I rely on a selection of everyday apps that I use across my phone, tablet, and laptop. Since my devices operate on different systems, I prefer cross-platform apps that are compatible across operating systems.
Here are few of them, in no particular order.
Note Taking / Productivity
Obsidian (Free): My note taking app of choice. Though not entirely cross platform, you can surely find ways to get it to work in different OS. I prefer the light-weight, secure and markdown style of obsidian over other note taking apps.
Todoist (Free): Best to-do list app out there. Most people needn’t look beyond the free version of the app. It does almost all the things right and the natural language processing capabilities makes it awesome!
Streaks (One-time fee): This app is mac / iOS only but made this list because of its slick interface and usability. None of the android apps I tried was doing what this app is doing. Certainly helped me maintain my habit streak!
Notion (Freemium): If you really want a note-taking app that works seamlessly across platforms (app and web), then notion would be your best bet. It does not, however, work offline.
Communication
Gmail (Free): It comes by default with android phones and is a few clicks away in iOS — and there is very little to speak bad about gmail.
WhatsApp (Free): Chats, voice calls, video calls. Spams by businesses and being owned by Facebook are the only negatives for me in WhatsApp.
Telegram (Free): More secure than WhatsApp (apparently) and I use this because of some of my friends group and my apartment group being present in telegram.
For work, I use: Google Meet (Free), Slack (Free)
Web Browsing
Brave (Free): I have started using brave over chrome (which again is a good choice, come by default on android phones and free) recently and have started to like the transition. The ad blockers in brave is awesome.
Instapaper (Free): Save articles to read offline later — must have if you consume a lot of content. Pocket is another good option.
Consumption
Kindle (Free): I use this primarily on my iPad, but it is good to know that I can have my books in my phone or laptop whenever I need them.
Audible (Subscription): I use audible extensively to listen to books during my commute to work. For Rs.199/month, audible has drastically improved by consumption. This has ensured I read / listen to at least 12 books a year.
Feedly (Free): A good RSS reader and my way of consuming information from the sources I like.
Spotify (Free / Subscription): My app of choice to listen to music — works well between operating systems.
Utility
Microsoft lens (Free): My go-to app to quickly scan documents
Snapseed (Free): Use snapseed to quickly edit photos. Light-weight and user-friendly.
