Ditch Google Maps? The Best FOSS Offline Map Apps in 2026

Illustration: open-source offline map apps

Google Maps is excellent — and it knows exactly where you go, when, and how often. If that trade makes you uneasy, a mature ecosystem of free, open-source, privacy-respecting map apps is ready to take over, and most of them work fully offline.

Why leave Google Maps

Two reasons: privacy (your location history is a detailed diary you may not want stored) and offline reliability (downloaded maps work in dead zones, on planes, and abroad without roaming). FOSS map apps are built around both.

The top options

  • Organic Maps — fast, clean, privacy-first, great for hiking and driving; fully offline.
  • CoMaps — a community-driven map app in the same family, focused on staying open and ad-free.
  • OsmAnd — the power user’s choice: dense features, detailed offline navigation, endlessly configurable.

All are powered by OpenStreetMap, a free, crowd-sourced map of the world that anyone can improve.

The trade-offs

You’ll give up some polish: live traffic and business hours aren’t as comprehensive, and search can be less forgiving. For everyday navigation, hiking, and travel, though, they’re more than good enough — and they keep your movements to yourself.

Bottom line

You don’t have to quit Google Maps entirely. But keeping a FOSS offline map installed is smart insurance for privacy and dead zones alike — and you may find you reach for it more than you expected.

How I used Google Sheets and Apps Script

Google Sheet is one of the most powerful spreadsheet application that exists online, rivaling with Microsoft's Excel. One of the main strengths is its strong support for collaboration with other users, much easier and popular than collaboration tools with Microsoft Office. Aside from plain spreadsheet, it also supports extensions such as macro. If you are familiar with macros on other office tools, they work almost the same. However, the most extension I use and tinker with is the Apps Scipt . Apps Script Extension One of the challenges I faced recently is how do I track or monitor reports in our department if they are submitted on time or worst, forgotten due to lack of better monitoring tools. So I thought if there can be simple applications that can be deployed or use by a more general user to allow reminding periodically what reports are approaching due dates or those that are past dues. Then I looked for a way, instead of creating a full blown app from scratc...

Sluicegate Tutorial with FlowStudio

This walkthrough shows how to use FlowStudio ’s sluice gate (rectangular channel) worksheet: upstream pool depth from specific energy, downstream gradually varied flow, and—when the case allows— hydraulic jump placement plus an empirical jump length (SI units). Open FlowStudio → https://flow.syncster.dev What you are solving A bottom sluice in a wide rectangular channel passes a discharge Q . The worksheet assumes a contracted depth at the vena contracta, y 2 = C c a , where a is gate opening and C c is a contraction coefficient (often near 0.6–0.65). From specific energy matching between the upstream pool and the contracta—together with a check against uniform normal depth y n for the approach channel—the sheet finds upstream pool depth y 1 . Downstream, it integrates Manning-based gradually varied flow from the gate. If the contracta is supercritical and you set a subcritical tailwater y t (or...

Automate Sending Email with Apps Script and Google Sheet

Introduction It has been too long that many people uses Microsoft Excel in day-to-day computing tasks. It's so big that it almost resemble a programming language where non-technical people can create their own spreadsheet programs. It has many uses with just the default grid-type data entries. But Microsoft Office developers did not stopped there. They gave it more power by adding a scripting capability to it with VBA or Visual Basic for Applications. Most of the office apps of Microsoft has this VBA at their disposal but I most used it with Microsoft Excel. It was the most appropriate application for me to use it. But then come the big competition. I'll skip the open source apps that may compete with Microsoft Office and go directly with the big one. This is the Google Sheet from Google. Introducing Google Sheet Google Sheets is an online spreadsheet application that allows users to create, edit, and format spreadsheets to organize and analyze information....
