A Forest app alternative that grows an aquarium instead of a tree

Forest is a focus app in which a virtual tree grows while you stay focused and is added to your forest when the session finishes. According to Forest's own website, the tree dies if you switch to other apps mid-session, a Deep Focus mode can block selected apps, Plant Together lets friends grow the same tree, and Forest works with Trees for the Future to plant real trees. It runs on iPhone, iPad, Android, Chrome and Firefox.

People usually go looking for a Forest alternative for one of three reasons: they want a different reward than trees, they find a withering tree more stressful than motivating, or they want more to collect and explore over months of use. None of those make Forest a bad app. They are differences in taste, and Pondoro is built around a different set of choices.

The table below compares the two apps feature by feature. Forest details come from Forest's website as of October 2026; check it for current plans and prices.

Pondoro rewards finishing without punishing leaving. The timer is anchored to the moment you pressed start, so locking your phone or switching apps does not pause it, and a Live Activity keeps the session on your Lock Screen. If you step away for more than 60 seconds, that counts as a disturbance: one disturbance leaves the water rippled, two or more make it murky. The session still counts, coins and XP still land when it ends, and the shy creatures simply wait for a calmer dive.

Every session is also a dive.Depth Dive turns how you focused into what you find. Session length picks the depth (Shallows under 20 minutes, Reef for 20 to 39, Twilight Zone for 40 and up), the hour you start picks the tide (dawn, day, dusk or night), and staying undisturbed keeps the water crystal clear. Each dive logs one sighting from 24 sea creatures, with 6 seasonal migrations that return each year and rare "while you were away" moments revealed in the recap.

Breaks and streaks are gentle on purpose. Breathing breaks end on time and are spent breathing slowly with your fish instead of scrolling. Miss a day and the streak rests rather than resetting to zero.

An honest comparison has to say this part out loud. Choose Forest if any of these matter most to you:

• You use Android or want a browser extension on your laptop. Pondoro is iPhone only.
• You want your focus time connected to real tree planting.
• You like the strict rule that leaving the app costs you the tree, and the pressure helps you.
• Your study group already uses Plant Together.

Choose Pondoro if you are on iPhone and want a calmer reward loop with more to discover: an aquarium to grow, fish to collect and breed, a Field Guide to fill, and no penalty that makes one bad session feel like a loss.

1. Install Pondoro and skip the account. Everything works as a guest on your device; sign in later only if you want sync.
2. Pick the session length you already use. Classic 25 is the default, and Custom covers 5 to 180 minutes in 5-minute steps.
3. Turn on Deep Focus and choose the same apps you blocked before.
4. Name your intent and start. Finish the block to collect coins and XP and see which creature you met.
5. Invite your focus friends to a Shared Pond if you used Plant Together.

Forest and Pondoro do not share data, so your forest stays in Forest. Pondoro starts fresh with a starter fish and an empty Field Guide.

Pondoro is free to start, and the free plan includes the focus timer, Deep Focus app blocking, the living reef, streaks, and fish to collect. Pondoro Plus is optional at $4.99 a month, $29.99 a year with a 3-day free trial, or $49.99 once for lifetime access. Plus doubles the coins you earn, unlocks every fish rarity, and adds timer layouts, themes and soundscapes. There are no ads and no paid coin packs. Forest describes a free tier and an optional Plus subscription whose price varies by region, so compare current prices in the App Store before you decide.

If what you liked about Forest was the game feel, the focus game guideexplains how Pondoro's rewards stay tied to real focus. If you used Plant Together with friends, read about the study with me timer and Shared Ponds. For the timer itself, start with the Pomodoro timer for iPhone or, for long sessions, the deep work timer guide. Everything else is on the Pondoro homepage and in the Pondoro focus guides.
