4 E2B and Qwen 3.5 4B on a base iPhone 16 with 8GB of unified memory, through Google AI Edge Gallery and Noema, and reports the local models handled 90% of the prompts he used to send to Claude and ChatGPT, with Qwen 3.5 2B reaching 32 tokens per second on short prompts and staying above 20 on longer ones; he is straight about the costs, since a phone realistically holds a 4k to 8k token context, 20 inference runs drain about 10% of an iPhone 16 Pro battery, research needing the live web still goes to the cloud, local chats stay on the device instead of following you to a desktop, and Noema is iOS only.

Unlock before you tap Android Police's Anu Joy turns on Require device unlock for NFC under Settings, Connected devices, Connection preferences, NFC so a contactless payment cannot clear on a locked phone, clears the lock screen Wallet shortcut under Settings, Display, Lock screen, Show wallet, limits where passes surface with Use passes across Google under Your data in Wallet, and removes cards no longer in use; her caveats are that the exact steps vary by device and Android version, and that deleting a card in the app on one device does not necessarily remove it from your Google Account, which is what payments.google.com is for.

Five services, one server How-To Geek's Nick Lewis lists what his family adopted without being asked twice: Jellyfin for movies, shows, music and photos on smart TVs, PCs, phones and browsers with no ads or subscription; Navidrome, a light music server speaking the Subsonic API so ordinary player apps can reach a ripped CD collection; Pi-hole on a Raspberry Pi Zero 2 W, roughly $20, blocking ads and trackers for every device on the network; Nextcloud in place of OneDrive or Google Drive; and Paperless-ngx, which OCRs receipts, tax records and medical documents into a searchable archive; his caveats are the honest ones, since Jellyfin transcoding wants Intel Quick Sync or a GPU and some clients still cannot play every format, a lone Pi-hole is a single point of failure, and the first pass of scanning an existing paper pile can take hours.
