Best productivity apps for Android in 2026: 9 picks for sellers

If you sell from an Android phone, your day happens in the gaps. You finish a call in the car, walk out of a showroom, or wait ten minutes in a client's lobby. A productivity app earns a spot on your home screen only if it works in those gaps, one-handed, before the next thing starts.

So every app here had to survive a week with three appointments a day and twenty callbacks:

1. You can capture a promise in under a minute, from a widget or by voice, without opening three menus.
2. Every follow-up gets a date and a reminder before you start the car.
3. The features that matter work on Android. Some apps keep their best tricks for the iPhone, and we say so where they do.
4. It opens, edits or signs the quotes and forms buyers send you.
5. The free version holds a real selling week, or the paid one costs less than one lost deal.

We read, we didn't test. Every fact below comes from the app maker's own site, help pages and Play Store listing, which is why you won't see star ratings we'd have had to invent. Prices are in US dollars as of October 2026 wherever the app's own page shows them. Where a page prices by country, we send you to it.

Start with TickTick if you want one app for follow-ups and your calendar. If you won't spend anything, Google's own apps at 3, 4 and 6 plus Focus mode at 9 cover most of a selling week for free.

1. TickTick: best for most people who sell

TickTick puts a to-do list, a calendar view, a habit tracker and a Pomodoro timer in one app. Its Play Store listing says it reads due dates and alarms out of what you type or say, so "call Dana Friday 10am" lands on Friday at ten. A home screen widget shows today's tasks and adds new ones without opening the app.

The free plan gives you 9 lists, 99 tasks per list, 2 reminders per task and 5 habits, with a basic calendar view. The paid plan is US$49.99 a year and raises those limits to 299 lists, 999 tasks and 5 reminders, with more calendar views and task durations. Its features page also lists a constant reminder that keeps ringing until you tick the task off.

Pick it if you want this week's follow-ups, your calendar and a timer for the calling block on one screen. Skip it if you want a reminder the moment you pull up at a client's office, because TickTick lists location reminders for the iPhone only.

2. Todoist: best for talking your follow-ups in after a meeting

Todoist's Quick Add reads a date out of the sentence you type. Its Ramble feature does the same with your voice. Todoist's help page on Ramble shows tasks appearing in a preview while you talk, with dates and priorities, and a Ramble widget you can put on your Android home screen or lock screen. You say "send the Tans the revised quote Thursday at 10, call Marcus about the site visit Monday", and two dated tasks are waiting.

The free Beginner plan has 5 personal projects, Smart Quick Add and task reminders. Ramble on the free plan is 10 sessions a month, and a session counts only when Todoist finds a task in it. Pro is US$5 a month billed yearly, or US$7 month to month, with unlimited Ramble, 300 projects and a calendar layout.

Pick it if you drive between appointments and would rather say a promise than type it. Skip it if you'd use voice more than ten times a month and won't pay, because the free sessions run out.

3. Google Keep: best free notepad for the minute after a call

Keep holds notes, checklists and voice memos. Its Play Store listing shows no in-app purchases, and it shows widgets that pin a note to your home screen. Pin the note with your answers to the objections you hear most, so it sits one tap from the dialer when a buyer says the price is too high.

Keep's reminders are time-based. Google's Keep help says a reminder rings at the time you set and again 24 hours later, and it shows up in Google Tasks and Google Calendar too.

Pick it if you want a free place for scripts, prices and quick notes between calls. Skip it if you need every note filed under the client it belongs to, because Keep has labels and colours but no page per person.

4. Google Calendar: best free booking page for a phone-first seller

Google Calendar comes on most Android phones, and it does one thing a seller wants badly: a booking page. On a free personal Google Account you get one booking page, where a buyer picks an open slot and the meeting lands on your calendar.

The catch is where you build it. Google's setup page says you can't create an appointment schedule in the Calendar app for Android. Set it up once on a computer, then paste the link into chats from your phone for as long as you like. More than one schedule, automatic email reminders and taking payment need an eligible Google Workspace or Google One plan.

Pick it if most of your first meetings are one kind of call and you want the buyer to choose the slot. Skip it if you run three kinds of meeting and want a separate link for each, since the free account stops at one.

5. Microsoft 365: best if your quotes are Word and Excel files

Word and Excel run on Android, and a phone is the cheap way to use them. Microsoft's support page says that without a qualifying plan you can still create, view and do basic editing of personal files on screens up to 10.1 inches, which takes in every phone on sale. An Android tablet bigger than that needs a qualifying plan before you can change a file.

Selling on your own and editing on a big tablet too? Microsoft 365 Personal costs US$99.99 a year or US$9.99 a month.

Pick it if your price list is an Excel file and you change a number while the buyer waits. Skip it if your quotes sit in a work account with no qualifying plan, because the free editing covers personal files and accounts only.

6. Google Drive: best for scanning a signed form

The Drive app on Android turns your camera into a scanner. Google's Drive help says it saves receipts, letters and statements as searchable PDFs, and that the web version of Drive can't scan at all. Docs and Sheets open from the same place, so the quote you send and the form that comes back live side by side.

Every Google Account comes with up to 15 GB of storage, shared across Drive, Gmail and Photos. More space is a Google One plan, priced in your own currency on that page.

Pick it if buyers still hand you paper, and you want it filed. Skip it if your phone's photos already fill the 15 GB, because scans share that space.

7. Adobe Acrobat Reader: best free app for getting a PDF signed on your phone

A buyer emails the order form. You open it in Acrobat Reader, type into the boxes, sign with your finger and send it back.

Reader is free. Need to rewrite a clause, or turn the PDF into a Word file? That's Acrobat Pro, priced by country on Adobe's pricing page.

Pick it if forms and order sheets come to you as PDFs that need a signature. Skip it if you need to rewrite a clause in a contract on the go, because that's a paid plan.

8. Notion: best for a team playbook every rep opens on the phone

Notion holds pages and simple databases. A small team keeps its talk track, price rules, answers to common objections and a page for each big account there, and every rep opens it on the phone before walking in.

Notion's pricing page says a free workspace you use alone takes as many pages and blocks as you like. Add teammates and the free workspace gets a block limit. Plus is US$10 a seat a month, and free uploads stop at 5 MB a file.

Pick it if you run three or four reps and want one place they check before a meeting. Skip it if all you need is a list of follow-ups, since a task app does that with less setup.

9. Focus mode: best free way to protect your calling block

Focus mode is part of Digital Wellbeing, built into many Android phones. Android's help page says you choose which apps to pause, and while Focus mode is on you can't open them and get no notifications from them. You can put it on a schedule, and Take a break lets you back in for a few minutes.

Pair it with Do Not Disturb. Android's Do Not Disturb settings let you allow calls from chosen people, and a repeat-caller switch lets a call through when the same person rings twice in 15 minutes. A buyer who really needs you still gets through.

Pick it if your phone steals the first hour you set aside for calls. Skip it if you can't find Digital Wellbeing in your phone's settings, since Google only puts it on some phones.

Google and Adobe set paid prices country by country, so for those three rows, check the app's own page before you pay. The rest are in US dollars as of October 2026.

The free stack is enough while every live deal fits inside its limits. Count yours before you pay for anything, because each free plan stops somewhere different:

• TickTick: 9 lists and 99 tasks in each, with 2 reminders per task.
• Todoist: 5 projects and 10 voice sessions a month.
• Google Calendar: one booking page.
• Google Drive: 15 GB, shared with your photos and email.
• Notion: no limit alone, a block limit once a teammate joins.

Here's a stack that costs nothing. TickTick's free plan holds the follow-ups while Keep holds your scripts and prices. Calendar's booking page takes first meetings, and Drive and Acrobat Reader deal with the paperwork that comes back. Focus mode guards the calling block. A rep with 25 open deals, each with a dated next step, fits inside all of it with room to spare.

Pay the first week a free limit makes you delete a task to add a new one, or skip a reminder you needed. For most sellers that's TickTick or Todoist first, and the cheapest of the two is Todoist Pro at US$60 a year.

A follow-up app is only as good as the reminder that reaches you. Android makes a few choices of its own, and they decide whether the 4pm callback rings at 4pm.

• Check the battery setting of your task app first if reminders land late. Android's developer guide to Doze says a phone left unplugged and still for a while holds back standard alarms and syncs until a short maintenance window.
• Widgets go on the first home screen.
• Schedule Focus mode for the same hour as your calling block, and pick the best time to make sales calls before you set it.
• In Do Not Disturb, allow calls from your clients and switch on repeat callers, so a buyer who rings twice gets through while the group chats, the news alerts and the shopping apps wait until your calling block is over.
• Keep one app per job, because two task apps means two lists and the follow-up always ends up on the one you didn't open.

Give the calendar the same treatment. Never blocked out time for follow-ups? Read the guide to timeboxing first.

A task app holds the promise. It doesn't hold the conversation behind it: what the buyer said, which quote they have, and the chat where they asked about delivery. With a dozen clients, your memory fills the gap. Past a dozen, these start happening:

• Before each callback you scroll WhatsApp to remember what you said last time.
• A task says "call Marcus", and you can't remember which Marcus.
• Your manager asks where a deal stands, and you rebuild it from three apps.
• A client went quiet for a month, and nothing reminded you because the task was deleted.

If two of those are true, your follow-ups belong in a CRM, with each task on the client's record. Compare a few on the best CRM for small business list, and use the sales follow-up process to decide how often to chase and when to stop.
